I think you can have what you want. As an actual owner of the speakers (different models, but powered bi-polar towers) I can tell you that for a dance party, some time spent setting the levels will most likely yield a great result.

First, remember that bi-polars need breathing room. The farther away from the corners you put them, the better they will sound. In my room, the BP 2002 towers are 3 feet away from the walls behind and to the side. If you don't have that much room, try to get them placed as far as possible from the walls. If you have more, then that's even better.

Second, get yourself an ANALOG meter to measure the sound levels and make sure you match the levels at "C" weighting... I also think it's "fast" but I have to get back to you on that. You have a choice between "fast" and "slow" and if memory serves, the measurements should be taken at "C" and "fast". You will be truly amazed at how loud bass levels are compared to mids and highs.

Also, use a setup disc or digitize that disc to emanate from the SOURCE. Internal preamp or receiver signals are better than nothing, but not as effective as what you will get from your actual source.

We have had parties that sound like a South Beach dance club. There is no reason you shouldn't be able to get the same results with 4 subs.

You haven't mentioned what your front end equipment is. That will make a big impact on the sound. What kind of processing are you doing to the sound?

Also, how are you amplifying them? DefTech speakers love power. the more you give them, the better they sound. Despite being pretty efficient, my BP2002 towers get better the more power I pump into them, particularly the midrange. When I had, for a brief time, enough channels of amplification and I removed the jumpers, feeding 165 watts (passive bi-amping) into each set of binding posts, the clarity at ludicrous volume was amazing and at moderate volumes just seemed cleaner (although that could have been in my head).

I have included a link to the analog sound level meter that I have (mine is the Radio Shack branded one) that Velleman made after Radio Shack stopped making them. It's cheap and when used correctly, will reward you with exponentially better sound quality from your system, especially when trying to level-match two different sizes of speaker.
