I'm starting off with a 1500-3 and a 1000-8. All Watts in the following discussion are peak Watts.

The 1500-3 will give me 4500W to share between the LFR and 160v2. The 1000-8 will give me 3000W to share with the remaining LFR channels. I also plan to test a 1000-3 in place of the 1500-3.

I think all this will be over-kill; even with the 1000 in place of the 1500. Here's why:

- 0 dB on my Onk is really LOUD in my room through my M100v4 and (any) ADA.
- if I play a 60Hz tone, 0dB on my Onk is 441W across the woofer array. I know this because that triple woofer array is 4 Ohms and 0dB on my Onk is 42V out of an ADA. 42 squared divided by 4 is 441W.
- let's assume the bass signal in my music is really 441W. That makes the mid 36% of that or 159W and the highs 6% of the lows or about 26W.
- for stereo listening, with the 1500 for the lows, I have over 2000W of head-room per channel. Even with an ADA-1000-2, I'd have over 1000W of headroom per channel.
- with the 1000-8, I have over 150W of headroom per channel for mids and 350W per channel for highs...LOL!

So I think for those who are just sitting on the sidelines and aren't sure about what to get for amplification, go with a 1000-2 for the lows and a 1000-8 for everything else.

Keep in mind you'll likely be running an active LFR system with a sub. So that's load that's lifted from the amps.
