Thanks Steve. I am hesitant but yes, I am on a budget. Would love to get something for around $150-$175. I just recently purchased a seven year old Mirage sub for my lower level family room (15 x 25 with a tiled floor and carpet over it) and it just isn't enough. It was on craigslist for a hundred and I jumped on it. It was in great shape and for a smaller room this 8 inch sub might have worked.
I am looking to add more so when this 20 year old Def Tech Powerfield came up with a 15 inch woofer

, I thought hmmm

. I have another room, a family room, that has a 17 year old Klipsch KSW 150?, a 10 inch downfiring sub, that works that room well. I am trying to get that sound downstairs. Should I be looking for a front fired unit versus down firing?
So the question is how old can I go on a sub in a 10-12 inch range for less than $200? Anyone else think that I should pass on a 20 year old Def Tech Powerfield 15 inch

?
