OMG this thing hit harder than 2 - 13" subs!!! No, not really. I know, because I replaced two JL P1222s with them. The JLs hit harder and had a lot more low end. "Wait, your title says to get this!" you exclaim. Yes, because there is more than just load and low to consider.
I have always loved the way JLs sound, but could never justify the cost. With fatherhood came new sub objectives: size, convenience. and sound. For the cost, this gives me exceptional sound, small size, and the convenience of being in a box already.
The sound quality is awesome. Other reviews state that it sounds like a sealed box, it's true. Not exactly, but so close that I have already forgot the difference. :) I had the JLs in a sealed box, and had 2 other sealed sub-woofer systems in this car. This sounds more musical, surprisingly tight, cleaner, and lower that another single sub I have had. Give it some time to break in, it sounds better now than when i got it. It does low and loud very well to boot.
The size is the what lead me to this speaker, a stroller seems to need quite a bit of trunk space. :) It is sufficiently smaller than my previous box. With banana clips, it's also readily removable. It also removed a lot of weight in the back portion of the vehicle. No, really, the old box was twice the weight. Pffftttt, never again. For the sound and volume you get out of this, it's hard to beat.
If you are downsizing but still want big, clean sound, this is the one.
Pros: Musical,clean, tight, low, loud sound. Smaller size. 5-way binding posts. Solid build. Built in grill. Did I mention I just love the sound? :)
Cons: OMG this thing does not hit harder than 2 - 13" subs!!! (See what I did there?) Seriously, none. This does what it was designed to and does it well.
