Used it for 15 days
Amplified system with active filtered.
HP 18 "(46 cm)
500 W RMS 30-150Hz
Active filter built-80, 120 or 150 Hz choice.
Dimension: 60 * 80 * 60 cm
130dB max SPL
54 kg, it is not pretending ...

I use a single caisson 6118 complment speaker "acute medium" with 38 and 1 "driver
big advantage to have the amp integr .Construction plywood 20 mm very heals.
HP's 46cm is really impressive efficiency: fishing and deep bass.
This box is a + SUB subwoofer bass.enfin ... both !!

Really happy over all sub I could listen, but often powerful precision
and his drooling ..... cry! (Except for Turbosound !!! and APG, but I do not have the chance to play in the big leagues!)

THANK ANTREPRO (or I bought the hardware) for their availability and comptences.
