To confirm:
Main power amp binding posts > speaker level input on powered sub?The source resistance (amp driving main speakers) is extremely low (about 8 Ohm) compared to the very high load impedance (speaker input on the sub, likely around 9k Ohm). The load is about 1000x the source, where ratios of 10-50x are adequate (generally the higher the better). In effect, the load is completely invisible to the source. The amp is a world class body builder lifting a paper clip, if you will.
For the record, an accurate reply requires knowing what is the present AWG and length?
One benefit of a power amp driving a speaker-to-line level attenuator circuit is the IC has less antenna effect vs. a regular line-preamp level output.
Are subs employed as Distributed Array?
