I just got my BX5a Deluxes and absolutely love them, but I do notice that the base has a dramatic falloff in the deep range, so I'm now looking for a sub to pair with them. Obviously the M-Audio SBX10 is ideal, but damn is it expensive (3x what I paid for the speakers.) Is there any decently musical sub for sub-$200? I know these get recommended a lot

But I can't imagine they're very good I don't need a subwoofer to rattle a house off it's foundation, but I would like decent accuracy. Is the $350+ range really wear you have to go to get a sub of equal quality to the BX5as?

The daytons are very good for the money and have good extension, but there more rumble than musical you will need to pay a bit more if quality is important to you, This sub would do fine http://www.amazon.com/Prodipe-PRO-10S-Pro10s-Subwoofer/dp/B000UH0UDU/ref=sr_1_1?ie=UTF8&qid=1324656013&sr=8-1 .

I have a similar question as RynoWeiss. My set up is: a Schiit Modi (love that thing!) running into my Behringer Xenyx 802 mixer. I have M Audio BX5 D2 monitors hooked in as my mains. I am looking for a sub that will be comparable in quality to my BX5's. Obviously I am planning on running the sub through the mixer. Any suggestions? 
 
From my initial looking around I have seen these mentioned:
