The door casing is such a huge, 200 meters it vibrates O_O
The bass is not superb at 1 meter from the box but 3 meters, a breathtaking.
The bass is deep, but it tappe nice enough.
The charge is a pavillionaire but the boomer is bass-reflex. Basically, the event opens into the clubhouse.
The woofer used is the EV X180B, which is a very good woofer.
The price is expensive but the quality is there! One of the best subs I've ever listened to!
