The LFT-8b is configured to allow bi-wiring or bi-amping with a

minimum of trouble.

Bi-wiring simply means connecting a single stereo amplifier (or two

mono amps) to a pair of speakers by using two pairs of speaker cables.

Connect the hot and ground conductors of a pair of cables to the same

output terminals on one channel of the amplifier; the other ends are

connected to the separate woofer and mid/tweeter inputs of the LFT-8b

(All speaker cables should be the same length). The effects of bi-

wiring tend to be subtle; the slight improvement may be worth the

relatively modest cost of an extra pair or speaker cables. Bi-wiring also

permits experimenting with different types of cables for the two inputs;

you may find that one type is best suited for bass performance, while

another works best on the mid/treble side.

Bi-amping requires and additional stereo amplifier or pair of mono

amps. You will also need some means of insuring that only the desired

portion of the frequency range reaches each amplifier. The simplest

way to accomplish this is with an external electronic crossover;

however, this can also be done by hard-wiring low-pass and high-pass

filters into the inputs of the bass/mid and treble amplifiers, respectively.

For the low/ frequency amp, a 180Hz low-pass filter (6 dB/octave) is

required; for the mid/treble amp, a 180Hz. high-pass filter (also 6

dB/octave) is required. If you wish to pursue this method, your dealer

or the manufacturer of your amplifiers should be able to help you

determine the specific parts necessary. Note that you will also need a

level control on either one of the stereo amps or on the crossover,

regardless of which approach you take to bi-amping. Contact Eminent

Technology or refer to the schematic in the back of this manual to

modify the crossover for proper speaker operation.
