Looking to add a second sub or upgrade. The deal is I have 250.00 to spend on this venture and I absolutely can't go any higher. So no one should suggest anything higher. This is my limit. No exceptions.
First option is to add a second ASW-10 from The Speaker Company. This is good clean sub down to about 28hz. But my room is 12' x 21' x 8' so its struggles a bit at higher volume. I would also add the ED parametric eq since I would save roughly 100.00 with this sub.
Second option is to pick up one of the following 12" subs.
Premier Acoustics PA-120 for 229.00 off of ebay. Supposedly has good output to 23hz.
Polk Audio PSW-505 for 249.00 from JR.com. Again according to the review I read it can get down to 25hz with reasonable output.
Boston Acoustics HPS-12HO for 249.00. Looks to have output down to 25hz and should offer the output I need to fill my room.
So in a nut shell would it be better to pick up the the benefits of two subs and the extra output with a little less extension or go with one of the larger subs that I listed.
If there are any other options at my price point Im missing please chime in.
