Speaker Drivers Tweeters
Speaker drivers are the individual electro-acoustic transducers that function as the core components of any loudspeaker system. This category covers the different types and their roles: woofers for reproducing low frequencies, mid-range drivers for vocals and instruments, and tweeters for high-frequency detail. This page is a directory of brands that manufacture these fundamental building blocks of sound for both commercial speaker builders and DIY enthusiasts.

Aeron
AERONS supplies professional sound equipment for live events, public-address systems and permanent installations in India. Its catalogue covers line arrays, power amplifiers, mixers, microphones, signal processing and installation speakers, alongside equipment from international brands it distributes. The business traces its roots to radio and loudspeaker work in 1962; its own history identifies 2000 as an export-business milestone, not its founding year. Its work spans the equipment needs of venues, installers and sound-reinforcement operators, from microphones and mixing to amplification and loudspeaker coverage.
Atohm
Atohm develops the drive units as well as the finished loudspeaker, and also supplies drivers and kits to people building their own systems. Thierry Comte established the French business behind the brand, Welcohm Technology, in 2000. Its catalogue connects GT and Sirocco loudspeakers with Rafale subwoofers, amplification and ZEF cables. The GT technical platform illustrates the detail of its driver engineering: the Absolute Series tweeter combines a treated silk dome, a neodymium motor and a copper ring intended to reduce and linearise inductance. Motor geometry and dispersion are developed together with the diaphragm and suspension. The same engineering interests extend into its component and DIY offerings.
BC Speakers
B&C Speakers is an Italian specialist in professional loudspeaker transducers, supplying both its own catalogue and OEM designs to manufacturers worldwide. Its roots reach back to Roberto Coppini and Fernando Borrani’s post-war work in Florence; the company identifies 1946 as the start of continuous production. From its facility in Bagno a Ripoli, B&C develops and manufactures low-frequency cone drivers, compression drivers, coaxial units, horns and line-array components for touring systems, installed sound, cinemas and high-output monitors. Engineering combines finite-element modelling, material development, precision machining and rigorous power and reliability testing. The wider group also includes Eighteen Sound, Ciare and Eminence, but B&C retains its own product programme and Italian manufacturing identity. The entry title remains unchanged for import matching, while the description uses the manufacturer’s correct B&C styling.
Camerton
Camerton Audio develops its own flat-diaphragm wideband and isodynamic drivers for loudspeakers and headphones. Oleh Lizohub founded the company in Ukraine in 1999, moved to Germany in 2011 and relaunched Camerton in Berlin in 2019 after working as a senior engineer at Voxativ. The Binom-1 loudspeaker uses a single proprietary wideband driver to cover most of the audible range without a conventional multi-way crossover. Binom-A makes the underlying driver available as a separate component, while the open-back Binom-ER headphone uses Camerton’s large dual-sided isodynamic transducer. These products are designed and handmade on a very small scale by Lizohub. The old description incorrectly presented single-ended-triode amplifiers as part of Camerton’s speciality. The brand’s own work is transducer engineering, with efficient loudspeakers that can partner low-powered amplifiers but no current amplifier line of its own.
Celestion
Celestion has shaped both electric-guitar tone and professional loudspeaker engineering from the level of the drive unit itself. The story began in 1924, when Cyril French worked with Eric Mackintosh to develop one of the earliest practical cone loudspeakers; Celestion was initially the product name before becoming the company identity. The British manufacturer is now best known for guitar speakers such as the Blue, G12M Greenback, G12H, Creamback and Vintage 30, whose controlled cone breakup is treated as part of an instrument amplifier’s sound rather than unwanted distortion. Its professional range includes ferrite and neodymium low-frequency drivers, compression drivers and coaxial units for sound reinforcement. The AxiPeriodic Axi2050 is a notable modern development, covering roughly 300 Hz to 20 kHz with one annular diaphragm and avoiding a midband crossover. Celestion also supplies impulse responses and Dynamic Speaker Responses, translating its physical driver catalogue into tools for digital cabinet simulation.
