Many are made to our specifications by some of the world’s finest makers of loudspeaker components. Please note the Compatibility Group designations for each driver. They show which drivers sound best with which other drivers, although any combination will result in a good loudspeaker system.

KVG Laboratories 1TCD6 1-inch Ceralum Dome Supertweeter.

Stacks Image 1229
The 1TCD6 tweeter is a very compact dome tweeter designed for an airy, open sound and superlative spatial imaging. It has a smooth, extended high frequency spectrum with low 2nd and 3rd harmonic distortion. Its off-axis response is excellent. An aluminum dome is well-damped by applying a coating of a microscopic layer of bismuth ceramic, suspended by a highly compliant fabric surround to reduce edge resonance. The voice coil is treated with ferrofluid for improved cooling to reduce power compression. The neodymium magnetic assembly is shielded to reduce the effects of stray magnetic fields on other components. A hexagonal phase shield improves amplitude response and protects the fragile dome from errant fingers. The aerodynamically-shaped back chamber provides a low free air resonance of 700 Hz, easing integration with smaller woofers and all midranges.

KVG Laboratories 1TGD8 1-inch Gold Reference Dome Tweeter.

Stacks Image 1248
The 1TGD8 has a gold-plated titanium, cantenary-shaped dome that dramatically reduces distortion occurring at the apex of the dome. This shape prevents out-of-phase break-up modes. The result? Vivid spatial imagery, and a tweeter that is very revealing of subtle details of the music because of its smooth, clean and effortless sound. Ultra-linear amplitude response results from the tweeter’s vented magnet pole piece and its damped-and-tuned rear chamber. Build quality is evidenced by is CNC-made solid aluminum faceplate.

KVG Laboratories 1TSD8 1-inch Polymer-Coated Silk Dome Tweeter.

Stacks Image 1404
Fatigue-free, warm sound combined with excellent stereo imaging defines the 1TSD8 tweeter, used in our entry-level loudspeakers. The dome is hand-balanced for low distortion. It features a computer-optimized back air chamber for extended frequency response, and a tightly-focused magnetic field for fast transient response with low distortion. The tweeter is designed to be used with an unusually low crossover frequency of 1,700 Hz to allow the finished loudspeaker to behave as an acoustic point source, providing the listener with a 3D-like stereo image, reduced listener fatigue and a wide listening “sweet spot.” This is the tweeter used in our K-61NF, “The Biggest Sounding Little Speaker.”

KVG Laboratories XK010DT 1” Rubberized Silk Dome Tweeter.

Stacks Image 1396
Here’s a personal favorite of our designer, found in some of our specialty designs, along with the speakers he made for his previous company, Specialized Recording and Audio, during the 1970s and 1980s. plus, we love vintage sound! If you do too, we had you in mind with this crystal clear 1-inch tweeter. It’s a faithful reproduction of the classic Peerless dome tweeter used in many 1970s-era studio monitors, as well as highly-regarded home loudspeakers made by ADS, Cizek, IMF, Infinity, Jennings Research, Miller & Kreisel, Paradigm, Polk Audio, DLK, Domus, and many more. Try if you want, but you can’t make this tweeter sound bad! We did substitute a polymer faceplate for the milled aluminum one used in the original, but this actually improves the high-frequency response by reducing parasitic capacitance.

Compatibility Group: B

KVG Laboratories 1TTD8 1.3” Coated Textile Dome Reference Tweeter.

Stacks Image 1388
Featuring the smoothness and warmth of soft dome tweeters with the clarity and detail of metal tweeters, the 1TTD8 is an ideal choice for a good all-around high-end two-way or multi-way loudspeaker. Equally suited for use in the studio or at home, its high power handling and high sensitivity provides wide dynamic range without harshness or power compression. Its low resonance frequency, 800 Hz, eases integration with the loudspeaker’s other drivers and allows for a point-source design. Its off-axis response mirrors its on-axis response, creating a deep, very-detailed and accurate spatial image with a wide sweet spot.

Compatibility Group: B

KVG Laboratories 1TDO-8 Orthodynamic Supertweeter.

