The compact MR-118B sub-bass system has been designed to be used with MR-112 and MR-115 full-range systems to extend and increase the total low frequency output power. The MR-118B provides good mid-bass punch with extended sub-bass output from a direct radiating 18"(460mm) driver with a 4" (100mm) high temperature voice coil.

The system features substantial birch ply construction and large area porting to reduce air noise. It can operate in passive add-on mode using its internal switchable passive network or may be used actively using a suitable controller. The MR-118B has a top hat that can be used as a pole socket to mount an MR-112 or MR-115 above the sub-bass enclosure.
