Hi all!
After a listening session to my bridged ginclone, a friend of mine is asking me to build a Clone to drive his Martin Logan Aerius I speakers.
Well, during the session, the amp was sweetly warm (I never felt it so warm, but completely touchable.
He asked me to build a bi-amp bridged clone version, so to separately drive the woofer and the panel.
I don't know how much current it will draw at normal listening volume, I'm not afraid, but I want to know if someone have some suggestions/comments about this idea.
Go!

You'll certainly have to parallel and then bridge. And do it well or your friend won't like it 🙂 The best solution seems to be with a transformer phase-splitter and don't forget to use some really nice power resistors when paralleling
How was the sound?
How was the sound?
Actually, my GC have 24V rails and is not paralleled. We have listened at a quite high volume and it didn't suffer so much (I mean that temp didn't rise very much). sound was the same as in my system with classical speakers.
Trafo is a 400VA.
Splitting high & low freq is made because I think that in this way the chips will suffer less than now, but I don't know how much current each driver will draw. Do you think that this splitting does not address this issue?
Someone have this kind of info?
Thanks again for the responses.
ciao!

Re: Make it small...
I'm looking at the datasheet. Do you know if it sounds as the LM3886?

It doesn't. The tweeter takes practically no power. The sound quality otoh may well be much better.
