The very high current input terminals located on the rear of your Cub loudspeaker
are color coded with a small plastic plug, so that RED corresponds to positive and black to
negative, common, or ground on the amplifier output. Be sure to connect the loudspeakers
in phase with each other. We recommend the use of the very highest quality loudspeaker
cables, particularly those designed for high frequency propagation correction and phase
linearity. Beware of “zip cord” type speaker cables which will smear the sound from your
Cubs, and limit their effective bandwidth. Also, do not use braided litz type loudspeaker
cables as they will cause an unnatural brightness to the sound, compromise sound staging
performance, and may cause instability, oscillation and damage in wide bandwidth solid
state amplifiers.

The spade lugs of some of the high quality cables often used with the Cub are angled
to reduce pressures on the cable during installation. Avoid the instinct to push the cable’s
spade lug ends all the way into the Cub’s connectors (see Figure 6 ). Partial insertion of
these angled spade lugs will actually improve the reliability of the connection. Flat lugs may
be fully inserted to connectors before tightening.