Cube
Cube Audio is a Polish loudspeaker and driver manufacturer founded by physicist Grzegorz Rulka and loudspeaker designer Marek Kostrzyński. The company’s central project is the high-performance full-range driver: a transducer expected to reproduce most or all of the audible spectrum without a crossover dividing the critical midband. Cube develops and builds its own large paper-cone drivers, magnet systems, suspensions and field-replaceable elements, then matches them to carefully tuned cabinets. The Nenuphar family demonstrates the purest version of the idea, using a single wideband unit per channel and a cabinet loading system engineered to extend bass without sacrificing immediacy. Other models adapt the same driver knowledge to different room sizes and bandwidth requirements. Removing the crossover can improve phase continuity and point-source imaging, but it places unusually high demands on cone profile, moving mass and motor linearity; those are the areas where Cube’s know-how resides. The brand is therefore more than a boutique cabinet maker: it controls the transducer technology that gives its loudspeakers their distinctive coherence and directness.
David Laboga
David Laboga Custom Audio is a Polish cable manufacturer whose credibility was built first with working musicians and studios, then extended into high-end home audio. David Laboga founded the company around instrument, microphone and loudspeaker-cabinet cables; the original Perfection Gold series was developed for professional performers and became associated with artists including Al Di Meola, Steve Lukather, Tommy Emmanuel and Steve Stevens. The domestic-audio range now covers analogue interconnects, loudspeaker and power cables, USB and Ethernet connections, with Emerald, Expression Ruby and newer Akoya Reference products marking different technical levels. Rather than rely on one conductor recipe across every interface, the company hand-braids copper conductors of selected purities and gauges, develops connector bodies and termination methods for each application, and sometimes offers digital cables with or without the 5-volt supply path. Leather sleeves, custom copper plugs and gemstone details give flagship models a distinctive finish, but the useful story is continuity between stage durability and listening-room refinement: these cables come from a maker experienced with both professional signal chains and audiophile systems.
Davis Acoustics
Davis Acoustics is a French loudspeaker company founded in 1986 by electroacoustic engineer Michel Visan after his work at Audax and as technical director of Siare. It began as a driver manufacturer, and its first product, the 13KVL5A mid-bass unit, already used a braided Kevlar cone. Davis then expanded into DIY kits in 1988 and complete loudspeakers with the DK200 in 1993, while continuing to design transducers for its own systems and OEM customers. That vertical expertise remains the brand’s strongest differentiator: Kevlar, carbon fibre, fibreglass, paper and wideband membranes are selected and formed according to the required mass, stiffness and damping rather than used as decorative claims. Finished ranges such as Ariane and Courbet cover conventional stereo and home cinema, while specialist drivers and kits preserve the company’s close relationship with builders. The last wideband project led by Michel Visan, the 20DE8, also became the basis of the single-driver MV One. Davis Acoustics therefore connects French driver engineering, accessible kit culture and complete loudspeakers within one unusually continuous manufacturing history.
Dayton Audio
Dayton Audio is the house audio brand associated with Ohio-based Parts Express, serving builders, installers and value-conscious listeners with components that are normally sourced from many separate suppliers. Its catalogue spans individual tweeters, midrange and woofer drivers, passive radiators, subwoofer plate amplifiers, class-D amplifier boards, DSP modules, finished subwoofers, compact speakers and complete kits. Reference and Signature drivers provide measured parameters for original loudspeaker designs, while Ultimax subwoofers prioritise long excursion and power handling. Just as important is the supporting tool chain: the DATS measurement system helps builders determine driver impedance and Thiele-Small parameters, and project documentation makes the parts usable rather than merely inexpensive. Dayton also collaborates with independent designers on kits and supplies OEM or custom-installation solutions through Parts Express. Its distinctive strength is breadth with technical accessibility — drivers, electronics, measurement and practical documentation within one ecosystem — making it especially useful to DIY loudspeaker builders who want compatible parts and test tools from one source.
