CARE FOR THE FINISH....................PAGE 15 INTRODUCTION Thank you for investing in a Virtual Reality speaker system designed by Von Schweikert Audio. Used properly, the VR-5 Anniversary model will give you many wonderful years of exciting musical reproduction, closer to the emotional truth of the composer, performer, and producer’s intent. In order to fully benefit from the VR-5's powerful magic, please read the following instructions thoroughly. -
Page 3: Important Notes
Do not discard the boxes or otherwise alter the contents, as the inspector will want to see the damage as you found it. Since Von Schweikert Audio has no control over the shipping companies or their damage claim policies, it is imperative that you follow the instructions from the freight company agent explicitly. -
Page 4: Initial Setup
SETUP 1. Please do not install the spikes until the proper placement has been determined. If you try to move the speakers around with the spikes installed, you can damage your floor and/or rip out the spikes, so please be careful and install the spikes only when you are confident that the speakers have been placed in the proper position. - Page 5 the best image focus and widest sound stage. However, since your taste may vary, you may well prefer the extra depth achieved with no toe in; i.e., the speakers parallel to the side walls. ON SHORT WALL: Placing the speakers on the short wall and sitting far back in the long end of the room may give you a concert hall experience if your room is large.

Page 6: Wiring
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. -
Page 7: Bi-Amping
RCA plugs and binding posts for best results. Contact cleaner/treatments increase the sweetness, air, soundstage depth, and smoothness to an amazing degree, try it! RECOMMENDED CABLES BY VON SCHWEIKERT AUDIO Since most wire companies do not have engineering experience with our bi-wire design, we have spent four years designing the best possible speaker cables for our customers. -
Page 8: 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. -
Page 9: Pink Noise Test For Focus
crossover circuit, which achieves the desired phase-consistent sound field over a wide listening area. If you must situate the speakers close together, with a close listening position for near field applications (such as in a recording studio), you may not need to toe the speakers in towards you, but you will need to sit with your ears on the tweeter’s vertical axis for flattest frequency response. -
Page 10: Rear Ambience Driver
pink noise “ball.” If your former speakers were placed close together to achieve center fill, try spreading the VR-5’s further apart. Their wide dispersion enables a larger sound stage. *Note: if the speakers can not be separated more than a few feet due to room considerations, as in a video application, it may be necessary to toe the speakers outwards in order to gain a wide sound stage and reduce the tendency towards monophonic image focus. -
Page 11: Woofer Tuning/Bass Response Adjustments
BASS RESPONSE TUNING BACKGROUND INFORMATION: Since enclosed rooms will affect the bass response due to standing wave formation, a woofer tuning feature has been designed into the VR series of speakers. Deep bass in the 20-40Hz range is highly desirable in a reference speaker design, since hall reverberation at low frequencies is a sonic clue to both depth and hall size. - Page 12 of the front wall, rear wall, side walls, and the floor. These reflections both reinforce and cancel the original direct wave, depending on the wave length vs. the path length. If the path length is an even multiple of the direct wave at any one given frequency, the reflection will reinforce the first wave since it will be mathematically additive and will cause a peak in the response at this frequency.

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. -
Page 14: Trouble Shooting
TROUBLE SHOOTING Your VR dealer should have the necessary resources to investigate any problems you may experience when setting up a world class reference system. However, if you find that you need specialized help, either in acoustical or electronic interactions not well understood by your dealer, please don’t hesitate to contact the factory by emailing your request to: albert@vonschweikert.com. -

which are the boundary surfaces halfway between the listener and the speaker cabinets. This includes the ceiling, walls, and floor. Hard plaster ceilings will reflect treble energy back down towards the listener, and should be treated with acoustic tiles (the soft and porous type) or damping pads made from foam or fiberglass.
