A "wicked-good speakah" from Boston
The M250 from Boston Acoustics has what it takes to bring your music and movies to life. This slim, graceful tower employs the latest advancements in Boston's speaker technology to give you exceptionally accurate and natural sound. It's equally well suited for use in a stereo pair or as front left and right speakers in a multichannel home theater system. Plus, the M250 looks every bit as good as it sounds. Sporting a glossy black piano lacquer finish with luxurious leather-feel trim, it makes a stunning addition to just about any space.
Advanced drivers for detailed, dynamic sound
Boston's Extended Wide Bandwidth dome tweeter lets the M250 really sing with silky, transparent highs. Unlike most tweeters, this one has a dimple in the middle that stabilizes the linear motion of the tweeter for significantly lower distortion, improved dispersion for a deep, expansive soundstage, and greater clarity over a broad range of frequencies. The M250 also delivers dynamic mids and bass thanks to a 5-1/4" polypropylene midrange and a 5-1/4" woofer with an acoustically tuned port.
Better cabinet construction improves performance
Cabinet vibration, or resonance, is the enemy of clear sound. It distorts and colors the sound of instruments and vocals. Boston's M Series speakers fight vibration with LoQ™ cabinet construction. By using two sheets of MDF (medium density fiberboard) with a special damping adhesive layer between them, Boston created an enclosure that provides the acoustic deadening of much thicker materials without the drawbacks of added weight and increased size. The result is a relatively compact, lightweight speaker that has a very low resonance — or in speaker-speak, a low “Q.”
In addition to the Lo-Q cabinet material, Boston also used a scanning laser vibrometer to critically position the M Series cabinets' internal braces where they provide the most benefit. Then they added heavy-duty absorptive cabinet fill to eliminate internal standing waves. These advanced cabinet building techniques and materials result in speakers with impressive transparency and a large, detailed soundstage.

Features
2.5-Way Speaker Design: This 2.5-way speaker combines a 1" Extended Wide Bandwidth dome tweeter with a 5.25" mid/woofer and a 5.25" woofer for smooth, natural sound, and dynamic bass. Experience rich sound while enjoying music, movies, and more with the M250 floor-standing loudspeaker from Boston Acoustics.
- 1" Extended Wide Bandwidth Dome Tweeter: The M250 floor-standing loudspeaker is equipped with Boston's signature 1" 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.
- Dual 5.25" Cone Woofers: The speaker also contains a 5.25"polypropylene mid/woofer driver and a 5.25" polypropylene cone woofer for extended bass response. Aluminum shorting rings help produce clearer sound.
High Quality Crossover Networks: Very high quality crossover networks featuring low loss film capacitors and low distortion laminated silicon steel core inductors are utilized for greater clarity and minimal coloration.
Lo-Q Cabinet Construction: The M250's Lo-Q cabinet is built to reduce vibrations and eliminate unwanted resonances. The M250 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 M250 to create a larger, more vivid soundstage. The cabinet also contains heavy-duty absorptive fill and internal braces which have been strategically positioned to maximize the speaker's strength and optimize sound.
Gloss Black Finish w/ Leatherette Wrap: The M250's gloss black finish and curved side panels with faux leather wrap can complement almost any decor.
Rear-Firing Port: The Boston Acoustics M250 employs a rear-firing port for higher efficiency and greater bass response. Because of the rear-firing port, the speaker should be placed at least 3" from the wall.
Binding Post Speaker Terminals: The Boston Acoustics M250 floor-standing loudspeaker is fitted with a set of binding post speaker terminals that will accept bare wire (up to 10AWG), banana plugs (single only), spade-connectors, and pin-connectors.
Rubber & Spike Feet: The M250 floor-standing loudspeaker comes with pre-installed rubber feet which are ideal for hardwood floors. Spike feet are also included for placement on a carpeted surface.

We've had these speakers a little over a week and so far, we're very pleased with them. All of our music sounds better. We can hear little nuances that we couldn't with our 25 year old Bostons. The smaller footprint makes them fit into our home theatre system better, as well.