DD Audio
DD Audio, originally Digital Designs, is an American mobile-audio manufacturer founded by Jassa and Vicki Langford in Southern California in 1986 and based in Oklahoma City since 1991. The company is best known for high-output subwoofers that are engineered and hand-built in the United States, including reconeable competition-oriented models rather than sealed imported assemblies. DD develops motor structures, voice coils, suspensions and cone systems around defined power and excursion requirements; its Z-series neodymium architecture represents the extreme sound-pressure end of that work, while 2500, 3500 and 9500 families serve progressively more demanding daily and competition systems. Amplifiers, component speakers, pro-audio-style Voice Optimized drivers and vehicle-specific or universal enclosures complete the signal chain. The catalogue also extends to marine products, but car audio remains the centre of gravity. DD Audio’s individuality lies in retaining domestic subwoofer engineering, assembly and service capability while spanning both sound-quality installations and very-high-SPL competition — two uses that demand different alignments, cooling and mechanical durability.
Fostex
Fostex connects Japanese transducer manufacturing with tools used by recording engineers, musicians and hands-on loudspeaker builders. The company was created in 1973 as an independently managed subsidiary of Foster Electric, whose OEM loudspeaker experience gave the new brand an unusually deep production base. In 1974 it introduced RP, or Regular Phase, technology: a planar diaphragm carrying a printed conductor and driven across its surface in phase. Successive RP generations power the long-running T50RP family and newer premium planar-magnetic headphones, while the TH series explores dynamic drivers and crafted wooden housings. Fostex also makes active studio monitors, field and multitrack recorders, headphone amplifiers, microphones and professional accessories. A second, equally distinctive part of the catalogue is its raw loudspeaker components, including full-range drivers, compression tweeters and enclosure kits used in commercial and DIY designs. That breadth explains why the name appears both in studios and in enthusiast-built speaker systems.
Line Magnetic Audio
Line Magnetic Audio is a Chinese high-end manufacturer whose work connects present-day valve electronics with the engineering of Western Electric, Altec and Jensen cinema systems. Brothers Zheng Cai and Zheng Xi founded the company in Zhuhai in 2005 after years spent repairing, collecting and studying historic amplifiers, field-coil drivers and horns. The company first became known for painstaking replicas of classic loudspeaker drivers and theatre electronics, then developed an extensive range of original integrated amplifiers, preamplifiers, power amplifiers, digital sources and loudspeakers. Single-ended Class A models built around 845, 805, 211 or 300B output valves are central to the catalogue, while push-pull designs offer greater power for less sensitive speakers. Products such as the LM-845IA, LM-805IA and LM-88IA show that Line Magnetic does not rely on a single tube topology. Large output transformers, point-to-point wiring in many valve models and user-accessible bias adjustment reflect practical manufacturing know-how. Its horn systems and replica drivers preserve a separate, historically informed side of the business. Line Magnetic’s individuality lies in learning directly from early cinema audio while producing usable contemporary components rather than decorative copies.
Linkwitz
Linkwitz is the commercial continuation of loudspeaker research by Siegfried Linkwitz, the German-born engineer whose name is also attached to the Linkwitz–Riley crossover. During his career at Hewlett-Packard and in decades of independent work, Linkwitz examined how loudspeaker directivity, room reflections and human hearing combine to create a believable stereo image. His later systems reject the conventional box: the Orion, LXmini and flagship LX521 use dipole or carefully controlled radiation, active line-level crossovers and dedicated amplification for each frequency band. The four-way LX521 separates its open-baffle midrange and treble structure from opposed woofer frames, controlling both stored cabinet energy and the pattern of sound launched into the room. It can be implemented with a precision analogue signal processor or supported DSP configuration rather than a passive crossover. The compact LXmini uses an omnidirectional/dipole concept built around simple tubular structures, while LXstudio adds dedicated dipole bass. After Linkwitz’s death in 2018, authorised plans, component sets and completed systems continued through LINKWITZ.store. The brand’s value is unusually transparent engineering: design theory, measurements, placement requirements and construction routes are documented for both owners and DIY builders.
