Overview

Upgrade your home theater system and enjoy exceptional surround sound with the MCenter Center Channel Loudspeaker from Boston Acoustics. Along with a pair of 4.5-inch polypropylene cone woofers, the MCenter features a 2.5-inch Balanced Mode Radiator (BMR) driver for consistent sound across a wide audio range. The speaker is short enough to fit easily on shelves and walls, and its ports have been put on the front to limit proximity effect when placed in cabinets or near walls.

Lo-Q Construction to Limit Vibrations
The MCenter 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 MCenter to create a larger, more vivid soundstage.

Balanced Mode Radiator Driver for Optimal Surround Sound
The MCenter Center Channel Loudspeaker features Balanced Mode Radiator (BMR) driver technology, designed to improve dialog and surround effects across a broad listening range. The 2.5-inch BMR driver uses a flat panel diaphragm that operates in two modes simultaneously. To reproduce lower frequencies, the diaphragm moves in and out like a piston--similar to how a traditional driver works. To reproduce higher frequencies, the diaphragm bends.


These two modes of operation significantly extend the usable range of the driver, resulting in enhanced high frequency dispersion for more consistent surround sound. A low crossover point delivers clear sound reproduction in midrange frequencies where the human ear is most sensitive. The speaker also contains two 4.5-inch polypropylene cone woofers for dynamic bass.



Short Cabinet for Easy Placement
Because it uses a BMR driver, the MCenter is shorter than typical speakers with a stacked tweeter and midrange. As a result, it can more easily fit on a shelf under a display or hang on a wall.

Reviews

Ryan Wanaita, Digital Trends
"We were thoroughly impressed with the system, which created a gorgeous collage of sound, wrapped in a beautiful and well-engineered package."



Lawrence Devoe , Blu-rayDefinition.com
"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."
