  I agree, as I said in a previous post, I fed my HD215s with 1200w each (from C Audio xr3801s) and that was always ample.

Yep, QSC PLX3402 seemed to be a great amp for these, with up to 3 HD's a side

Most feedback along the way with the HD15 has been that once you get much more than 5-600W per box, you simply don't get any more returns from them. Although the old adage of 2x amp power to RMS is good, from experience, driving them really hard with big amps doesn't actually bring anything more to the table, other than risk of damage (which people have seen when driving hard). This was often with the recommended PD154 driver but also seen with PD156 (off the top of my head) which all considered to be fairly tough drivers.
Go carefully... ;)

Also, do you have wadding/dampening material in your rear chamber? This can help with the sound but I would tend to agree that 120-140 LPF would be about the optimum.
exactly this :P

As Norty mentioned deals Wadding is important in these, if possible I'd try and acquire a dsp to keep the frequency in the recommended frequency band
