Jared Alonge:
hey guys, me and my friends do huge teen dances and our next one is in cleveland. were looking at getting 2000+ kids in a room thats 160x250 feet and has a little over 30' ceilings. we want to get enough bass that you can noticeably hear it bumping from out in the parking lot. In our research we have come up with Mccauley M88s to be the best route to go, however were not sure what to do amp wise, i guess what im asking is what are some subwoofers that will give us what we are looking for bass wise and then ill go from there about amps. we already have 4 jbl 625s, a cerwinvega cva 21 powered sub and 2 15" jbl eon subs. mids and highs wise, we think we are fine with sound, but we want to have A LOT more bass so going from what we already have, we want a lot more. thank you for any information and experience you have

Rent a system and that way you don't have to waste your energy on sound equipment. This will leave you plenty of time to do your promotion and do the actual performance.

For a high energy dance event for 2000+, go and hire a professional outfit.

If you really want to do it yourselves, at least 4 x M88s per side and some decent top boxes. Make sure you splay the tops to avoid comb filtering. For amps look at Lab Gruppen fp6400 or better or Powersoft K10s.

I really think you would do better to hire somebody local with the kind of system needed to do this - this is not a small room, which means it is not a small gig.

Hire 16x EM Quake subs with Powersoft K10 amps + Stand back and enjoy ;)

Duncan McLennan:
I'm going to second the comments about hiring in a system that's adequate for the gigs.

It's obvious that you don't really know much about large scale system design from your list of several different types of subwoofers. Are you trying to use them all at the same time?  It's possible you'll actually get LESS sound from using a number of different types of subwoofers thrown together at random.

How did you come to the conclusion that the McCauley M88 is the best sub for the job? There are plenty of ogod 2x18 subs out there.

No matter what loudspeaker you end up going with, I suggest you standardize on one model across your whole inventory. You can always take a single 2x18 to small gigs. Then take more to larger shows.

As for amplifiers, look for an amp with about 1.5X the RMS rating of the loudspeaker (at the speaker's impedance).
