Recommend me some good subs around $600.

My 15" subs cost $250 each to build, and are better than $800 subs I've bought. Not as good as the Titanic for Home Theater, but definitely a step up on them for music, that was a trade-off I wanted. Personally, when you get down to 23 Hz or lower at 100 dB for movie effects, it's all the same to me, I haven't thought twice about it.

I don't suppose you would share your design

Not my design at all, but it's the extremely popular value-leading Dayton Quatro 15" woofer and a 240 watt plate amp...make your cabinet anywhere from 2.5 to 3.5 cubic ft internal volume - (I went 3.5 for a low Q of 0.67). 3/4" MDF is fine, I like double thicking the front baffle. I used a shelf brace at the midpoint and some shims at corners.

There's been a zillion of these made, and every audio website I visit has a few people with this design. I have no idea who thought to combo them up first. For all but the largest rooms they'll rock the house, but the low xmax design and good efficiency make this a stellar woofer for music. There's better designs out there, but not for the money, yet. Throw in a Behringer Feedback Destroyer for Parametric EQ and you have a total bass solution for any room at less than $350. My old HSU VTF-2 and Paradigm PW-2200 were great for movies, and definitely added some punch to some forms of music, but they had that typical boomy sub "hangover" effect that a lot of ported designs have. For half the price I got more bottome extension, better sound definition, more output and full parametric equalization.

This works great for people who want their home theater to tackle music as well. Of course, you can spend a bit more and do better, but this was the best cost/performance benefit I could find at the time. My critical music listening is done on my 2-channel rig.
