Description

The BPSD21-S3 Sub Engine comes with the most powerful low frequency transducer we have ever found. It boasts folded-horn output from a box one -half the size of one of our WH folded horns. The 21” Neodymium woofer has a 6” voice coil that can handle 2500W RMS, 5000W Program and 10,000W Peak.  When it is used with a bridged 6000W amplifier, the low frequency output is staggering. The frequency response curve is 3db down at 32 Hz.

The tour version is available with handles and an attachable wheel-board.
