Pacco arrivato in tempi giusti, packaging perfetto, subwoofer ottimo, rapporto qualità prezzo, scende molto in frequenza, ma allo stesso tempo il suono della cassa è martellante, ottimo prodotto. Utilizzato in un sistema PA autocostruito così composto 2 sub e satelliti da 6 full range da 2,5". I vicini mi cacceranno
