Featuring a dual 18" subwoofer pairing in a bass reflex housing, the dB Technologies DVA S30N is designed to pack a muscular, ultra low frequency punch.
This subwoofer can be used as an addition to large PAs and as a compliment to mid and high-range units in stacked arrays.
The speakers's birch multiplex housing is covered in black textured lacquer and equipped with eight grips. On the back is a transport dolly that removes easily via quick release pins to keep the wheels from rattling.
Bass Reflex Horn Housing
This design brings together the benefits of bass reflex and horn systems in a compact housing engineered to render low frequencies with high SPL. The two baffle boards are arrayed in the form of a V. They guide the central bass reflex channel's sound energy into the horn's port.
This funneling action is smooth and uniform, greatly increasing its range.