Stacks Image 1380
Orthodynamic supertweeters differ from other designs by winding the voice coil in a flat spiral that is then bonded onto the diaphragm. This causes the diaphragm to be driven evenly over its entire surface, greatly reducing distortion, increasing clarity and virtually eliminating colorations. The orthodynamic method of construction greatly reduces the diaphragm’s mass, allowing improved transient response and reproduction of high frequencies out to 40,000 Hz. Our supertweeter has an ultralight polyimide diaphragm with an ultrasound-bonded aluminum voice coil. It’s a great choice for high-end studio and home loudspeakers.

Compatibility Groups: A, C

KVG Laboratories 1THO-8 Horn-Assisted Orthodynamic Supertweeter.

Stacks Image 1372
Adding a short horn to an orthodynamic tweeter creates a supertweeter with unrivaled dynamic range and extremely low distortion, very accurate precisely-focused spatial imaging, and a level of clarity you have to experience to believe. This supertweeter reveals every nuance of music, every subtlety, the smallest delicate detail. The horn lacks the honk and nasality of most horns. Instead, it serves to reduce distortion while focusing the treble away from the side walls and ceiling - removing the adverse effects of your room’s acoustics on the clarity of the treble. Orthodynamic tweeters differ from other designs by winding the voice coil in a flat spiral, in this case a rectangular spiral, that is then bonded onto the diaphragm. This causes the diaphragm to be driven evenly over its entire surface, greatly reducing distortion, increasing clarity and virtually eliminating colorations. The orthodynamic method of construction greatly reduces the diaphragm’s mass, allowing improved transient response and reproduction of high frequencies out to 40,000 Hz. Our supertweeter has an ultralight polyimide diaphragm with an ultrasound-bonded aluminum voice coil. It’s a great choice for high-end studio and home loudspeakers.

KVG Laboratories XC137PR-8 and XC137PR-4 2” Phenolic Ring Tweeters.

Stacks Image 1364
Here’s a personal favorite of our designer, found in some of our specialty designs, along with the speakers he made for his previous company, Specialized Recording and Audio, during the 1970s and 1980s. We use them for innovative new designs (not just restoration work), especially for acoustic instrument amplifiers, unique PA and disco speakers, playback of streaming audio, MP3s, 78-rpm analog discs, and both satellite and terrestrial radio. This tweeter has a smooth, natural sound, with the uncanny ability to hide flaws in a recording’s treble — making the recording sound better — without sounding dull, harsh or muffled. Don’t let the fact it’s a cone scare you. It sounds great! This isn’t one of those awful-sounding cheap cone tweeters you’ve heard in the worst-sounding stereos. If fact, it’s one of the most-natural-sounding tweeter you’ll ever hear. Instantly recognizable by the orange ring, made from phenolic, that is the origin of its name, the Phenolic Ring Tweeter is the very essence of “vintage sound.” Originally made by CTS and by Pioneer, the Phenolic Ring Tweeter is easy to use, never sounds bad, and is a perfect match for the dispersion patterns, tone and transient response of traditional paper cone woofers. The secret is that ugly Phenolic Ring: it allows the paper cone to vibrate freely while reducing harsh-sounding edge resonances. Phenolic Ring Tweeters are found in many classic speakers, including Acoustic Research, DLK, Marantz, Altec, AVID, BIC Venturi, Fisher, Martin, Pioneer and many others.

KVG Laboratories XLE254 1.4” Cone/Dome Acoustic Suspension Tweeter.

