The VR.thirty is the latest addition to the VR series of full-range loudspeakers and is the fullest expression of our price-to-performance paradigm. Affectionately referred to as the “Mini Seven,” after our ULTRA.seven model it resembles, the VR.thirty is our second design utilizing three ultra-fast ceramic honeycomb woofers; it also features a low-mass, high-definition ceramic midrange driver, our signature beryllium dome tweeter, and a rear-mounted ambient retrieval ribbon driver. Hand-built point-to-point crossovers wired throughout with MasterBuilt Reference cabling, the VR.thirty is available in either a passive or Foundation Hybrid Bass Management System. Powerful, deep, and nuanced bass, see through to the midrange, and detailed, extended high-frequency response are the VR.thirty’s hallmarks that every discerning music lover will find compelling. Like all VSA loudspeakers, the VR.thirty has no discernible sweet spot and can be enjoyed anywhere in the room.

Foundation Hybrid Bass System
In the Von Schweikert way, the 800-watt Foundation amplifier powers the woofers. Unlike other active DSP designs, the full range of the signal passes entirely through the analog crossover network. This allows the tonal characteristics of the customer’s preferred power amplifier without compromise yet offers the increased dynamics and precise adjustment of your in-room bass response. Whether you prefer the sound signature of a medium power tube amplifier or a high power solid-state unit, no problem. The analog purity, increased power, and dynamics enhance your investment in a high-end loudspeaker.
Audio professionals and seasoned audiophiles understand the limiting factor in the performance of a system is the listening room. While some listeners have the luxury of a dedicated room outfitted with expensive and often ineffective room treatment, most do not. Within the spectrum of room acoustic challenges, speaker placement is dictated mainly by specific room bass modes activated by the speaker within a room. As a result, audiophiles traditionally place their speakers well into the room to mitigate this problem. It should be noted that irregular bass output caused by the room significantly affects middle and high frequencies with overall tonal balance.
The Foundation Hybrid Bass System allows listeners to locate their speakers where they look and sound best. This flexibility and exceptional room optimization tool is accomplished in a completely analog mode without the use of digital signal processing eschewed by purists because of its potential to introduce time and phase distortions and without affecting the performance of the main system amplifier.
This speaker model can be built as fully passive, or as an optional upgrade with the Foundation Hybrid Bass System.
Triple-wall Quiet Cabinet
Developed in 1994 by Albert Von Scheweikert in association with lab partners from Cal Tech, Von Schweikert cabinets are fabricated using a proprietary triple-wall laminate construction technique. Despite inventive efforts by other makers using aluminum and sheet extruded composites, this triple-wall method remains the gold standard of non-resonant enclosure design.
Our quiet cabinet design’s outermost layer uses a resin-based HDF (high-density fiberboard) sheet. The middle layer is made of synthetic stone adhered to the outer layer using a resin binder. The final layer is a dense woven damping material. The resulting triple-wall composite is approximately three inches in overall thickness. Once the cabinet is assembled, internal bracing is added so that various areas of the cabinet have varying stiffness levels. The elaborate construction techniques combine to create differing native Qs, working together as a symbiotic system of resonance-cancellation to efficiently turn unwanted energy into heat for the absolute best in cabinet vibration control.
Rear Soundfield Creation
Albert Von Schweikert’s earliest research led to the development of an adjustable ambiance retrieval system radiating from the speaker’s rear to recreate a natural soundfield of space & depth using a concert hall recording method known as the spaced omni method. This system replicates the effect when microphones used for recording encode the musical signal with overlaying pickup response patterns.
After studios make a series of recordings using several different microphone types, the playback from each device has tonal differences and create various imaging patterns. This creates a differing perception of space & depth dependent on the recording environment, microphone placement, and each microphone’s distinct off-axis polar response. From this framework, our rear soundfield system creates a natural soundstage, regardless of the recording, microphone type, and recording technique used. Most importantly, the system allows the playback response to remain as close as possible to what was intended by the engineer.
