Looking for a cheap sub...

I would also hold out for a used Hsu. Unlikely to find a used REL for under $500.

I have 2 of these. 1 I bought new the other I picked up used for $400. These can be had easily for < $500. I lived with 1 for 1.5 years, adding the second has really made the difference from a really good HT to an unbelievable HT experience. I'm not sure about using it for music as mine are dedicated to HT. I would say this sub's best quality is it's tight/quick bass, not boomy at all ( sealed cabinet design ).

I don't have experience with REL but did have at 1 time, an energy sub, a psb subsonic 6, the M&K is in a whole other league.

good luck.

Hello,
With your budget of $300, I can recommend a Dahlquist PDQ1200 or PDQ1500, both of which can be purchased on Ebay for approximately $120 for the 1200 and $200 for the 1500.
I own a REL Storm, and purchased the PDQ1200 for $104 shipped(could not pass it up for the price!), and IMO it does a credible job considering the price!

Check out the Rava for $399.
