CARPETED FLOORS: Install the spikes after break in – this is easily accomplished with two people, one tipping the speaker back while the other installs the spikes. Be careful not to let the M/T unit fall off the woofer module! If one person installs the spikes, remove the M/T modules before attempting to install the spikes. Make sure that you level the speakers so they don’t rock, and use the locking nuts to make sure the spikes won’t vibrate loose. You will be amazed at the improvement to both the bass response and the image focus after installation of the spikes.

WIRING

The VR-5 system was designed to accept bi-wire speaker cables, so you will find two pairs of binding posts on the back of each speaker system: one pair on the woofer module and another pair on the midrange/tweeter module. See below for information on what bi-wiring can do for you.

SINGLE CABLE:

Connect the speaker cable to the binding posts on the upper midrange/tweeter unit, then connect a “jumper” wire to deliver the signal downwards to the woofer module. You can have a jumper wire constructed from the same type and brand of speaker cable that you are using, contact the manufacturer of the cable. If this is not an option, then use a piece of high quality speaker cable to connect the binding posts together, using the bare wire ends inserted into holes in the side posts of the binding posts. If you wish, you can solder banana plugs onto the jumper wires for a cleaner fit.

NOTE: we recommend using this only as a temporary solution, as we designed the speakers expressly for bi-wiring. DO NOT connect the main speaker cable to the woofer module, as you will be able to hear a loss of clarity in the midrange and treble frequencies due to extra connections in the signal path and the effects of the jumper wire.

BI-WIRING: This is the recommended wiring mode and VSA now offers speaker cables designed expressly for bi-wiring our speaker systems. Please email for information and prices.

THEORY OF BI-WIRING:

Using two separate pairs of speaker wires to deliver the signal to the woofer and midrange/tweeter modules will result in superior image depth, cleaner upper midrange/treble, and a larger sound stage. These benefits are due to the isolation of the powerful bass signals from the more delicate treble frequencies as the signal travels up the speaker cables. Since there is generally ten times more voltage present in the bass signal, the generation of a magnetic field in the positive and negative conductors will interfere with the more delicate treble signals. This magnetic modulation is easy to hear on a high resolution speaker like the VR-5 Anniversary but may not be as audible on lesser speakers. Using two separate conduction paths will enable the bass frequencies to be separated from the treble frequencies due to the high impedance “seen” by the signals due to the internal crossover networks. In other words, since there is a “high impedance” (to low frequencies) in the midrange/tweeter crossover, bass frequencies WILL NOT travel from the amplifier up to the midrange/tweeter unit, even though both speaker cables are connected to the same binding posts on the amplifier! The opposite effect occurs in the woofer cables, where no midrange/tweeter frequencies will travel due to the high impedance “seen” as the result of the woofer crossover. Crossover filters work due to the reactances supplied by the inductors and capacitors; inductors generate a “high impedance” to midrange/treble frequencies

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.