Stacks Image 1356
Here’s a personal favorite of our designer, found in some of our specialty designs, along with the speakers he made for his previous company, Specialized Recording and Audio, during the 1970s and 1980s. If you’re a music lover who just wants to kick back and enjoy your music, this is an ideal choice. You won’t find a tweeter that makes listening to music more fun! Based on the classic JBL LE25-4 tweeter, our version has been made to recreate the best aspects of the original while reducing the few limitations of the original. It has a very warm, pleasant natural sound and is smoother the original; distortion is lower than the original as well. The original JBL LE25 tweeter was found in both studio monitors and home loudspeakers, especially the JBL 4311 studio monitor that was ubiquitous in studios and radio stations throughout the USA during the 1970s, along with the L100 Century - the home version of this classic studio monitor. Its foam suspension ring provides incredible transient response, despite the weight of the cone. The tweeter’s acoustic suspension design allows very low crossover points and its long voice coil provides wide dynamic range. Other classic JBL models with the original LE25 series tweeter include the L25, L45A, L45B, L71, L88A, L88P, 4311B, 4312, L16, L26 Decade, L36, R82, R103, R123, R133, and L120 series. Almost no other tweeter defines the sound of the ‘70s like the LE25.

KVG Laboratories XHCD35-8 Constant Directivity Supertweeter

Stacks Image 1742
Able to leap tall transients in a single bound. Faster than a cymbal hit. More powerful than a dome tweeter. It's Supertweeter! Smooth sound from its phenolic matrix diaphragm, incredible dynamic range with low distortion from its constant directivity horn - which needs far less eq than most "CD" horns, only 6 to 10 dB, not the 15 to 20 dB most horns need. Horn tweeters are common in many highly regarded vintage loudspeakers, such as those from Cerwin-Vega, Klipsch, Altec, JBL, KLH and many others. Why horns? Aren’t horns just for PA systems? Well, no. The efficiency of a horn supertweeter provides designers a cost-effective way to reproduce treble with low distortion, excellent clarity and superlative transient response. You’ll hear the subtle “tick” of a drumstick on cymbals in a way no other type of tweeter can reveal such a fine music detail. We chose a design that captures the spirit of vintage loudspeakers for those who love that sound, yet is still capable of the high level of detail, pace and timing demanded by today’s home theater setups and dedicated audiophiles. And yes, it can work perfectly with the highest-quality PA systems too.

Compatibility Groups: A, B, C and D.

KVG Laboratories M5C-8 Cone Midrange

Stacks Image 1348
The M5C-8 cone midrange has an extremely flat frequency response from 70 Hz to 6000 Hz, making it ideal where high fidelity is required, such as studio monitors and reference speakers. Its excellent off-axis frequency response up to 4000 Hz allows it to seamlessly blend with many tweeters for a great sounding loudspeaker. It has a specially treated paper cone with a half-roll nitrile-butadiene synthetic rubber surround for outstanding durability. An aluminum alloy demodulation ring is installed above the magnetic pole piece to reduce stored energy and inductance. This dramatically reduces distortion, especially in the critical vocal range. If your vocals don’t sound good, then nothing else matters.

Compatibility Group: B

KVG Laboratories DAART-2 Dynamic Aluminum Alloy Reference Transducer 2” Dome Midrange

Stacks Image 1340
The DAART-2 dome midrange creates superlative spatial imaging because of its excellent off-axis frequency response. A black anodized 2" diaphragm has extremely linear frequency response both on-axis and off-axis throughout the midrange and lower treble, allowing a seamless transition to the loudspeaker’s tweeter. Superior dispersion characteristics eliminate notches in its frequency response. High quality construction is evidenced by its cast-aluminum faceplate and rugged protective metal grill. Its clarity results from its resonance-reducing vented voice coil former, and the copper shorting ring installed on its magnet pole piece to reduce distortion caused by magnetic effects.

Compatibility Group: A

KVG Laboratories 6WPLP-8 6” PLP Cone Woofer

Stacks Image 1324
The 6WPLP-8 was developed to give you “the best bang-for-the-buck” sound, especially in compact loudspeakers. Its bass output will surprise you, which is why it was chosen for our K-61NF “The Biggest Sounding Little Speaker.” The PLP cone provides a wide range of piston-mode behavior while effectively damping the resonances that cause nasty-sounding break-up modes (untamed resonance peaks that give a woofer a harsh-sounding midrange sound). Also, the PLP cone achieves smooth frequency response. The woofer’s high-temperature aluminum voice coil and vented pole piece increase power handling without power compression effects. Long service life is assured by the use of a Santoprene surround, anti-hygroscopically-treated cloth dust cap, and an extended bump plate to reduce the incidence of mechanical damage when the woofer is played loudly.

