SR-1 Owner’s Manual
If you are using the preferred method of bi-wiring with two pairs
of speaker cables from the power amplifier, then you may connect
the wire set from the amplifier to either pair of the lower cabinets
binding posts. If you bi-wire the speaker then remove the supplied
jumper wire. In either regard please keep in mind that the speaker
cabinets are polarity sensitive. The positive speaker terminals on
both pairs of speakers need to attach to the positive terminals
of the power-amplifier. The negative speaker terminals on both
pairs of speakers need to attach to the negative terminals of the
amplifier. Maintaining proper signal polarity is critical with all bi-
wired speakers. Failure to maintain consistent polarity between the
speakers and amplifier will be cause all manner of ills from collapsed
and diffuse soundstage to greatly marginalized frequency response.
It is difficult to provide absolute instructions for speaker placement;
but we can give suggestion as to good starting points. Optimal
results with the SR-1 as with most speakers are frequently achieved
with subtle changes of physical location.
The first rule however, is that the room in which you listen is perhaps
the most significant of all audio components in the reproduction
chain. Speakers can be made to work satisfactorily in poor sounding
rooms, but it is much easier to achieve success in an acoustically
correct room.
The ideal room is neither overly reflective nor overly absorptive.
In a good sounding room, the absorptive elements tend to be at
reflection points of the sidewalls, floor, ceiling and space behind the
speaker. High ceilings or at least absorptive ceilings lend themselves
to more natural sounding spaces. Diffusion generally is a good thing
and excellent listening rooms typically have diffusion in abundance.
Great sounding rooms are either large enough or absorptive enough
to discourage strong standing waves in the listening area. Good
sounding rooms that present a proper spatial image tend to be very
symmetrical in layout, left to right.
