Boston Acoustics M25 Loudspeaker Review
ImageBoston Acoustics was founded in 1979 and quickly made a name among budget audiophiles, and later home theater enthusiasts. They became a big player in car audio as well. In 2005, D&M Holdings -- the parent company for Marantz, Denon and, up until a few weeks ago, McIntosh -- purchased Boston Acoustics.  For a few years, Boston Acoustics was admittedly off the high-end radar, but in 2012, the company made a big push with a brand new line of products.

The Boston Acoustics engineering team is based out of Peabody, Massachusetts, and they called upon independent German designer, Karl-Heinz Fink, and Ken Ishiwata of Marantz.  Ishiwata is an absolute legend, having designed some of the best sounding components Marantz has ever developed. When I heard he was involved in the development of the new Boston Acoustics line, I was enthralled.  I reviewed several products he has designed, including the utterly superb SA-15S2B Limited Edition SACD player. When the offer came to review one of the new speakers, I jumped.

I received the M25 two way monitors, which retail for $399 each, or to round it off, $800 a pair. Stuffed with proprietary technology and interesting design touches, the M25 features a 1” Extended Wide Bandwidth type dome tweeter coupled with a 5.25” woofer. Boston Acoustics also developed a technology, dubbed Lo-Q, to reduce cabinet vibrations and tame resonances. The M25 is rear ported, with one set of quality binding posts.

The overall build quality is very impressive. These do not look or feel like “budget” speakers in any way. The front baffle is fitted with a leatherette of sorts, and my review samples arrived in a very nice high gloss black finish. M25s are not very big, at around 12.5” tall and roughly 10”deep, but they weigh almost 15 lbs each. They come with a soft fabric grill that Boston says is sonically transparent.  I left them off most of the time, as I liked the look of the speaker with the drivers exposed. The M Series also includes three floorstanders, a center channel, a surround, and a subwooofer.

Set Up & Listening:

I set up the M25s on a pair of 26” Sound Anchors stands where my Harbeth Compact 7ES3s usually sit, with QED Genesis Silver Spiral speaker cable terminated with banana plugs. I used both a pair of Peachtree Audio separates and my McIntosh MA6600 integrated amplifier. Toe-in was roughly 20 degrees, with roughly 3 feet of space around all surfaces.

Determined to run the M25s through their paces with as many different types of music as possible, I started with Swept Away, the new album from bassist Marc Johnson and pianist Elaine Elias on the legendary ECM label. A tonally pure recording, the performances are elegant and the M25 passed this first test with flying colors. The acoustic bass was woody in tone, precise in attack, and the piano notes rang out bell-like, with the percussive effect one hears from a live piano. This was a very good start indeed.
