Introduction
Thank you for selecting Boston Acoustics. The M Series family of loudspeakers is designed to deliver exceptionally accurate
and natural sound reproduction from an aesthetically pleasing design. Each M Series model is specifically engineered to
provide superior acoustic results for the intended application.
The M350, M340, M250 and M25 utilize the Extended Wide Bandwidth (EWB) tweeter and Boston Lo-Q Cabinet
construction for pure sound reproduction and minimal interference from the cabinet. The MCenter and MSurround utilize
an innovative new Balanced Mode Radiator (BMR) high-frequency driver to provide even sound output over a remarkably
wide area for clear dialog reproduction and an immersive surround-sound field for all listeners. The look of the M Series
includes traditional and modern design cues that provide exceptional sonic results and allow them to easily integrate in a
wide variety of home décors. All of the M Series models are designed to blend seamlessly with each other and to mix and
match with other Boston Acoustics speakers providing great results regardless of the system configuration and speaker
types. We hope that you enjoy your Boston Acoustics purchase for many years to come.
