No it's definitely right. The only errors are of omission. I spoke with Wendell over the phone today and he assured me they cannot be bi-amped. I understand that is not strictly true, I could physically undo everything and amp it how I please, but I understand his message.
Unfortunately he didn't seem to understand biamping is less about the speaker and more about the amplifier...
Not sure what I'm going to do. I'm sure the dealer won't want them back in the condition I have one in. I think I will install them in my frames sans bi-amping for the time being, and try and work through the schematic. At some fundamental level, there is a signal present to the tweeter/mid combo and it can be recreated prior to the amp instead of after the amp.
Follow Ups:
Perhaps in this case the solution for the amp doing mids and highs is to have it do midbass as well and lighten its load with a pair of powered subwoofers at 80-100hz or so. That way you get the well integrated drivers on one moderately stretched amp while taking out the heavy lifting required for low bass.
Your translation of the Magnestand schematic into ALLXO might be correct, but that doesn't mean it will work. :)
Clearly the midrange would not be producing any sound in your ALLXO example. (That should be obvious.)
Wendell obviously doesn't want to advertise the possibility these speakers could be bi/tri-amped, but of course they can. Any speaker with individual drivers can be successfully biamped.
Dave.
