Some speakers like my NHT 2.5i's have bi-amp capability. No electronic
(pre-amp level) x-over needed. There are 2 sets of posts at back of each
cabinet. I have (2) stereo 100w/ch amplifiers separately connected, 1 for
woofer and 1 for mid/tweeter. These are fed from pre-amp which conveniently
has 2 outputs. As for level control, the woofer amplifier has gain control
at back of unit. If you really do not have two pre-outs you may have to go
with a RCA jack Y-connector. EBAY has various ModSquad, Audioquest and
StraightWire Y's for bid right now.

Results: definitely more presence in my large-ish living room. More bass
with 100wpc dedicated to that driver. I suppose a 200wpc amplifier would've
done same but I like the building block method. Easier on my checkbook.

It may sound better to you but your analysis is faulty. As the
mid/tweeter draws so much less power, the amount available for the
woofer is not much increased. And a single 200w amp could provide
more but I cannot say whether it would make any difference.

Again, in the two bi-amp systems I have used, no line level crossover was
needed (below statement ???).

hope this helps

Just another anecdotal report.
