active crossover freqncy for Totem Mani2

More to add - my thought process is that I am concerned that the class A sound in my setup is not going to lass very long... or not?

Ok, are you ready, You can make this work... Get yourself another amp. Use your y connectors...or another preamp. Run one amp full range to the woofer. Use your electronic crossover and run it lower than the crossover point in your mani 2's. Say 2.5k. Run your second amp through the crossover and back into the tweeter tap of your mani's. You now have the benefits of biamping without destroying the integrity of your Totems.
The Totem crossovers are in tact and working as designed. One amp runs the woofers full range, the second runs the tweeters, electronicly crossed through your Accuphase.
This will work with good results.

Agreed, it will work, but will it compromise sound quality?
I guess there's only one way to know...:)

Metronet, you should ask a dealer or company about the load and your 80%. As long as it doesn't sound overloaded, I would think it fine. Manis are a notorious load, down to 3 or 3.5.

Very interesting idea. What's the benefit of doing it this ways as opposed to the regular passive horizontal biamping? Also, there's no crossover in the tweeter section? Thanks.

The Electronic is crossed slightly below the tweeter, so the Mani's own passive will still work as designed.
As far as benefits, it is for the tweeter only. The bass requires a huge percentage of the amplifiers power, so that amp will do its job as normal. The tweeter's amp will have the benefit of playing no bass, it will have all the normal benefits of Bi amping.
