The Boston Acoustics MCenter 2-Way Center Channel Loudspeaker is a two-way center channel speaker equipped with a 2.5" (6.4 cm) Balance Mode Radiator (BMR) driver and two 4.5" (11.4 cm) bass drivers. This combination creates a heightened, 3D-audio cinematic experience because the BMR radiates not just in a narrow cone shaped format, but across the full 180 degrees. This creates a very open sound stage where each sound effect is perceived to have its own position.
The BMR tweeter responds to frequencies as low as 300Hz (rather than 3000Hz for traditional tweeters) so movie dialogue is delivered from a single source. There is no one sweet spot for the audience. With the single source BMR you are always ensured of crystal-clear dialogue wherever you sit. Lastly, the speaker is short enough to fit easily on shelves and its ports have been put on the front to limit proximity effect when placed in cabinets or near walls.
