Bi-amping Snell Speakers Anyone?

Yes I had them vertical for months and did not notice any unbalance in the volume.

Doesn't sound right to me. If anything, I might have expected the bottom to be more prevalent. Switch the amps around to see if the same thing happens with the other amp on the top.

I suggest you use an active crossover, as you will need to bypass all the passive parts of your speakers.

An overview of the concept is available here:

Thanks for the suggestion Bob reynolds. I have moved the wiring so that one channel of each amp runs the top end while the other channel runs the bottom. Sounds good but I still have the mid/hi channels turned down about 2 clicks.I will do some more testing and will read up on the active crowwover info.
