Boston Acoustics M350 Tower Speakers

Experience rich, full-range sound while enjoying music, movies, and more using the Boston Acoustics M350 Floorstanding Loudspeaker. 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.

  • 1-inch EWB dome tweeter for greater clarity and less distortion
  • 4 ½-inch midrange uses mass loading for smooth frequency response
  • Four 5 ¼-inch woofers for optimal bass
  • Lo-Q cabinet reduces vibrations and eliminates unwanted resonances
  • Internal chamber for midrange to prevent acoustic interference
  • Five-year limited warranty

The M350 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.

The 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.

The cabinet also contains heavy-duty absorptive fill and internal braces that have been carefully positioned to maximize the speaker's strength and optimize sound. The M350's black gloss finish and curved side panels with faux leather wrap can complement any decor.
