affordable subs

i have to say, a w7 has to be the best looking sub...from what i've seen. but, they are obviously not for every system.

i'm curious to see what some of the better 'budget' subs are?

i've had a JL 12w3 before, just switched to Image Dynamics IDQ- the older version 2 (IDQ D2 V2). the version 3 looks like it's alot more subwoofer, more like a JL W6 than W3.

i'm very happy with the IDQ plus it was $30 cheaper than the JL W3.

what other subs under $150 are good deals?
