Product Overview

The E15X-SUB is a compact, light weight, high performance subwoofer for use with d&b E-Series loudspeakers.

The built in passive crossover network allows the E15X-SUB to be operated in parallel to E12 or E12-D loudspeakers on the same amplifier channel, greatly extending the low frequency headroom and bandwidth of the systems. Alternatively it can be operated actively driven by its own amplifier channel without the need for any changes to the subwoofer. In active mode the E15X-SUB can be used to supplement any of the E-Series cabinets.

The E15X-SUB can be driven either by the d&b D6 or D12 dual channel power amplifiers configured for the E15X-SUB. It may also be driven passively with E12 or E12-D loudspeakers from the same channel of a D6 or D12 dual channel power amplifier using the E12-X or E12-DX configurations. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.



The E15X-SUB cabinet is constructed from marine plywood and has an impact resistant finish, a pair of handles and an M20 threaded flange on the top to accept the d&b loudspeaker stand winder. The loudspeaker cabinet is also available in Special Colour (SC) and Weather Resistant (WR) options.
