Important Note

Watts: The guaranteed long term power rating throughout the usable frequency range of the speaker.

(Translation: the speaker will operate continuously at any frequency within the speakers specified frequency range when driven at this power. The "Watts" rating is similar to RMS, but is really more indicative of long term thermal capability.)

Music Program: The speaker will safely and reliably handle the varying frequencies of musical content at this power rating. The "Music Program" rating is more indicative of what you can expect in the real world with the speaker operating within the appropriate enclosure reproducing music or vocal audio program.

After rebuilding the cabinets...new horns and crossovers, I couple these Eminence 12's with a pair of Peavy PR15's. Its loud. I push 600 x 2 with my crown and run them in a series. For my normal size venues inside, theres no need for an additional sub. The 4 do just fine.
This sub sounds quite nice for the $. Im a mobile dj and I bought some garbage 12" 3 ways a few years ago when I started. It didnt take long before I just quit using them. Recently, I opted to pull out the crap sub and replace them with these. In addition to some new crossovers, the low end is nice and the sound is clear.
It is what it is.
Ease of Use
Plug and go.
Heavy, solid, and rugged. Cant really beat it for the buck if you're looking to rebuild cabinets.
400rms/800 peak for $80ish. Cant go wrong.
