enough power for a high school dance???

Ya, worse comes to worse I run this but the twelves never seem like enough power for me with all those people, so try to have ur main cabs as high as possible... if you can try to rent a higher rating main speaker or get one.

iv done a smaller dance in the same area it was good except it didnt have the deep bass do you think the 2 single 18's will do the job?

I think you can answer that one on your own.

VM good luck..

Give the subs plenty of power, use a crossover. Set the subs in front of the center stage, on the floor, side-by-side so they are touching each other. This will give you a 3dB boost in your bass output, which is perceived as double the bass. With two 12" 2-ways on each side, you'll be fine.

Technical Note: This is called coupleing, for those who don't know........

serious!?! i never knew puttin putting subs like that would increase the bass by 3db...thats awsome...how does it do that?

The idea of a sub is to move lots of air at low frequencies to create that thump you feel in your chest. The closer subs are together, or in a coupling scenario, the movement of air between speaker cabinets work off each other so in effect it seems to double or even triple the air movement causing an even bigger thump. You notice it even more so when the cabinets are on the floor because low frequencies travel better through solid floors and walls than through the air. Hope that explains it.

ROQ out.

ahhh thanks DJ ROQ

Phasing, my good friend

Does coupling work with band pass subs as well?

Works for me.

Not entirely accurate. Yes, it does increase SPL by 3db, but this is on no way perceived as double the sound. It means it's 3db louder thats all. I will be perceived as slightly louder, but nothing near twice as loud.

For 400 kids that will do. Depends on the location weither it's a commons or gym or wherever. But I wouldn't be nervous about only having that. Should be able to get good coverage with the four tops. Good luck.
