at 89db/86db 8/4ohms you were missing the juice needed to make the speakers sing. Now your speakers are happy. Alot of folks underdrive their loudspeakers. Now you can start appreciating your music all over again...and that's fun!
Follow Ups:
First, bass eats up almost all of the power, very little goes to mid-top end.Second with passively biamping BOTH amps deliver FULL range signal Therefore, amp works as hard in passive biamp configuration as in full range configuration, additional power on tweeter is practically negligible.
Third, even for full range single amp operation doubling the power is only 3db extra, just noticable. If your amp has problem driving speakers, it is usually not due to the power but quality. Good 50WPC amp is better than the average 100WPC, power and drive capability are separate issuees. And he is using that same amp he already had.
(BTW, to double the perceived loudness for the given example above you would need to go from 125 to over 1000WPC.)
Would this config be correct?"I purchased another ST-140 and two y-interconnects and used one amp to power the high end and one to power the low end on each of my bi-wire/bi-amp capable speakers. All bi-wired"
Yes -- this is actually the very diagram that I followed.
The polarity of the low frequency leads for the Left speaker is shown reversed. If it's actually connected this way, you can expect poor bass and poor imaging.
I hope that is just "typo"
Is there a diagram that shows the correct method? I beleive that I tried it as the soundstage diagram depicted and did not like it immediately. I think I'm a bit confused here...
and you will see that second correctly connects + to +, - to - of all amp to speaker connections.
Interesting, Thanks JeffH...