Morel
Morel is an Israeli loudspeaker and drive-unit specialist whose complete home and car systems are grounded in nearly five decades of transducer manufacturing. Meir Mordechai founded the company in 1975; the name derives from Mordechai Electro-acoustics. Morel remains family owned and develops raw drivers as well as finished products, giving it control over the motor, suspension, diaphragm and enclosure rather than forcing a speaker design around catalogue parts. The brand’s signature technologies include large External Voice Coils, which place the magnetic motor inside the coil for efficient use of magnetic energy, and Hexatech aluminium wire shaped to pack the winding with minimal air gaps. Hybrid neodymium/ferrite magnet systems, damped polymer composite cones and soft-dome midrange units appear across different applications. Home-audio lines such as Sopran, Avyra and Högtalare sit alongside architectural models, car-audio components and OEM drivers supplied to other makers. Morel’s distinction is therefore broader than a particular “sound”: it is the unusual overlap of specialist driver engineering, hand assembly and the ability to carry the same motor and diaphragm know-how from a raw transducer to a complete loudspeaker.
Mundorf
Mundorf is the German component specialist whose capacitors, coils, resistors and tweeters sit inside many loudspeakers and amplifiers sold under other names. Raimund Mundorf began offering high-quality crossover parts to hi-fi enthusiasts in 1985, turning a personal interest in improving loudspeakers into an engineering and manufacturing business in Cologne. The company remains closely identified with the MCap family of film capacitors and with custom crossover production. Its catalogue includes polypropylene and foil capacitors, air-core and ferrite-core inductors, metal-oxide resistors, terminals, internal wiring, solder, power-supply capacitors and Air Motion Transformer tweeters. Foil-coil geometries, carefully controlled winding, impregnation and contact methods are used to reduce unwanted series resistance, inductance and mechanical effects; materials and construction vary clearly across the EVO, Supreme and other lines. Mundorf also develops complete crossovers and hand-built assemblies for manufacturers. The brand’s value is unusually concrete: it supplies the passive parts that determine filter accuracy, power handling and long-term reliability, while offering designers a wide ladder of dimensions and electrical characteristics rather than one universal “audiophile” recipe.
RFC
RCF is an Italian professional-audio manufacturer founded in Reggio Emilia in 1949, originally producing loudspeakers and microphones for other companies. The title “RFC” in this database is a transposition; the brand connected to the supplied rcf.it address is RCF. Decades of designing and manufacturing its own transducers remain central to the company: compression drivers, woofers, horns, enclosures, amplification and DSP are developed as parts of one system rather than assembled from unrelated modules. RCF was an early force in self-powered professional loudspeakers, and the ART series, introduced in the 1990s, became one of its most recognisable product families for portable PA, musicians and events. The current catalogue stretches from ART, NX and compact installation speakers to HDL line arrays and the high-output TT+ Audio range for touring, theatres and stadium-scale systems. SUB models, stage monitors and digital mixers complete the live-sound side, while D-Line and architectural products address fixed installations. RDNet provides networked control and monitoring of large systems; FiRPHASE processing is used to align phase response through the crossover region, and Bass Motion Control extends useful low-frequency behaviour while protecting the transducer. RCF’s value is the depth of that vertical integration. It can apply the same driver knowledge to a compact active cabinet and to a flown line-array module, then supply the electronics and software needed to deploy both predictably. The company is not a domestic hi-fi brand despite the similarity of some terminology: its reputation was built on reliable, intelligible and scalable sound for professionals.
SB Acoustics
SB Acoustics is an Indonesian loudspeaker-driver brand conceived in 2008 by Sinar Baja Electric together with the Danish engineering consultancy Danesian Audio. The previous 1981 date belongs to the older history of Sinar Baja Electric, not to SB Acoustics itself. This collaboration explains the brand’s unusual structure: transducers are developed in Denmark and manufactured in Indonesia in facilities with deep experience in cones, voice coils, motors and complete loudspeaker production. The standard SB range made carefully engineered tweeters, midranges, woofers and passive radiators accessible to both commercial manufacturers and DIY designers. Satori moves higher with refined motor systems, low-loss suspensions and diaphragms such as Egyptian papyrus, Textreme carbon fibre and proprietary composite constructions. Beryllium domes, ring-radiator tweeters and shallow-profile drivers extend the options for demanding two-channel, home-cinema and automotive designs. The company publishes detailed response, distortion and impedance data and supports complete kits, allowing a designer to work from measured behaviour rather than brand mythology. SB Audience, launched separately in 2020, applies the parent company’s manufacturing knowledge to professional sound-reinforcement drivers; it should not be confused with the core SB Acoustics hi-fi lines. Nor is the company simply an importer attaching a European name to generic units: the Danish-Indonesian partnership is the product strategy, combining specialised development with vertically integrated, repeatable production. SB Acoustics became influential because it offers serious transducer technology across price levels, from practical OEM and DIY drivers to ambitious Satori units that can anchor genuinely high-end loudspeakers.
