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
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.

"We were thoroughly impressed with the system, which created a gorgeous collage of sound, wrapped in a beautiful and well-engineered package."
Mark Fleischmann , Home Theater
"That’s why the Boston Acoustics M Series is a speaker system for the times we live in now. It will do anything—and I mean anything—to get your attention. It wants to be the tail that wags the dog, the component that makes you need the other components that make up a system, the tipping point of temptation, square one on the path to a real system. It wants you to take one look and say, 'I want that."

"The M Series has been the beneficiary of BA’s long legacy and bears testimony to the fact that good things can come in small packages. After living with these little fellows for nearly two months, and enduring the tedious but essential break-in process, I was rewarded with surprisingly big sound belying their modest size."
