LD-Systems LDV212B Passive Subwoofer
The LDV212B is a high-performance, compact subwoofer designed especially for use with VA4 line array elements. They can be flown or used in a ground stacking variant. The rugged band pass cabinet made of 15 mm birch plywood optimises bass
transmission starting at 38 Hz. Two 12\'\' custom speakers with neodymium magnets and heavy-duty 3\'\' voice coils ensure a maximum sound level pressure of 128 dB.
The LDV212B has a power rating of 700 W RMS and is easy to carry thanks to the ergonomically milled handles. The features include a durable DuraCoat finish, Neutrik NL-4 sockets as inputs and outputs, and an M20 threaded flange for spacer bars.
Thanks to the integral flyware (BGV C1) and an optional rigging frame, the subwoofer is ideal for use with an LDVA4 line array. Of course, the subwoofer can also be used in conjunction with many other LD SYSTEMS full range speakers both for ground
stacking as well as for using with the spacer bar solution.