Drivers & Crossovers
For our midrange and bass drivers (exclusive of the sub-bass drivers found in our ULTRA.nine, ULTRA.eleven, and SHOCKWAVE subwoofer series), Von Schweikert has selected Accuton of Germany’s drivers manufactured using ceramic cones. Producing drivers made from Al²O³ hard ceramics offers an incredibly light, stiff cone with high internal damping. Ceramic cones also offer our engineers a mass/stiffness ratio surpassed only by cones made of beryllium and diamond, which are materials that most often are only suitable for smaller diameter drivers used for reproducing high frequencies, such as tweeters Ceramic drivers offer us the best impulse response and significantly reduced distortion over more conventional drivers, as well as we as increased bandwidth and linearly within their useable range. Industry professionals recognize VSA as one of the most experienced and best practices for using these extraordinary drivers.
For the highest frequencies, we have selected the best Danish beryllium tweeters. Our chosen beryllium tweeter is extremely stiff and light. It has high power handling, exceptional detail, and superb dispersion across its usable range. While many associate beryllium tweeters with a certain sterile sound, by correctly applying our proprietary crossover network topology to this remarkable driver, the opposite is true. In short, the VSA beryllium tweeter offers some of the finest and most satisfying high-frequency reproduction in any commercial loudspeaker, regardless of price.
Custom Cabinet Finishing
Beauty and artistry worthy of the Von Schweikert Listening Experience. Today’s high-end speakers are known for their luxurious materials, design and quality. And let’s face it, this contributes to the price and pride of ownership. Von Schweikert’s painted finishes are completely bespoke affairs, the completion of which is accomplished by a true artisan with a storied background tying in perfectly with the beauty and the emotion of the instruments we create.
Fausto Reyes, is responsible for the finish of every speakers that leaves our factory. Fausto and his team painstakingly labor by hand to apply our brilliant multi-coat finishes. While we regularly apply automotive inspired paints colors, Fausto’s process is different. The reason for this is before joining Von Schweikert, Fausto led the pro division of Fender Guitar where he oversaw the painting of custom guitar finishes for some of the most notable musicians and wealthiest collectors in the world— Prince and Aerosmith to name just a few. For those who respect and value such artistry and choose one can say truly say they own a “Fausto”.
Add to this our cabinet makers are a second generation American builder reflecting the same craft ethos who have been building cabinets in California for nearly five decades just like the Von Schweikert’s. Proudly building and creating our product in the US, we can say without exaggeration that buying a Von Schweikert loudspeaker is an investment in American craft, heritage and technology.

This creates a differing perception of space & depth dependent on the recording environment, microphone placement, and each microphone’s distinct off-axis polar response. From this framework, our rear soundfield system creates a natural soundstage, regardless of the recording, microphone type, and recording technique used. Most importantly, the system allows the playback response to remain as close as possible to what was intended by the engineer.
Drivers & Crossovers
For our midrange and bass drivers (exclusive of the sub-bass drivers found in our ULTRA.nine, ULTRA.eleven, and SHOCKWAVE subwoofer series), Von Schweikert has selected Accuton of Germany’s drivers manufactured using ceramic cones. Producing drivers made from Al²O³ hard ceramics offers an incredibly light, stiff cone with high internal damping. Ceramic cones also offer our engineers a mass/stiffness ratio surpassed only by cones made of beryllium and diamond, which are materials that most often are only suitable for smaller diameter drivers used for reproducing high frequencies, such as tweeters Ceramic drivers offer us the best impulse response and significantly reduced distortion over more conventional drivers, as well as we as increased bandwidth and linearly within their useable range. Industry professionals recognize VSA as one of the most experienced and best practices for using these extraordinary drivers.
For the highest frequencies, we have selected the best Danish beryllium tweeters. Our chosen beryllium tweeter is extremely stiff and light. It has high power handling, exceptional detail, and superb dispersion across its usable range. While many associate beryllium tweeters with a certain sterile sound, by correctly applying our proprietary crossover network topology to this remarkable driver, the opposite is true. In short, the VSA beryllium tweeter offers some of the finest and most satisfying high-frequency reproduction in any commercial loudspeaker, regardless of price.

