B. Selecting Speaker Wire
We recommend the following gauge of standard two-conductor wire for the
wiring distances specified; if you prefer you can use thicker (lower-gauge)
wire.
Under 25 ft «7.5m)
25 - 50 ft (7.5-15 m)
50 - 100 ft (15-30 m)
Over 100 ft (>30 m)

Connecting In Phase
Connect speakers identically to your amplifier or receiver on each
channel-Red amp/receiver terminal to Red speaker terminal, Black to
Black. This will ensure that the diaphragms of the speakers on both channels
move forward and backward together ("in-phase"), rather than in opposition
("out-of-phase"). In-phase connection provides maximum clarity and bass,
while out-of-phase connection results in frequency cancellations and
produces thinner and less distinct sound-with less bass, vague vocal quality,
and no solid centre image. To help insure the proper connection, the two
separate conducting wires in a standard two-conductor speaker cable are
coded in one way or another to be distinguishable from each other. (The
jacket of one wire may be ribbed or marked with "+" signs, or one wire under
the insulation may be a different colour from the other.) Use this wire-coding,
together with the amp/receiver and speaker colour-coding, to be sure you are
connecting the same wire of a given pair to a like-coded terminal at both ends
of your connection.

D. Be sure all wiring terminals, are tightened firmly secure, but be careful not to
over-tighten and damage the connectors.
E. Bi-wiring and Bi-amping (Alpha T1 only)
The metal jumper strap that connects the two sets of terminals on some of our
speakers is removable. This allows you to connect either separate cables to
