Paul -

Thanks for the reply. My speakers are bi-ampable with the dual sets of posts and I had removed the jumpers when bi-amping of course.

The main speakers situation was just a temporary one until I decided how to correct the Amp shorting out situation. I was never able to detect what was causing it before, so basically I just unplugged the one speaker cable from the left main and that seemed to put a bandaid on the situation. I then put the jumpers back on that speaker and had been running the system that way recently.

Last night, I decided to un bi-amp both Mains but not the center. Also, I had to remove the splitters. The volume went up noticably on the Mains then when splitted/bi-amped.

The center in comparison, still being bi-amped, needed to be raised more so than before in volume. These sound level adjustments were done with my Radio Shack SPL analog meter.

I am still not sure if you are correct about the speaker crossover with passive bi-amping. I had understood that was THE big negative about passive bi-amping. I would be interested in more opinions on this.

Anyways, the results in sound I have noticed so far are that the low end seems to be fuller/warmer but the highs arent quite as distinct as they were before. These speakers have very distinct highs where you hear every detail, but it can shred a bad recording.

Thanks again for the advice.

Brian,

I can assure you that the passive (i.e. speaker's) xover is still very much in the picture when passively bi-amping. That's why I had to open up my Tukans and 5120 to snip some xover connections when I went active. That is also the reason why there's not such an improvement when passively bi-amping; the deleterious effects of the passive xover are still in effect. The significant difference when you finally get the passive xover out of the way is a revelation.
