active crossover freqncy for Totem Mani2

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.

you really, really need to search the archives on biamping. There is one thread on this topic that has some excellent discussion and contribution from Steve McCormack. Find it, read it.

Also, I did biamp my Mani's. The result was at best a marginal improvement. I corresponded with Totem and they indicate you're much better off using a single higher power amp than biamping - so with the Manis the bang for the buck in adding a second amp is ver marginal. Not so with other speakers, but true for Manis. That said, since you have the second amp already - get some Y adapters (they are cheap) and try it. Just do it and you will have your questions answered.

I agree that the improvements will be marginal at best. If you have the hardware already, I'd try it. If you don't I would not. I was only trying to come up with a solution to get it done. I have not seen a really high quality Y adapter either. That would add a very weak link.
Good Luck, Tim

Also, just to be thourough, what stands are you using? Can make a big difference, although you were more concerned about amp clipping, sorry.
Agree with last posts, I think you've gone about as far as you can go with your Accuphase. Love it or move to another amp.
Have fun!

Thanks guys. I am extremely happy with my setup right now and will keep it is and continue to love it. Regarding stands I am using four Target T stands filled with lead shots, two speaker spikes each because the speaker is a bit longer in length. I am looking at the Sound Anchor stands, they look very nice.

Bdgregory, a thread that I could gain knowledge from is exactly what I am looking for. Is this the right one you refereed to?
