How does that sub sound without being in a sealed box??

Hi, Thanks for your kind comments,

My job is seller and intaller of hi-end sound equipment like Krell, Mcintosh, Jeff Roland, Sonus Faber, JMLab, etc...

The enclosure of the sub is not totaly sealed (like a hibrid sealed/bass reflex box) and works very good, i have some foam in there for cansel some reflections and have a good Audison amp only for the sub. So the quality sound i get from this sub is ok for a car, its controled and deep i have mine cut in the head unit at 60Hz and sometimes at 80Hz for some musics.

Regards,
