Product Overview

The 27S-SUB is a compact high performance cardioid subwoofer powered by a single amplifier channel and is for use with the xS-Series and xA-Series loudspeakers.

The cabinet houses two long excursion neodymium drivers in an integrated cardioid setup: a 15“ driver in a bass-reflex design facing to the front and a 12” driver in a two chamber bandpass design radiating to the rear. It can be used stand-alone, stacked or individually flown.  The loudspeaker cabinets and most accessories are also available with the Special Colour (SC) option that can be executed in all RAL colours, whilst the Weather Resistant (WR) option provides an IP34 rating, and enables operation of loudspeakers in changing ambient conditions.

The 27S-SUB is driven by either the d&b D6 or D12 dual channel power amplifiers configured for the 27S-SUB. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.