ULTRA.eleven
ULTRA.eleven
The ULTRA 11 achieves a level of performance and realism previously not possible utilizing an all-new cabinet noise reduction design, low distortion drivers and signal path, as well as our proprietary Global Axis Integration Network circuit design.
The ULTRA.eleven defines the term flagship. Completely hand-assembled and built to order, the ULTRA.eleven represents an awe-inspiring creation that only a lucky few will own. Standing eight feet tall, weighing 750 pounds, and featuring eleven individual drivers, the ULTRA.eleven is as awesome to behold as it is to listen to. Spanning the range from 16hz to over 40,000khz, the ULTRA.eleven presents effortless dynamics and natural scale with near zero distortion. Forget the technicolor presentation of many super speakers, from chamber orchestras – to symphonies – to jazz and rock and roll; the ULTRA.eleven always presents music with natural size and scale. Dual rear-mounted shockwave subwoofers powered by two 1000-watt amplifiers create a robust foundation that allows music to float on the power and majesty one should expect at this price level. While there are rivals, the ULTRA.eleven simply has no peer.
Specifications
• FREQ RESP: 16Hz – 40KHz
• SENSITIVITY: 94dB @ 1w/1m
• IMPEDANCE: 4ohms nominal
• REC. MIN. POWER: 100 watts
• SIZE: 84″ x 21″(rear) x 30″
• CRATED: 94”x29”x43
• FOUNDATION HYBRID BASS AMPLIFIER: 1200 watts R.M.S. (optional upgrade)
Foundation Hybrid Bass System
In the Von Schweikert way, the 800-watt Foundation amplifier powers the woofers. Unlike other active DSP designs, the full range of the signal passes entirely through the analog crossover network. This allows the tonal characteristics of the customer’s preferred power amplifier without compromise yet offers the increased dynamics and precise adjustment of your in-room bass response. Whether you prefer the sound signature of a medium power tube amplifier or a high power solid-state unit, no problem. The analog purity, increased power, and dynamics enhance your investment in a high-end loudspeaker.
Audio professionals and seasoned audiophiles understand the limiting factor in the performance of a system is the listening room. While some listeners have the luxury of a dedicated room outfitted with expensive and often ineffective room treatment, most do not. Within the spectrum of room acoustic challenges, speaker placement is dictated mainly by specific room bass modes activated by the speaker within a room. As a result, audiophiles traditionally place their speakers well into the room to mitigate this problem. It should be noted that irregular bass output caused by the room significantly affects middle and high frequencies with overall tonal balance.
The Foundation Hybrid Bass System allows listeners to locate their speakers where they look and sound best. This flexibility and exceptional room optimization tool is accomplished in a completely analog mode without the use of digital signal processing eschewed by purists because of its potential to introduce time and phase distortions and without affecting the performance of the main system amplifier.
This speaker model can be built as fully passive, or as an optional upgrade with the Foundation Hybrid Bass System.
Triple-wall Quiet Cabinet
Developed in 1994 by Albert Von Scheweikert in association with lab partners from Cal Tech, Von Schweikert cabinets are fabricated using a proprietary triple-wall laminate construction technique. Despite inventive efforts by other makers using aluminum and sheet extruded composites, this triple-wall method remains the gold standard of non-resonant enclosure design.
Our quiet cabinet design’s outermost layer uses a resin-based HDF (high-density fiberboard) sheet. The middle layer is made of synthetic stone adhered to the outer layer using a resin binder. The final layer is a dense woven damping material. The resulting triple-wall composite is approximately three inches in overall thickness. Once the cabinet is assembled, internal bracing is added so that various areas of the cabinet have varying stiffness levels. The elaborate construction techniques combine to create differing native Qs, working together as a symbiotic system of resonance-cancellation to efficiently turn unwanted energy into heat for the absolute best in cabinet vibration control.
