Sorry for the poor quality of the pictures, they're coming from my Blackberry So, I change my sub, and got a 15" Xcon. The first listening sessions, I was sceptical. It was too "new" to play well : had to wait for breakin time. I think that's it now!!! The xcon is way more powerful : I feel the bass is really heavier, my car feels it too. The rain/or light sensor (I don't know what it is) in the windshield fell off. The rear view mirror had already been gone !!! With the same power I am more and more happy. I think the sub plays as well as the Icon : I can listen to all kind of music, not only rap or r&b. When I am listening to a Bob Marley song, I have all the basslines complete : with some other subs I had it was not so good. Maybe I had wrong boxes, but, for example, My Kicker L7 was in a sealed box, not the biggest one recommanded though, but not the smallest. And it was heavy but not accurate enough for me. I was missing some notes, these missing notes were there but not loud enough. The Xcon gives me the heavy part I was missing with Icon. The Icon is a fantastic woofer, for sure, but the Xcon is more for real bassheads, like me !!! You feel like your car is going to fall apart !!! and you love it !!! In résumé : if you want a lot of bass that is good sounding, go for the Icon !
