The improved M1370 BT is more versatile and functional, but with the same affordable value. Equipped with Bluetooth, this 2.1 speaker system can be paired with Bluetooth-enabled devices to satisfy all your audio needs, without the constraints of pesky cables or wires. The subwoofer is enclosed in medium-density fiberboard to reduce audio resonance. It's also equipped with a front-facing bass reflex port for enhanced bass. And a bass trimmer dial on the side of the subwoofer lets you personalize the bass output to suit your taste. Mounted on a stylish, translucent stand, the satellites are designed both for the eyes and for the ears. The upward-angled satellites project sound directly towards you. The unique design also provides stability to the system, effectively reducing possible audio interference that originates from the surfaces.
