Uhmmm...I can only stack 1.8. I need to sink the basement lower into the creek running under my house.

Well if your gonna start modifying the house maybe Ian will come up with one of those “back to the future” subs ... you know the scene.

Ian built that sub. While he was water-skiing. Barefoot. On one leg. And teeth only; no hands.

My future pair of active LFRs will be fed by a 1500 for the woofers and a 1000-8 for everything else. According to the ADA manual and specs on the Axiom site, I'll have 2300 continuous and 7500 dynamic Watts to share between the pair. The break-down for each speaker is as follows. The first number is the continuous rating and the second is peak:

a. woofers: 650/2250
b. front mids: 187.5/375
c. rear mids: 187.5/375
d. front highs: 62.5/375
e. rear highs: 62.5/375

Although the 1000 can share 1000W/3000W amongst the drivers it's feeding, it can only feed about 188/375 to each mid array. I expect therefore my system to ultimately be limited by the power available to the mids.

I don't expect to have any SPL limitation at my 12 foot listening distance particularly given the 800 that will be fed from my Onk and the two 500s being fed off of each DSP. But say I do end up putting a 7500W peak in with no subs. My system will only handle a 1500W mid-range peak (375*4) before some channels of the 1000 go into protection. That's only about 20% mid content (1500/7500) and I've read typical music is 44% mids. Now I don't know where that range starts and stops so the 1500/HP drivers may take some of the load below 250Hz.

Anyway, even if I had more power available for the mids, I'm not sure they can take it. I figure it's the mids that are the weakest compression link in typical music.

Not that I expect to be anywhere close to a practical limit in my application mind you.

My suspicion, and I don't have much data to go by, is that the 5.25" mid-woofer is good to 150W continuous/400W peak from 250Hz to 2.2KHz.

That means each mid array on the active 1100 can take 300W continuous which means a 1500 is needed to get all you can out of the mids.

Thought I’d bring my reply over to this thread with regards to my active 1100 amplification situation...

After a lengthy discussion with Debbie who pulled in Ian, we settled on the best starting point being repurposing my monolith 7 for the front 6 channels and getting an ADA 1000-4 for the rears. I was trying to cut this to the bone and had the idea of just using my monolith to work the front 6 channels and adding the rears later. Ian explained why that would not work with the LFRs and the need for rear amplification.

The monolith and 1000-4 do have a 1db gain difference but because I can split them front vs rear, Ian pointed out that I can use the DSP to balance that out.

Can’t say enough good things about Ian, Debbie and crew for all the help and time taken to get me squared away and I am certainly looking forward to getting my paws on these speakers!

David, thanks for responding. It sounds like you're in good shape. Is this 2.1? If so, what are you doing for subbage?

This is going to be a 2.0 setup for music listening.

No $$$ for subbage :|

Maybe one day I might be able to add an EP600...

I think you will be just fine. I've driven my M100v4 with a 1000-3 to 107dBC clean peaks at 12 feet away in 2.0.
