The Stage Plus padded protective bag for the Plus Audio MPS15A is a fitted soft cover made for the Plus Audio MPS15A 15-inch active loudspeaker. Stage Plus is AV Distribution's in-house cases and staging brand, and this bag is the same cover supplied with the 'MPS15A including Stage Plus Bag' bundle. It slips over the speaker to protect the cabinet finish, grille and rear control panel from scratches, dust and knocks during transport, loading and storage, which matters for mobile DJs, bands, churches and rental companies that move their PA from venue to venue. The black bag carries the Stage Plus logo and is shaped to the MPS15A's trapezoidal cabinet. For reference, the MPS15A itself is a 1000 W RMS / 2000 W peak, two-way active speaker with a 15-inch woofer, 1.35-inch compression driver, Bluetooth with TWS, a 2.4-inch colour DSP display, a 35 mm pole socket and M10 rigging points. Only the bag is supplied: the loudspeaker is not included. Check that your speaker is the MPS15A before ordering, as other models may not fit.
