Maybe this is a mic problem, or a Sunfire problem. But, like I said way back when, the raised floor sink is not only the 5 Hz structural/footfall resonance, but it is uneven broadband + & - with respect to hi-fi, and the helluvit is that your house might eat lots of hi-fi LF below 28 Hz. Again, IF this is the case, then this sort of thing can be dealt with by tightening the floors, and/or you can keep turning up the power. If you do have the sub-28 Hz sinkhole, then it is likely to take very strong subs to overcome it, and I would hold off on buying anything until I had solved the equation by rote. Yes, 500W might do it. But I have seen 1kW sub amps clip in large rooms at +/- reasonable music levels, and I am sure every pro will tell you the same. Remember that loading a large volume LF sink with sub-28 Hz is not at all the same as charging a small to mid-size room above 40 Hz. There are certainly better and worse drivers and subs out there; but I would be very surprised if the old lightweight HE drivers can perform acceptably in this situation. Possibly, if they are ganged (and fed all they can take...). Remember, you may be wanting more and more power as you go down from 28 Hz, and this is already well below the point where the light drivers want to quit, and certainly well down the scale from where their "efficiency" is listed.