Scan-Speak
Scan-Speak is a Danish manufacturer of premium loudspeaker transducers founded on 1 February 1970 by engineer Ejvind Skaaning. Based in Videbæk, it has spent more than half a century developing drivers for high-end loudspeaker companies and for advanced independent builders. The Classic range preserves proven constructions, Discovery broadens access to the company’s engineering, and Revelator and Illuminator introduced many of the technologies most closely associated with the name. Sliced-paper cones use radial cuts and damping adhesive to suppress breakup without sacrificing the natural behaviour of paper; Symmetric Drive motor systems reduce inductance variation and distortion as the voice coil moves. AirCirc magnet structures improve airflow behind tweeter domes, while beryllium, textile and ring-radiator high-frequency units provide different solutions rather than a single house material. The flagship Ellipticor family departs from circular geometry with elliptical voice coils and magnet gaps, distributing resonances and giving the designer control over dispersion and diaphragm behaviour. Scan-Speak also produces Automotive and Revelator Silver lines, subwoofer drivers and products tailored for OEM programmes. Development, precision assembly and extensive measurement remain centred in Denmark. The company is now part of the Eastech Group, but operates as an independently managed Danish business and retains its own engineering identity. Scan-Speak’s importance lies not in one famous cone or tweeter: it repeatedly turns research in motor linearity, moving mass, airflow and resonance control into durable driver families that other loudspeaker designers can use as the acoustic foundation of their own products.
TAD
TAD (Technical Audio Devices Laboratories, Inc.), a high-end audio brand and division of Pioneer, was initially focused on professional studio monitors. Founded by Bart Locanthi. Their entry into the consumer market began in 2002 with the TAD-M1 speaker system, unveiled at the Consumer Electronics Show (CES). The TAD-M1, and subsequent TAD speakers, are built around their proprietary CST (Coherent Source Transducer) Driver. This coaxial driver combines a beryllium tweeter dome and a beryllium midrange cone, achieving ultra-wide-range reproduction from 250 Hz to 100 kHz. The CST driver acts as a point source, providing uniform directional characteristics both horizontally and vertically, for natural sound dispersion. The use of beryllium is key: it’s the lightest and most rigid metal with high internal loss, ideal for reproducing ultra-high frequencies (including harmonic overtones that enhance the audible band). The shallow, large-diameter beryllium midrange also contributes to lower bass response. The CST Driver, incorporating high-precision processing and a proprietary vapor deposition technique for the beryllium diaphragm, represents the culmination of years of TAD’s technical expertise. The technology is found in models like the TAD Reference One (released 2007) and other speakers.
Voxativ
Voxativ is the Berlin loudspeaker company founded by engineer Inès Adler to pursue full-range reproduction without a conventional crossover. Its loudspeakers ask one highly specialised driver to cover most or all of the audible spectrum, avoiding the phase and integration problems created where separate bass, midrange and treble units hand the signal to one another. Making that principle work requires exceptionally light paper cones, carefully controlled suspensions and powerful magnetic motors. Voxativ designs and manufactures its own drivers in Germany, offering both permanent-magnet versions and field-coil models whose magnetic field is supplied electrically. The drivers are sold separately for specialist projects, but their natural context is the company’s complete loudspeakers. Ampeggio established the brand internationally with a rear-loaded horn folded inside a tall cabinet; the compact Hagen and Pi designs adapt the same single-driver logic to smaller rooms, while the modular 9.87 and 9.88 systems add dedicated bass sections when greater scale is required. Field-coil power supplies and low-powered amplification complete the ecosystem. Voxativ does not pretend that a crossoverless speaker is the universal answer: efficiency, cabinet loading and room placement are integral to the result. Its achievement is the depth with which one concept has been developed—from cone formulation and motor construction to horn geometry and complete systems—giving the brand a recognisable technical and musical character rather than merely another variation on a multiway box.
