Boston Acoustics MSurround 2-Way Surround Speaker 2.5-Inch BMR Driver, 3.50-Inch Woofer

When we talk about speaker configuration, we are talking about the number and type of drivers that a speaker has. Drivers are generally classified according to the frequency range of sounds they reproduce. Woofers play low frequencies, tweeters play high frequencies and midrange drivers play midrange frequencies between these two extremes. The most common configuration in modern speakers are 2-way and 3-way configurations, which indicate the number of drivers the speaker has. A 2-way speaker has a woofer and tweeter, whereas a 3-way speaker has a woofer, tweeter and midrange driver. In the case of our Signature Series floorstanding speakers, there are two woofers, bringing the total to 4 drivers for a 3-way configuration. A subwoofer typically only has one driver. The reason that speakers have multiple drivers is that drivers perform optimally only within a certain range of frequencies.
