Experience rich sound while enjoying music, movies, and more with the M25 Bookshelf Loudspeaker from Boston Acoustics. Well suited for small rooms, this speaker features a 1-inch Extended Wide Bandwidth dome tweeter and a 5.25-inch cone woofer for accurate, natural sound and dynamic bass. The M25's Lo-Q cabinet is built to reduce vibrations and eliminate unwanted resonances, and its compact size allows you to place the speaker on a bookshelf, wall shelf, table, or speaker stand.
M25 Bookshelf Loudspeaker At a Glance
Clear, Natural Sound for Music, Movies, and More
The M25 Bookshelf Loudspeaker 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.
The speaker also contains a 5 ¼-inch polypropylene cone woofer driver with aluminum shorting ring for dynamic bass and clear, distortion-free sound.
Lo-Q Construction to Limit Vibrations
The M25 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 M25 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. The M25's black gloss finish and curved side panels with faux leather wrap can complement any decor.

Buying a Boston Acoustics Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with original accessories included. When you consider that a factory-renewed Boston Acoustics product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty (90 days on electronics) valid at any authorized Boston Acoustics repair center (you can look-up locations online here or call 201-762-2100)
Boston Acoustics, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Boston Acoustics certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Boston Acoustics Factory Refurbished" product.
Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
