Amplifier for distributed bass array

Hello all

I have 4 Dayton Audio RSS210HF-4 8" subwoofers I'm looking at putting in a distributed bass array for a 2 channel setup. Room is 13x13x8. Subs are 4ohm single coil and 280 watts rms each. Enclosures are sealed. MiniDSP will be controlling the subs. Amp will be strictly powering the subs. 

I've looked at Dayton Audio's subwoofer amplifiers like the sa-1000 but I won't be needing any of the onboard sub controls due to the miniDSP. Dayton makes a dsp amp but again same thing. How much power would I need to get those subs sounding best? I'm not looking for high spl levels as most of my music is older stuff. But I want to be sure that the subs are moving properly from not being underpowered. I'm open to stereo or multi channel amps but want to keep it to one amp powering all 4 subs. Used or new doesn't matter. $1000 budget. Any beefy amp suggestions for this setup?

Thanks!

Dear @blue_collar_audio_guy  : I don't have experiences with amps to handled those four stand alone woofers.

I said woofers when you posted and mentioned subwoofers that those units in rality are not. In the best condition could go down to 30hz +,- 3db.

 

Anyway, good luck with your amp hunt.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

If it were me I'd go with something very simple, if I 100% wanted to keep the DSP out of the subwoofer:

I use Dayton Audio woofers as well for my DBA and use Class AB amps, namely a Acoustat TNT-200 or Electron Kinetics Eagle 2C. I have also used Bel Canto Class D monoblocks. Really you don't need anything too expensive and just need something that gives you adequate damping.

Nice. I need it to be 2 ohm stable with the way the subs will be wired and that’s another issue altogether. That takes the Dayton out of the picture and many others. Been looking at a recapped Adcom 555. Beefy power supply and 2 ohm stable.
