Bought one......then bought another. I cannot say enough about this sub. I am using two of these along with the BX 5s. This system can go louder than your ears can handle. I produce heavy bass music and these deliver. I have them crossed at 120. I can also put on Saving Private Ryan and be on the beach. No joke.

Features? Electronic crossover networks in both subs. I found that one overrides the other so one has to be the master and the other the slave. Pure bliss.

Hook em up, get small satellite monitors like the bx5 and you are set.

Heavy duty.

The best.

Not needed it.

Well they reside in the corners of my studio.....lurking to say the least.

bass

I have a small studio and this was a great addition to my DX4's.

It has everything I need like that extra punch I needed from a subwoofer!!

Hooked it up in 5 minutes. Adjusted the levels in another 5 minutes.

Quality is excellent!! I'm hooked on M-Audio speakers!!

Great value!!! If you need a subwoofer, this is the one to get!!

Only reason I'll call is to order more.

R&B, Hip Hop

this really improved my monitoring setup. i have the 5" M-Audio nearfields and while they sound surprisingly good by themselves the cross-over feature in this sub allows them to focus on what they do best. i haven't tested different locations for it but i did tune the cross-over freq & phase. since bringing it home i have been playing all of my instruments and some of my old mixes and it just brings them to life--again, the bass is good but the main improvement comes from the fact that my small speakers don't have to deal with the bottom end any more. i can play synth patches and 5-string bass at levels that i feared would tear the BX5's apart before, now they are clear and powerfull.

the adjustable crossover is the only feature that you need.
