I have 2 of these amps

Power Output: 220 watts per channel minimum RMS, both channels driven at 8 ohms from 20Hz to 20kHz with no more than .005% total harmonic distortion.
Clipping Power: 247 watts/channel at 1 kHz at 8 ohms - 350 watts/channel, 1 kHz at 4 ohms
Clipping Headroom: 0.5 dB at 8 ohms
Dynamic Power: 346 watts/channel at 1 kHz at 8 ohms - 526 watts/channel, 1 kHz at 4 ohms
Dynamic Headroom: 2 dB at 8 ohms
Total Harmonic Distortion: 20Hz to 20kHz, 0.004 % at rated power into 8 ohms, 0.001 % at rated power into 8 ohms at 1kHz.
Intermodulation Distortion: 60Hz to 7kHz - 4:1, 0.004 % at rated power into 8 ohms.
Damping Factor: More than 1,000 at 100 Hz.
Transient Response: 1.6uS rise time, ~100V/uS slew rate.
Frequency Response: DC to 20kHz, +0, -3dB.
Signal to Noise Ratio: 120 dB (IHF-A Curve)
Speaker Impedance: Accepts 4 to 16 ohms

What do you guys recommend I use to make these amps work to the fullest?
I did a project earlier and had not good results so I am starting over. I want as much spl as possible. Thank you

With an amp that only delivers 550 watts I'd suggest something very efficient.

Something like a folded horn or tapped horn.

http://www.billfitzmaurice.com (Table Tuba or Tuba HT)

http://www.diyaudio.com (goto forums than subwoofers) and start looking through the collaborative tapped horn thread.