KVG Laboratories 6WKM-8 6” Kevlar/Aramid Fiber Matrix Woofer.

Stacks Image 1316
A compact exotic woofer optimized for lively, dynamic bass reproduction in small or medium vented systems. Its critical midrange clarity and tonal balance is exceptional. As we keep saying, if the midrange isn’t good, then nothing else matters. Pace, timing and microdynamics are excellent. This woofer’s cone is made from a new Kevlar/aramid fiber matrix, so the cone weighs less than other cones of similar size, is more rigid than other cones, without severe break-up modes (untamed resonance peaks that give a woofer a harsh-sounding midrange sound). The cone is hand-coated with a special damping compound to further reduce break-up modes and damp structural resonances. The woofer features a central phase plug to eliminate air compression and internal air volume resonance, while improving frequency response and lateral dispersion. Its aluminum-former voice coil and composite rear-suspension “spider” contribute to its linear operation at high power levels. Build quality is excellent, as seen by its massive aluminum die-cast basket carefully engineered to minimize structural resonances. Finally, it has a shielded magnet structure so it can provide outstanding sound in audio/video applications.

KVG Laboratories 5GFM8 5-1/4” Woofer.

Stacks Image 1692
Designed to provide powerful, crystal-clear bass, vivid stereo imaging, excellent pace and timing, and the ability to reveal the most minute micro-dynamics of any format of recorded music — and it achieves it in a small cabinet. This 5-1/4” midbass delivers an amazing 102 dB at 53 Hz in a cabinet smaller than 1/2-cubic foot. That’s really loud, especially when you have a stereo pair playing. It maintains a tight tolerance of +/- 2 dB from 55 Hz to 5000 Hz, and +/- 1dB from 55 Hz to 2000 Hz, ensuring accuracy. Even 45-degrees off-axis its frequency response stays within 2 dB of the on-axis response up to 2000 Hz, making this an ideal point-source design. Clear, authoritative bass is provided by its powerful ferrite magnet system that is coupled to a precision suspension system, containing both a linear spider design and a rubber surround. The motor has an aluminum magnet shorting ring to reduces voice coil inductance, resulting in both extended frequency response performance and reduced distortion. The long-throw voice coil creates high excursion limits, allowing the low distortion and linear motion needed for signal clarity. The Glass Fiber Matrix Composite Cone provides an ideal balance of rigidity and self-suppression of undesired resonances, along with an absence of break-up modes. The cone’s neck is vented to reduce distortion caused by air compression during high-excursion conditions. The truncated cast aluminum basket provides structural rigidity, heat sinking capacity for the motor, and additional air venting under the spider to further reduce air-compression-caused distortion.

The DAART-7 has only one goal— extremely low distortion. It was carefully designed and computer-optimized for the highest audio performance with the lowest distortion levels. Exceptional clarity, uncompromisingly-revealing detail, and lively, well-controlled dynamics, with incredibly low distortion define this woofer. Pace, timing and microdynamics are excellent. Fanatic attention to detail is its secret: a central phase plug to eliminate air compression and internal air volume resonance, while improving frequency response and lateral dispersion, dual magnetic circuit shorting rings for lower distortion, highly compliant suspension with low-loss rubber surround for deep bass output, anodized carefully-shaped anodized aluminum cone for flat frequency response and freedom from harshness.

KVG Laboratories 10KA26 10” Acoustic Suspension Woofer.

