Hi guys up for grab The Boston Acoustics M350 is the flagship 3-way floor-standing loudspeaker from the brand’s M-Series,It is distinguished by its slender tower profile, which utilizes multiple small drivers to achieve deep bass while maintaining an elegant, room-friendly aesthetic.Core Technical SpecificationsThe M350 is designed for high-end home theatre or stereo setups, requiring a robust amplifier to drive its 4-ohm load effectively.Design: 3-way, reflex-loaded floor-stander.Driver Array:Tweeter: 1″ (25mm) Extended Wide Bandwidth (EWB) soft-dome tweeter with a central dimple for reduced distortion and better dispersion.Midrange: 4.5″ (114mm) mass-loaded polypropylene-cone driver housed in its own separate internal chamber to prevent interference from the woofers.Woofers: Four 5.25″ (133mm) polypropylene-cone woofers. This vertical array provides the surface area of a single 9-10″ woofer but allows for a narrower cabinet.Frequency Response: (40Hz–30kHz} (-3dB}Sensitivity: (89text{dB}/2.83text{V}/m).Impedance: 4 ohms nominal ((3.2text{ ohms}) minimum).Recommended Power: 50–500 Watts.Key Innovations & BuildLo-Q™ Cabinet Construction: The cabinet is made of a “sandwich” of two MDF layers joined by a thick layer of damping adhesive to minimize vibration and eliminate resonance.Aesthetics: Finished in high-gloss black with a black leatherette-covered baffle and solid aluminium stand-offs.Crossover: Features a complex filter circuit board designed to blend the six drivers seamlessly at transition points of (400text{Hz}) and (3text{kHz}).Performance CharacteristicsSound Profile: Known for a “lush and exhilarating” force in home theatre setups and a detailed, spacious soundstage.Bass Performance: The four-woofer array helps minimize floor reflections and offers tight, accurate bass, though some reviewers noted the low-midrange can be “generous” if the rear ports are left unblocked in smaller rooms.Pricing (Historical): Originally retailed for approximately $2,498 per pair ($1,249 each(Ken Ishiwata recently hosted a very special music event in Music Matters, Birmingham. During this event Ken gave an exclusive demonstration of the Boston Acoustics m series loudspeaker range.) Ken Ishiwata design the M-range for Boston acustics
