Subs

Go for it. The only thing better than two subs is more than two subs.

Are you familiar with this comany?
Thanks

What's a reasonable price?  How big is your space?  What are you expectations in terms of output?  Just a little fill, or are you wanting to pressurize your room?

It looks like those came out almost 20 years ago.  I wouldn't pay much for them or expect much output from their 8 inch drivers.  If you have a small space and want subs that will add a little heft to the bass and not take up much space, they might be just the ticket.

I've got Maggie's 1.7i  and Klipsch 10 sub and Sony 8  sub in a 13-6 x 17' room with 8-6 ceiling.  I am trying to get a more dynamic sound. It's a dedicated room. They want $550.

Having four subs will give you headroom and will help cancel out room nodes. At that price I dont think you could go wrong.
