Subwoofer choices
 

Trying to get some feedback on some subwoofer choices. I'm looking at a single 12" driver in a sealed box. These are my choices which are all single 4-ohm and about 350-360 watts rms. My amp is a 360a2 which delivers 360 watts rms into 4-ohm mono

(1) Soundstream Picasso PW-12
(2) Polk Audio db124
(3) Infinity Perfect 12.1

Price is about the same for all 3 brand new

Out of the three, personally I would choose the Infinity. With that said, however, I have not heard the Picasso.

Depends on your budget, out of the three I would say the Polk is the best bang for the buck.

One more for Infinity Perfect

Infinity here. Been pounding mine for 5 years and their still going strong, and I'm getting impressive numbers out of them for spl this season also.

What is the goal? Ultimate SQ, ultimate SPL, or a healthy mix of both?

The 360a2 is good for 400+rmsx1@4ohm and there are plenty of great choices in this power range.

Going for SQ mostly. I want to be able to hit every bass note (highs and lows) with precision and clarity. Doesn't have to be a loud subwoofer. I'm looking for clean bass.

And yet another vote for Infinty Perfect, if all you need another push :)
Infinity came out of nowhere with the Perfect Series sub. Way beyond their lower end like regular Kappa. Very good SQ.

the infinity is a magnificent subwoofer regardless of price...very clean and well behaved and it gets plenty loud. I have not heard the other 2, so i can't honestly comment on them.

A few to consider in no order:

Infinity Perfect
Pioneer 12PRS
Image Dynamics IDQ
Boston Acoustics G5
