Von Schweikert Audio Presents:

The all-new VR-44 Speaker System

We are proud to announce the most significant change to the VR-4 platform in over a decade.

Although the VR-4 was one of the most highly regarded and trend-setting designs of the 1980’s up until today, we found room for improvement in several key areas, even though the 17 reviews of this model over the years have been “raves.”

Resolution, transparency, and room adaptation were the focus of our R&D program over the past few years, leading to a new cabinet resonance-control design. Our new Triple-Wall Laminate (Pat. Pend.) utilizes three different types of materials bonded together, which resonate at different frequencies and “Q” levels, effectively eliminating the cabinet as a source of coloration. No need to spend tens of thousands of dollars to buy an aluminum-bodied speaker system, as our Triple-Wall design is superior at a fraction of the price!

As high resolution digital music files redefine the level of clarity now available to the audiophile, we found it necessary to update our transducers to provide a far higher level of detail, transparency, and “presence.” As any good scientist knows, a speaker diaphragm must be extremely light and rigid if accuracy to the signal is desired. It is difficult to imagine that a cone needs to stop and start 2,000 cycles per second to reproduce a female vocalist’s voice when she hits a high note!

However, since many types of rigid cones made from ceramic or metal materials have a tendency to “ring” and sound harsh in the upper midrange, it is imperative that the cone have high internal damping to eliminate ringing. For this reason, our European engineering partners have helped us design a complete transducer set that is matched to each other in transient response speed and low distortion, using a highly damped cone with linear frequency response.

Our new cone technology is based on laminating different types of materials to provide stiffness without the penalty of ringing. Our new 6” full-range driver cone is made of composites of cellulose acetate pulp, acrylic plastic, and carbon fiber, while the tweeter is a similar organic material with a soft plastic coating. To provide extreme rigidity, our new 8.8” woofers are formulated from ceramic-coated alloys of magnesium and aluminum, which is damped with a layer of electrostatically applied oxide powder. Since the twin 8.8” woofers are crossed over to the full-range driver at 100Hz, the woofers are not audible as a separate source of sound; the full-range mid drivers are dominant.

To ensure that the drive units sound coherent, we have selected crossover points far below and above the midrange frequencies, at 100Hz and 4kHz. All crossover parts are world-class, such as our Mundorf resistors and capacitors, Delphi Aerospace wiring, and WBT posts. The cabinet baffle tilts backwards for Time Alignment and we have taken special attention to the phase alignment of the new driver array. The image focus and 3-D layering has to be heard to be believed!

To enable this model to work with any amp, in any room, we have provided an optional powered sub-woofer system that can enable a small tube amp with only 20-watts to drive the VR-44 as if the amplifier has 200 watts. You will hear Dynamics!



System Type: Three-way dynamic cone system using Quasi-transmission line technology for tight, deep bass response. Wide dispersion design.

Cabinet Design: Exclusive Triple-Wall Laminated panel design, with thicknesses ranging from 1” to 3” using High Density Fiberboard, plasticene damping, and artificial stone blocks. These three materials have “opposing Q’s” which cancel each other out, since they resonate at different frequencies.

Bass Tuning: The twin woofers are mounted in a four-chamber labyrinth, where each chamber is filled with a specific quantity of crimped Dacron. The rear-mounted exit port is tuned to 20Hz.

Midrange Loading: The 6” full-range driver is loaded into a sealed labyrinth, using Gradient Density stuffing to gradually absorb the rear wave.

Tweeter Loading: The Wide Surround, dual-ring tweeter has an open back, loaded with a plastic cup filled with highly absorbent material. The free air resonance of this unit is 540Hz!

Ambience Retrieval System: In order to simulate an omni-directional recording mic, we have designed a rear-firing midrange-tweeter, fed by an ambience-extraction circuit with Level Control. This provides an amazing sense of depth and a “bubble” of sound to radiate spherically from the cabinet.

Crossover Design: Since the transducer set has been engineered to work together without any negative interactions, the crossover network is a simple circuit that utilizes the best parts available. The goal was to provide a “direct” signal path and have a very low level of phase shift. Mundorf of Germany supplies us with the resistors and capacitors for this circuit.

Crossover Points: 100Hz and 4,000Hz due to the Wide Band full-range drivers used as a midrange.

Drive Unit Sizes: Two- 8.8” composite alloy woofers, one-6” composite full-range driver used as a midrange, and two-1” tweeters, one in front and the second at the rear. Rear unit is horn loaded.



Frequency Response: 16Hz to 40kHz, +/- 6dB, 20Hz to 30kHz +/- 3dB (1 dB in midband).

Impedance: 4 ohms with 3-ohm minimum (Passive Version). Aktive version is 8-ohms.

Sensitivity: both Aktive and Passive are 90dB @ one watt/one meter.

Power Rating: Minimum of 20-watts up to 500-watts. If you own a 10 to 30-watt tube amp, we recommend the Aktive Version. If you own any amplifier with 50 watts or more, the Passive Version would work very well, unless you like having a volume control for the bass level.

Dimensions: 41” tall x 13” wide at bottom and 9” wide at top, with 27” depth due to heat sinks.

Weight: 151 lbs without the shipping crate, 236 lbs with the shipping crates (per speaker).

Available Finishes: standard are Steinway Piano gloss black and Mercedes Platinum Silver. Other automotive finishes are available at extra cost.

Available Models:

Passive Version: no amplifier included for woofers. This is the model to buy if you have a large, powerful amplifier that has plenty of bass power.

Aktive Version: 300-watt r.m.s. (600 watts peak) amplifier built in, to drive the twin 8.8” woofers from 16Hz to 100Hz. Volume level is provided for adjustment for any room or listening taste. The amplifier accepts the output signal from the customer’s main amplifier, thus no RCA cable is required, nor is an electronic crossover needed.

Room Sizes Recommended: Any size room will work well due to the adjustable bass.

Warranty: Five years on cabinet, transducers, crossover, and build quality. Three years on amplifier in the Aktive version.

Warning: Seat belts may be required to keep you from falling out of your listening chair.
