CONNECTIONS—ESL/TRANSITION TOWERS
Bi-Wire Connection
This method of connection uses individual runs of speaker wire from your amplifier. This doubles the signal carrying conductors from the amplifier to the speaker, thus direct- coupling each portion of the crossover to the amplifier.
Connect one set of wires to the upper set of binding posts which connect to the ESL panel of the Statement e2. Then connect a second set of wires to the lower binding posts which connect to the transitions tower. Next, connect both sets of wires to the appropriate terminals on your ampli- fier. Please take care to connect both (+) wires to the
(+)amplifier terminals and both (-) wires to the (-) amplifier terminals. This is known as a parallel connection (See Figure 48).

Horizontal Passive Bi-Amplification
Horizontal bi-amping allows you to use two different types, models or brands of amplifiers (i.e. tubes on top, transistor on the bottom). However, we recommend that you use two identical amplifiers (i.e. same brand and model). If you must use two different amplifiers, it is essential that they have the same gain or that one of the two have adjustable gain so that you can match their gain characteristics. If the amplifiers of choice do not have the same gain characteristics, then a sonic imbalance will occur.
With horizontal bi-amping, one amplifier drives the high pass (ESL) section while the second amplifier drives the low pass (WOOFER) section. Connect the low frequency amplifier to the lower set of binding posts of both speak- ers. Connect the high frequency amplifier to the upper set of binding posts (see figure 49).
