3 Please read the following instructions regarding s etup, as imaging and bass response must be optimized to y our particular room. Since every listening room will have different di mensional ratios and reflective/absorptive coefficients, each setup will be different. A th orough break-in must be conducted in order to realize the ful l benefits of [...]

If you try t o move the speakers aro und with the spi kes installed, you can damage your floor and/or rip o ut the spikes, so please b e careful an d instal l the spikes o nly when you are confident that t he s peakers have been pla ced in t he p roper p[...]

Be careful not to l et 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 su[...]

7 WOOFER MODULE BI NDING POSTS: Note that two pairs of binding posts are offered on the woofer module, and a re ge nerally connected together with the metal straps provided when only one cable is to be used. These two pairs of binding posts on the woofer m odule enable a “quad” cable hookup for bi-wiring – t his setup requires the use of the [...]

8 Balancing of the volume levels when using amps with different input sensitivi ties can be accomplished by outboard level controls available from your dealer at very modest cost. I f the amplifiers have input sensitivities which are fairly close, even if they are different b rands, there wil l be no need for level controls. VERTICAL BI-AMPI NG: If[...]

Ho we ver , correct placement is required to achieve the best possibl e sound quality. Amazingly , moving t he speaker only a few inches can m ake t[...]

10 curtain of sound between them, your room’s reflections and/or seating distance is destroy ing the coherent sound that was engineered into the VR design. To eliminate this unwanted effect, you will need to determine whether the room’s reflections are at fault, or whether y ou are not in the “sweet spot.” To find the focal p oint of the VR[...]

11 BASS RES PONSE TUNING BACKGROUND INFORMATION: Sinc e en cl ose d ro oms will a ff ec t the bass res pon se due to stan din g 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 [...]

Although the first arriving bass wave will have flat frequency response, fractions of a second l ater the same waves have bounced off of the f ront wall, rear wall , side walls, and the f loor. These reflec tions both reinforce and cancel the original direct wave, depe ndi[...]

Do this in both speakers, and if one handful is not sufficient to reduce the overall bass level, cont inue t o place Dacron balls upwards into the woofer cavity . B).

14 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 us ed several brands of electrostatic and ribbon speakers for comparison and have been consistently amazed at the results we are achieving with dy namic cone drivers!

15 most wear t o t he electronic components in an ampli fier results from the inrush of current from the wall into a cold p art. Once the unit is left on, the voltages and t emperatures stabili ze, resulting in better so und and compon ent life. The electric bill will not reflect a huge price difference, as electronics at idle do not use much elect[...]
