Placement

HORIZONTAL BI-AMPING: If two different stereo amps are available, one amp can drive the woofers and the other amp, perhaps of lower power, can drive the M/T’s. This works well with large solid state amps driving the woofers, with a smaller tube amp driving the upper end. We have heard of systems with 200 watts per channel on the woofers, with 20-30 watts per channel of tube power driving the M/T sections. This may seem like an imbalance, but since the most power is needed to drive the woofers, it will work very well!

The VR-5 Anniversary are Room Interactive, meaning that they were designed to work in an average listening room, not an anechoic chamber. Speakers that measure very good in an anechoic chamber will usually sound too bass heavy and directional when placed in a room due to boundary effects and room gain in the bass region. The increased bass response of the room (called boundary gain) has been factored into the VR-5’s tonal balance, along with the reflective nature of boundary surfaces such as wood, plaster, glass, and so forth. Since the VR-5’s are quasi-omnidirectional transducers, designed to be the inverse of the recording microphone, their sound output will react with the listening room in a positive manner only if properly placed. There are two components of sound which reach the listener’s ears:

1.The direct arrival, or initial wave-launch of the speaker itself; this is the sound that is purely from the speaker system and should be dominant in your room.

2.The secondary waves which are reflected from the room’s boundary surfaces. The reflected sound is delayed according to the distances involved from the speaker to the boundaries, then back to the listener. It is important for the reflected sound-field to integrate properly with the initial wave-launch, since out-of-phase reflections will interfere with both flat frequency response and image focus. It is not difficult to determine where the best placement will be in any given room, since you will be using a pink noise listening test discussed later. (See Pink Noise Test on Page 8).

In every room, there will usually be more than one magic spot for the VR's to sound their best. However, finding those spots is not intuitive due to the nature of reverberation characteristics and room dimensions, which vary enormously from room to room. The VR's, being Virtual Reality simulators, are designed to load the room very similarly to the way a live instrument would load the room. Only in this way can your ear/brain hearing mechanism be lulled into believing that you are listening to an actual performance, and not simply “canned” sound. If you had a grand piano at the end of the room where the speakers are playing, it would involve the entire room with semi- omnidirectional sound, and your ear/brain hearing mechanism will clearly know this. The VR Virtual Reality design will simulate this huge sound-field, with it’s involving depth and dimension. However, correct placement is required to achieve the best possible sound quality. Amazingly, moving the speaker only a few inches can make the difference between good sound and great sound due to the reflective properties of your room! Note that this fact is true with most high quality speaker systems.

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.
