Carver amps are simply the best.  I love his audio equipment.  They look heavy, but yours do look nice.  I bet they sound great.  My Apogess, even though they are only 2 3/4" Thick, they weigh a freaking ton!  There are about 200 neodymium magnets per speaker!  They weigh about 150lbs each!

I've never seen or heard them in person, but I've read about them in my quest for ideas.

I have heard Magnaplanar speakers and they are quite remarkable.

I just found it hard to get over the fact that you need 500W/ch. to drive them!

I also don't like the idea that they are SUPER sensitive to room placement.

That's why I put together $30 worth of full range drivers!   

The lines are crossed over at about 120Hz.

The horns are crossed over at somewhere between 600 and 1200Hz. I'm not really sure... I have to tweak it for a couple of weeks before I give up and leave it alone.    

I have not had the horns in the living room powered up for about a year! They've just been sitting there, silent.

BTW I made a crossover on a proto-board with op-amps that is 24dB/oct at 113Hz for the sub woofers in Metal.

That was my first experience with bi-amping. The 12 inch aluminum cones are in a 10 cu. ft. box. They're -3dB at 14Hz!

Yes and you HAVE to use an amp that has discreet transister outputs.  The Apogees have a 3ohm impedence.  Most (if not all) modern IC amps error.  They see it as a dead short.  Horn Tweeters can be amazing.  Beautiful sound.

I guess that's the Easter Egg of this thread...  

I removed 2 Carvers in bridge mode and replaced them with AMP3 !!!

I just set the crossover to about 2.2KHz for the horns.

I think that's the right place.

Nice setup.  I am disappointed to not see any folded horn subs...
