Mojo ... the tweeters don't need the power, but as it's currently not possible to get an amp with a 1500 for the woofers and a 1000 for everything else, we match amps.

I did mention to Ian that a tailor made amp with a single 1500, two 1250 and two 1000 channels in a single box, with two boxes required for a speaker pair, would make a great solution.

I think that would require different voltages on the rails for each amp's finial stage ... maybe you might be able to share one mother of a transformer but think little else. Plus the fact that you're limited to what a single outlet can provide.

Instead if you actually thought you needed more than 1 1500 per A-LFR speaker then I'd suspect the best bang for the buck would be something like, and I say this from intuition and without real knowlege of what each of the 5 sections draws under real music conditions, 3 ADA 1500 or 2 ADA 1500 + a 1250 ... a dedicated 1500-1 for each speaker's woofer and 1 ADA-8 for everything else ... I'm sure Ian or Andrew can tell me why the mids and tweet need more to balance out the dedicated 1500-1 ... I mean someone at Axiom (Ian seems likely) felt that insane power of all those amps could at times be needed (at the same time).

Rethinking the balance maybe a dedicated 1500-2 for the woofers and front mids per speaker and a 1250-6 for everything else.

The one box concept would not necessarily mean one electric cord. Earthquake has done dual cords for years.

The guys are toying with some ideas. There are so many options now. Your idea of 1500's and 1250's is also solid, with the possible change to a 1500-2 for the woofers and a 1250-8 for the mids and tweeters.

The whole idea is it doesn't cost a fortune to get active sound.

I am glad to hear Axiom is thinking about it; there's a lot to think about.

I hope so. Looks like I have 1 20A circuit for the living room and 3 20A circuits for the vault / gun room.

That is not how I would have allocated the circuits... total power to the gun room is maybe 30W for lighting and 40W for dehumidifier.

On the other hand Ian's amplifier stack probably needs its own transformer out by the street.

3x20A circuits in the gun room is barely enough for your plasma rifle.

Craig, is this your last speaker purchase?

I thought I was ahead of the curve by putting a dedicated 20A circuit in the theater in addition to the shared 15A. Should have added another...

Oh no! I'm happy with what I have! I don't have that kind of budget now and my room is really not ideal for omnidirectional speakers. With 11 speakers in a 16x18 ft room, I can get nice surround by putting the system in... surround.

But I will say that with the new M100s for the little I got to play them, the wife and I both enjoy listening to music in pure stereo now. More playing this weekend when I get home.