Stacks Image 1284
Here’s a personal favorite of our designer, found in some of our specialty designs, along with the speakers he made for his previous company, Specialized Recording and Audio, during the 1970s and 1980s. Made for us by a renowned manufacturer, this is an improved and modernized version of the woofer used in the famous vintage Dynaco A25 loudspeaker system. It has a wonderfully-smooth and well-controlled roll off at 2000 Hz. This means this woofer is unique: it can be used in a 2-way design by letting the woofer run full range without a crossover’s low-pass filter. It has a magical retro sound to it. A classic vintage press-molded paper cone with matching natural rubber surround produces its smooth response and greatly reduces potential resonance problems. The woofer’s four-layer voice coil creates the large inductance and powerful driving force required to create its well-behaved roll off characteristic. The magnet system’s pole piece is a tee-shaped for low modulation distortion. An extremely stiff, dimensionally-stable injection molded metal basket keeps all critical components in perfect alignment. Large windows in the basket — both above and below the spider — reduce sound reflection, air flow noise and cavity resonance to a minimum. This is as close to a fool-proof woofer as technology allows.

KVG Laboratories 8CMT-8 High Output Coincident Midrange/Tweeter

Stacks Image 1683
Dynamic, articulate, smooth and tightly-focused midrange and treble characterize this point-source design. It mounts our HT1000P tweeter driver in the center of a high-sensitivity large-format cone midrange. Don’t let the size worry you, its off-axis is smooth and wide. Spatial imaging is accurate and deep. Vocal reproduction is outstanding - remember, if your vocals don’t sound good then nothing else matters. A treated cloth cone edge suspension effectively damps cone edge resonances and our hand-applied coating eliminates “cone cry” when the driver is played loudly, stiffening the cone to improve subtle details at the same time. The built-in exponential horn mounted in the center of the cone (behind the acoustically-transparent dust cap) radiates sound from the tweeter driver with no distortion, and no “honking”. The tweeter horn’s 60-degree coverage pattern directs sound away from the cone, reducing the frequency modulation effects that are a common problem with the increased distortion and treble harshness of most coincident and coaxial loudspeaker systems. It also minimizes adverse interaction between your room’s acoustics and the loudspeaker, and is one reason this unit has such outstanding spatial imaging. Designed for studio monitors, home theater systems, audiophile systems and even compact PA systems and acoustic instrument amplifiers.

KVG Laboratories 6XR/WC-8 Wood Cone Point Source Fullrange

Stacks Image 1276

Compatibility Group: None, this driver is unique to its application.

For Hi Fi enthusiasts who prefer loudspeakers lacking a crossover network, this fullrange has an amazingly warm, very detailed sound. The thin Sapeli cone is lightweight like a carbon fiber cone, with a warm, clear sound that outperforms a paper cone. It’s been carefully crafted to avoid the problems caused by the directionality of the wood grain. It’s equally as rigid in all directions, not just across the grain. It will bring out tones and sounds that other cones simply cannot reproduce. Combined with the vivid spatial imaging created by its point-source design, it’s a wonderful listening experience for all types of music, especially classical, jazz, orchestra and every genre of music which emphasizes woodwinds, strings and brass. Vocals have a depth and naturalness that is breathtaking. Requires our DSP Spectral Assist System (DSP/SAS) and recommended cabinet designs for proper operation.

These drivers are sold in matched pairs with one of two dedicated DSP Spectral Assist Systems (fancy name for a fancy equalizer). The cabinet is critical, and you need a battery of test gear to adjust everything, so we’re selling them only in finished speaker systems. Each driver has its own DSP/SAS channel matched to it, a task not for the DIYer. The box is only about 9.5 liters, so these aren't huge speakers - yet they produce 106 dB SPL (1 meter) from 45 Hz to 20,000 Hz. Not bad for a 6-inch fullrange!

Base price, per matched pair, is $1,600.00 USD - which includes cabinets made from 1.9 cm plywood, nicely stained and finished; with the entry level DSP/SAS system and our house brand of cable and connectors. The higher-end DSP/SAS adds $200.00 to the per-pair price. Other materials and finishes would be extra, and we’re happy to use any brand of wiring to match the internal wiring to cables connecting to the amplifier -- if that's an issue (adds a slight up-charge for the exact difference in cable costs).

The basic DSP-SAS is analog-only input and output, 28/56-bit internal processor, 98 dB dynamic range, 0.05% THD; the upgraded DSP-SAS add TOSLINK I/O up to 192 kHz/24-bit, 0.003% THD and 103 dB dynamic range.
