Boston M 350

Features of Boston M 350

M350 3-way floorstanding: 1-in EWB dome tweeter, 4.5-in midrange, 4 x 5.25-in woofer. (Price shown for each.Experience rich, full-range sound while enjoying music, movies, and more using the M350 Floorstanding Loudspeaker from Boston Acoustics. This three-way speaker combines a 1-inch Extended Wide Bandwidth dome tweeter with a 4.5-inch midrange and four 5.25-inch woofers for smooth, natural sound and dynamic bass. The M350's Lo-Q cabinet is built to reduce vibrations and eliminate unwanted resonances. The M350 can be used with 50- to 500-watt amplifiers and has the highest power-handling capability of any Boston M-Series loudspeaker.

M350 Floorstanding Loudspeaker is equipped with Boston's signature 1-inch Extended Wide Bandwidth (EWB) dome tweeter, which is designed to cover a broad range of frequencies, reduce distortion, and improve clarity in the high registers. Unlike most tweeters, the EWB has a small dimple in the middle and a large radiating surface that extends from the center to the outside perimeter of the diaphragm. This design enables the tweeter to track subtle treble details and reproduce the highest frequencies with ease.

A 4.5-inch polypropylene midrange employs mass loading to dampen harmful resonances and achieve a smoother frequency response at the top of the driver's range. The M350 also features an array of four 4.5-inch polypropylene woofers that produce multiple floor reflections that minimize sensitivity to placement and optimize bass response. The woofers feature aluminum shorting rings for dramatically lower distortion and a clearer sound.

M350 has a cabinet made of Lo-Q, a material consisting of two pieces of medium-density fiberboard joined together with a thick layer of damping adhesive in the middle. This material significantly reduces cabinet vibrations to virtually eliminate unwanted resonances allowing the M350 to create a larger, more vivid soundstage.
