When flown facing rearward, the sub's user removable grille can be moved by the user to the new "front" of the enclosure and the amplifier module can be moved to the new 'rear' of the enclosure, thus obtaining aesthetic consistency when flown with additional forward facing Muse 118FSA's. This simple adjustment means that users creating a cardioid sub package require no additional hardware to achieve sleek visual continuity. The model MUSE 118FSCA comes factory preconfigured as rear-facing for cardioid applications.
The Muse 118FSA features a large area laminar-flow port to ensure no power compression and very low port turbulence. For cardioid configurations with one sub rear-firing and two subs front-firing, more than 15db SPL rejection can be obtained behind the array. Class D amplification delivers 1200 Watts RMS with a frequency response of 33Hz to 100Hz, delivering an SPL of 139dB.
