I love this sub! I have a system In all 3 floors of my house.
I use this Jbl in my bedroom paired with nht 2.4. I buy and sell audio so I always get some nice stuff to play with before I sell. I've sat this Jbl aside while I've had velodyne all series specially the digital drive series which is nice, Polks psw505, Boston, nht, as some. And the Jbl is by far the best. The bass is very deep and no with no port chuffle. The speaker cone does heat up quite hot as I think the amp is more than this light polyplas woofer can handle. The cone is very light yet lighting quick. I love this sub it's great wireless had a teeny lag. But all in all I give it a 910 a stiffer cone with more weight would had had more heavier bump. But it's all cons and pros. And also I bought this open box and it had no grill. Jbl sent me a free grill. Normally would have been 90$ with shipping. Great job Jbl!
