Experience rich sound while enjoying music, movies, and more with the M340 Floor standing 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 4.5-inch woofers for smooth, natural sound and dynamic bass. The M340's Lo-Q cabinet is built to reduce vibrations and eliminate unwanted resonances, and an internal chamber isolates the midrange from the woofers to prevent acoustic interference.
