Lack of Apparent Bass | Von Schweikert Audio VR-5 specs

B). If the frequency range between 20-30Hz sounds too powerful in your particular room, simply place a large handful of the Dacron in each vent tube; this will lower the efficiency of the vent tuning. If the bass is still too loud, place another handful in each vent.

If the low frequency range has come into proper balance, stop there. If you change locations, you can always remove the balls of Dacron by reaching into the vent.

BASS RESPONSE TUNING FOR TUBE AMPLIFIERS:

Since tube amplifiers have “air and liquidity” in the mid and treble ranges, many audiophiles use them. However, the saturation, back EMF, and transient response delays caused by the output transformers may cause sluggish bass response which can be heard when using any speaker that has response below 30Hz. The deep bass can be tightened considerably by the addition of several handfuls of Dacron in each vent which is then pushed into the enclosure. It is possible to tighten the VR-5's bass response to a degree not heard with other speaker systems, so don’t be afraid to experiment!

LACK OF APPARENT BASS:

In some rooms, especially those with “soft” walls such as wallboard over studs, open floor plans, and rooms with poor dimensional ratios, it is possible to “lose” bass response. Also, when sitting in a “null,” it is possible to perceive, incorrectly, that there is a lack of bass power in the speaker system itself. In these cases, it will be necessary to move either the speaker position or the listening position in order to optimize the response. By playing a recording with a repeating bass line, try walking around the room until you find the places where there is apparent bass. It will be necessary, in some cases, to reposition the speakers in order to allow the room to boost the bass by using the natural “gain” of the boundary reflections. Simply move the speakers closer to the rear wall or side wall in small increments until the bass sounds right.

ANCILLARY EQUIPMENT

The VR-5 Anniversary is far more transparent than any other competing design, including electrostatics. (If you don’t believe this, put any electrostatic next to the VR-5 and use a transparent switching device such as a copper knife switch to directly compare the sound of the VR to the electrostatic. Make sure that you use the same channel, since the electronics may have a large difference in sound between the channels, and the same brand of cable. It may be necessary to use a metal film resistor to equalize the sensitivity of the louder speaker in order to make a fair test.) Here at the factory lab, we have used several brands of electrostatic and ribbon speakers for comparison and have been consistently amazed at the results we are achieving with dynamic cone drivers!

Since the VR design is quite transparent, without audible coloration and distortion, it is necessary to use only the finest sounding equipment available to drive the VR-5's. This does not mean you must purchase the most expensive gear, just good sounding electronics, especially in the front end. Many digital products have limited depth and excess treble brightness caused by overemphasis of harmonic structure. The VR’s will enable you to easily hear the differences even between digital cables, which theoretically, should have no sonic signature! Any sonic qualities you attribute to the VR's are actually coming from the chain preceding the speakers. When using neutral driving equipment, the VR-5’s will be found to have virtually no sound of their own!

VR-5 specifications

The Von Schweikert Audio VR-5 stands as a true testament to high-fidelity audio engineering, attracting audiophiles with its impeccable sound reproduction and innovative design. This loudspeaker is part of Von Schweikert's acclaimed VR series, consistently lauded for its advanced technology and precision craftsmanship, which together create an immersive listening experience.

At the core of the VR-5's design is its unique three-way, four-driver configuration. This setup includes a large woofer, a midrange driver, and dual tweeters, each meticulously engineered to deliver a specific frequency range. The woofer is designed to produce powerful bass, capable of extending well into the lower frequencies, while the midrange driver excels in rendering vocal clarity and scale. The dual tweeters ensure that high frequencies are crisp and detailed, providing a sense of airiness and openness to the overall soundstage.

One standout feature of the VR-5 is its proprietary V-Frame design, which minimizes resonances that can color sound. This design innovation, combined with high-quality materials, lends the speakers superior structural integrity, ultimately resulting in more accurate audio playback. The use of advanced cabinet construction techniques, including extensive internal bracing, ensures that unwanted vibrations are kept at bay, allowing listeners to experience music as it was intended.

Additionally, the VR-5 incorporates advanced crossover networks that contribute to seamless integration between drivers. These crossovers employ state-of-the-art components designed to preserve signal purity and maintain phase coherence, further enhancing the fidelity of sound reproduction. The result is a coherent sonic image where instruments and vocals occupy defined positions, enriching the spatial characteristics of any recording.

Another key characteristic of the VR-5 is its ability to adapt to different room acoustics. Featuring adjustable rear bass ports and a customizable crossover frequency, users can fine-tune the speaker’s performance to suit their specific environment. This flexibility ensures that audio enthusiasts can enjoy an optimal listening experience, regardless of their space.

In summary, the Von Schweikert Audio VR-5 is a highly regarded loudspeaker that brings together state-of-the-art engineering, innovative design, and sophisticated technologies. With its three-way driver configuration, robust construction, advanced crossover networks, and room adaptation capabilities, the VR-5 offers an exceptional listening experience for even the most discerning audiophiles.