Rear Soundfield Creation
Albert Von Schweikert’s earliest research led to the development of an adjustable ambiance retrieval system radiating from the speaker’s rear to recreate a natural soundfield of space & depth using a concert hall recording method known as the spaced omni method. This system replicates the effect when microphones used for recording encode the musical signal with overlaying pickup response patterns.
After studios make a series of recordings using several different microphone types, the playback from each device has tonal differences and create various imaging patterns. This creates a differing perception of space & depth dependent on the recording environment, microphone placement, and each microphone’s distinct off-axis polar response. From this framework, our rear soundfield system creates a natural soundstage, regardless of the recording, microphone type, and recording technique used. Most importantly, the system allows the playback response to remain as close as possible to what was intended by the engineer.

CENTER CHANNEL
LCR-4
LCR - 4
Available in high-gloss black, the LCR-4 Loudspeaker is the perfect choice for someone looking for a full-range reference monitor solution regardless if they want one or seven channels of sound. When paired with Von Schweikert Audio’s floor-standing speakers, the LCR-4 is the best value center channel available, blends seamlessly and brings vocal intelligibility to the forefront effortlessly.
ABOUT
This monitor uses very high quality drivers designed by Scanspeak of Denmark. Since the twin 7in (178mm) bass-mids have to reproduce both the bass and midrange frequencies, it is a challenge to design a driver that will reproduce the human voice with extreme clarity, while also being asked to reproduce deep bass frequencies at a high volume level. In order to obtain the maximum vocal intelligibility, the LCR-4 uses specially designed drivers that were optimized for this function, and consist of high-tech laminated cones driven by patented Low Distortion Motors. The Scan designed 1” tweeter has a long throw, chambered rear cavity to reduce resonance, a specially treated fabric dome, and the Low Distortion Motor. This tweeter combines both high details with extremely smooth sound, especially in the important vocal range.
To ensure extreme clarity in the vocal range, we have eliminated cavity resonance by using a sealed box design, and to eliminate the cabinet wall distortion, we have utilized our Triple-Wall Noise Canceling Technology. By bonding three different materials together, included resin-impregnated MDF, artificial stone, and rubberized felt in a 2.75” thick composite, the opposing Q’s of these materials cancel the natural tendency of the walls to vibrate.In order to synchronize the bass-mids with the tweeter, we have employed our Global Axis Integration Network, a 4th order crossover slope which is phase consistent and has almost zero distortion. Since we are not pushing the drivers outside of their intended operating range, the clarity of the LCR-4 is at the state-of-the-art level, which is extremely important for vocal intelligibility in a center channel application and has no problem keeping up with our large floor-standing left and right main speakers.
SYSTEM TYPE
VSA’s engineering team succeeded in converting our proprietary Triple-Wall Noise Cancelling technology to operate in these smaller cabinets. Three different materials with opposing Q factors are used to build the cabinet walls, resulting in clarity that must be heard to be appreciated. The 65mm (2.75″) thick walls consist of 20mm resin impregnated fiberboard, 20mm artificial stone, 20mm rubberized felt, and 5mm vibration-proof adhesive layers. This cabinet wall design is superior to aluminum, plywood, or MDF, based on measurements of panel ringing.

SHOCKWAVE.subwoofer
SHOCKWAVE subwoofers are available in 10” (coming Spring 2025), 12”, and 15” sizes and feature slotted port quasi-transmission line loading. All woofers integrate perfectly into any room and any loudspeaker design, retaining the hallmark power, speed, and detail Von Schweikert speakers are known for. A light and stiff carbon fiber driver featuring a vented voice coil and massive motor is perfectly tuned to deliver response down to 12hz. Powering the system is our proprietary Foundation amplifier technology, outputting 1000 watts. The amplifier circuit features an isolation transformer, which allows us to take the signal directly from the system’s main amplifier for the purest signal tracking, lowest distortion, and zero signal delay. Phase is adjustable in either standard or inverted polarity from O-360 degrees depending on the application, for example, bass reinforcement or irregular room bass modes in the room. A new feature in Q1 2025 will allow for stacking multiple SHOCKWAVEs for the ultimate bass performance regardless of room size.
