Used product for about 2 years.

Problems arose at the subwoofer, slamming the extinction or ignition, or does any more bluntly. I did the repair in a specialty store, it works very well since.

The box is given to 20hz-3db, he really falls down to a diameter of this size.

They do not saturate at high volume too, but are aggressive again.

The remote is a more significant
