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.

Product Research


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.

Boston Acoustics M250

Written By Dawn C, Everett WA on Monday, December 29, 2014

Crutchfield Customer Review (What's this?)

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.

Pros: Great sound, small footprint, nice look.

Cons: None so far.

Crutchfield Customer Review (What's this?)

These were replacing some lower end bookshelf speakers and I was amazed by the improvement. The towers look great and sound great. After a few weeks of use they continuously handle high volume very well without any kind of feedback. The only issue I have is the base of it is not completely flat so it is not as sable as it could be. Still overall definitely worth the purchase.

Pros: Look and sound great

Cons: Tower is not completely stable, wobbles back and forth some.

Written By JAHenke7, Wenatchee,WA on Friday, November 28, 2014

Crutchfield Customer Review (What's this?)

I have always been a Boston Acoustics fan and the M250 is just another reason why I love Boston Acoustic speakers. Amazing sound and amazing bass in such a small tower speaker. I would highly recommend these to anyone. From the low end to the high end these speakers rock. And they will handle very high volumes without clipping or distorting.

Pros: Beautiful cabinet and amazing sound quality.

Cons: I wish the speaker stood a little taller. They just look so small in my living room.

I Wish I Didn't Live in an Apartment

Written By Amature Audiophile, Seattle, Washington on Monday, October 06, 2014

Crutchfield Customer Review (What's this?)

I'm sure I could write more if I had a chance to push these speakers but I live in an apartment complex and try to be respectful; however, I've done what I can to enjoy these speakers and they've sounded great! The comfortable size, stylish look, sound quality, and price have made me very happy with my purchase. Thank you Crutchfield!

Pros: Great look, good size, and very stylish. Easy to hook up. Sound quality stays good at higher than normal volumes remaining clear and clean. My system includes an older and lower end brand name receiver with outputs for dual subs of the same manufacturer and price range; I can't wait to see what these speakers sound like with a new receiver and better low end support. The speakers also come with different base attachments for carpeted/hard floors.

Cons: Boxes arrived looking pretty abused by the shipping company but the speakers were well packaged and no obvious damage was identified. And I'm not exactly sure why this two year old product was already on sale for the discounted price, but at this point I guess it doesn't matter. I'm thrilled with the product and the quality... and the discounted price makes it that much better.

Questionable quality control, scooped mids

Written By Thomas P, Seattle, WA on Saturday, August 23, 2014

Crutchfield Customer Review (What's this?)

I've been a Boston Acoustics user for 3 generations of product lines (over 12 years), so I was excited to see these on Crutchfield at such a great price. First impression was good; clean lines, good build quality to the cabinets. Unfortunately, the good points stopped there.

1. One of the speakers arrived with a blown woofer. I'm shocked that BA would ship a cabinet from their top-of-the-line series with a blown driver. While I don't expect a full frequency response chart at this price(although it might be reasonable to expect one at $750), I would expect that they'd run a basic sound check as part of QA / QC. Nope.

2. Despite sporting a full tweeter / mid / woofer combo, these speakers are surprisingly unbalanced in the midrange. The mids are not just "flat", they're "scooped". I paired the non-blown speaker with a Boston Compact Reference series speaker; the difference in the soundstage was amazing. The soundstage on the side with the M250 sounded like it had a hole in it. The midrange was very weak.

This might be the kind of thing that would improve as the speakers break in, but I'll be sending these back.

Pros: - Tweeter is very clear and has good tonality - Crutchfield's customer support is great; these speakers are going back tomorrow

Cons: - Mids are very weak and totally overpowered by the tweeter - One speaker arrived with a blown woofer; no quality control even for the top-end speaker line? I think this will be the last Boston Acoustics product I'll ever buy

Boston Acoustics M250 speakers

Written By RoCo, Delaware on Monday, July 14, 2014

Crutchfield Customer Review (What's this?)

A really clean sound, at once I was aware these guys were infinitely better than the old (apparently junk!) speakers I was using. These speakers have performed as you would expect for this level of speaker from Boston Acoustics. I can't say I bought them for their looks, but they _do_ have a nice look to them too. I couldn't be more pleased with the purchase, and Crutchfield was excellent throughout, so I couldn't be happier with the purchase process either!

Pros: Excellent sound, good looks, not massive but still provide "presence".

Cons: Nothing to complain about (if you're into that type of thing!). :-)

Supreme Sound

Written By Anonymous, Clifton Park, NY on Sunday, March 30, 2014

Crutchfield Customer Review (What's this?)

The speakers are even more classy looking than I could have imagined. For tower speakers they are very space conscious. Now for the sound, I could say WOW and it would say a lot but these go above that. They fill my room and are very crisp and clear allowing you to hear every little detail. With the right TV you will not want to go out to the movies. I'm even more excited I took advantage of the buy one get one. Thanks crutchfield!

Pros: Big sounding towers but not space consuming. Elegant. Even better when you have these as your rear speakers too. Well worth the money.

Cons: Can't find one if I tried!!
