View Sound Subwoofer Driver, Black, VS-SUB-4IN

The View Sound VS-SUB-4IN is a 4 inch (102 mm) passive bass speaker driver sold as a bare replacement unit for technicians, installation contractors and speaker workshops. Its compact frame suits small ceiling speaker bodies, slim wall boxes, tabletop and column enclosures used in mosques, schools, shops, clinics, offices and small halls. The cone and ferrite magnet motor deliver the low and lower-midrange energy that gives speech weight and keeps background music natural rather than thin. Wiring is by solder tag terminals directly to a low impedance amplifier output, or through a 100 V line matching transformer when the site runs a constant voltage distribution loop. Mount it on a rigid sealed baffle, keep polarity consistent across every speaker in the zone, and install indoors only.
