The 21SW4000-NDY-4 21'' neodymium subwoofer from PRV Audio is the perfect solution for extreme systems where a measly 18'' driver just will not do. With nearly 60% more surface area than most 18'' drivers and an incredible 18 mm xmax, this driver can move serious amounts of air. The 21SW4000-NDY-4 is an ideal choice for use in clubs, live venues, and high output car audio systems.Capable of over 6 liters of displacement with each stroke for incredible output
The 21SW4000-NDY-4 features everything you have come to expect from PRV's high power drivers. The massive neodymium motor has extensive venting (vented pole piece, 10 radial vents in the back plate, and venting between the motor and frame) to create forced convection cooling for the voice coil reducing power compression and retaining sensitivity at high output. The 6'' high temperature voice coil uses an inside/outside winding configuration, further increasing power handling. Dual spiders and a heavy-duty cloth surround support the pulp paper cone, which has edge reinforcement to ensure no deformation around the high stress cone-to-surround joint. An incredibly rigid cast aluminum frame holds all of this together.
Massive 6" inside/outside wound voice coil handles easily 2000 watts
Extensive motor and coil venting keeps power compression to a minimum
