I bought this subwoofer speaker on a clearance sale
I installed it in an old house speaker box and i was impressed on how tight the bass is . Its not an explosive blow your trunk lid off the car but a nice tight sound

I've had Jbl before and never had a problem and I don't plan on having one now. Just get a warranty if you get these. You can't go wrong with that. I plan on getting the 6x9 and 6 1/2 to make the set complete.

These speakers work great if you buy the right box and amp for them. Not the most powerful but strong enough to make all the windows shake. Not sure on durability but they sound great for the price.

JBL 12 inch subwoofers sound great. JBL is known to be up there with the best audio systems. I have 2 on a sealed box and they are banging.
