Von Schweikert
VR-S/1 High Speed Mini-Subwoofer
Retail Price: $1695.00
Not
just another subwoofer!
Sure, there are plenty of subs out there, if you don't care about clarity! It's quite simple to generate a lot of noise on explosions, but when your sub makes a kettle-drum roll sound like a train going by, your system is going to sound muddy! The Von Schweikert VR-S/1 High-speed Subwoofer was designed to react as quickly as any main speaker on the market, with the lowest levels of distortion and hangover, enabling the VR-S/1 to completely integrate with your system.
The VR-S/1's high speed and low distortion was achieved by engineering a very specialized woofer combined with an amplifier that is pre-programmed with the required response target. As an extra benefit, the cabinet size has been greatly reduced with our new technology.
HEROIC WOOFER
Fast, clean sound requires a very stiff cone that cannot flex and add distortion, a very powerful motor, and a suspension system that will not allow the woofer to continue ringing after the note has ended. We have selected a very strong carbon fiber impregnated resin for the cone, driven by a large 70mm voice coil. The 15- pound magnetic assembly can accelerate the cone with very high Force Factor, requiring an extremely stiff suspension to provide mechanical braking. To enable high volume levels at 20 Hz, we have utilized a very long throw design with 1.5" peak-to-peak excursion potential. The end result is a beefy driver that can provide very high volume levels of extremely clean sound!
PRE-PROGRAMMED
AMPLIFIER
Our design target was to achieve very fast transient response combined with electromechanical braking of the driver in between notes; in addition, a 20 Hz frequency response was specified for this design. These requirements dictated electronic pre-equalization, which also compensates for the small volume of air inside the cabinet. To enable very high output levels at low frequencies, we specified a High-Current amplifier with 300-watt r.m.s. and 600-watt peaks. The design is a push-pull Darlington circuit with high bias into Class A operation in the preamp stage; to eliminate distortion on peaks, a High Current power supply with 1 KV transformer is utilized.
CABINET DESIGN
To enable total room bass envelopment, we utilized a sealed cabinet with down-firing woofer. The 25mm MDF cabinet walls are damped by a shelf brace at the midpoint of the wall, stiffening the cabinet to eliminate resonance and coloration. To eliminate cavity resonance, Dacron is used at 100% stuffing density. Two-inch tall spikes elevate the down-firing woofer off of the floor, enabling 360-degree dispersion, which helps reduce standing waves by providing differing path lengths to the room boundaries. In the event that the VR-S/1 is to be used inside a wall unit, it can be placed on it's side, with the woofer firing forward. As the woofer is not visible, the cabinet has a very clean appearance and is finished in a variety of hardwood veneers with polyester resin clear coat.
SPECS:
- System Type: Powered High-speed mini-subwoofer with electronic crossover. System Q=1.
- Cabinet Design : Sealed enclosure with 25mm MDF walls, using shelf bracing to eliminate cabinet resonance and coloration; cavity resonance is eliminated with 100% Dacron stuffing.
- Woofer : 10" Extreme-Duty driver with very stiff cone formed from carbon fiber impregnated plastic resin, which is suspended by a double-thick butyl rubber surround with long-throw design (1.5" peak-to-peak excursion potential). The 70mm voice coil is aligned in the gap with a double-thick spider and is driven by a 15-lb magnet assembly to provide an extremely high Force Factor. The suspension compliance has been designed to provide a very high degree of mechanical damping to prevent oscillation and overhang between musical notes. Power handling is enhanced by rear vented design and high temperature voice coil wire, enabling 600-watt peak program material.
- Amplifier : High Current design with Darlington push-pull circuit and 1 KV regulated power supply. High bias Class A operation in the preamp section, Class AB output section. A.C. power is switchable between 117V and 230V. CE approved for Europe. Removable IEC heavy-duty power cord, auto shutoff with green/red LED.
- Output Power : FTC rating of 300 watts r.m.s. continuous with 600 watt peaks. Distortion : Less than 0.8% at full output.
- Input Impedance : 22 k Ohms.
- Input Sensitivity: 150 mV.
- Electronic Crossover : Adjustable from 40 Hz to 100 Hz with 12 dB/Octave slope with bypass switch to disengage the internal crossover when used with a multi-channel processor.
- Signal to Noise Ratio : 85 dB.
- Frequency Response : 20 Hz to 100 Hz, +/- 2 dB.
- Inputs : Stereo RCA jacks for processor, hi-level inputs and outputs with five-way binding posts.
- Controls : Volume level, Crossover frequency 40 -100 Hz, Phase reversal 0-180-deg, Crossover bypass switch, A.C power on-off. Auto shut-off with red/green LED.
- Size: Price: 13" Tall on spikes 11" Wide 15 3/4" Deep with fins

About Von Schweikert Audio
Von Schweikert Audio was founded by legendary speaker designer Mr. Albert Von Schweikert. A CALTECH trained speaker designer with a focus in Electrical Engineering he has over four decades in speaker design and is widely regarded in the industry as one of the pre-eminent speaker designers in the world. Companies such as Disney, Steinway, A&M Records, Sheffield Sound Labs, Mobile Fidelity and JVC have all sought Mr. Von Schweikert for his expertise in superior speaker design.
As a kid, he built his first speakers from kits, and modified stock drivers. He studied violin and piano, played electric guitar and worked on Time Delay Spectrometry with the famed Richard Heyser at the California Institute of Technology. While at CALTECH in the 70's, he delved into computer-based development of speaker design and psycho-acoustics, where he gained new understandings of sound radiation and how this was perceived by the listening audience.
After he left CALTECH University he worked with numerous different audio companies and was responsible for quite a few, and sometimes very spectacular speaker designs. He was in charge of more than one hundred projects, and while many of them don't display his name, most were very well known companies. As one of the world’s most experienced speaker designers he's worked with Bose, JBL, ESS / Heil, Eggleston, Apogee, Cerwin Vega, Counterpoint, Jensen, NHT and many others.
In the mid 90’s Von Schweikert Research moved the whole operation from the West Coast to Watertown, New York. The business enjoyed strong growth there until in 1999 a large flood destroyed most of the company. Financially strong investors urged the company to move back to California where "Von Schweikert Audio“ – abbreviated as VSA – was founded.
VSA has speakers in current production that range from $1,000 to $150,000 and the current product line-up includes nine models: from the compact VR-1 up to the monstrous VR-11. Center and surround-speakers and also several subwoofers top off the line for home cinema lovers. With an expansive global dealer base, the company has been enjoying strong and continuous growth while still pioneering innovative new designs and technologies for accurate and realistic sound reproduction.
With over 30 industry awards and a veritable "Who's Who" of famous clients, Von Schweikert Audio is THE speaker of choice for those who demand the world's very best.
