The BW CM 9 stereo speakers feature four speakers in a single housing: one 1-inch aluminum dome tweeter, one 6-inch woven Kevlar cone mid-range speaker, and two 6.5-inch bass speakers, all of which combine to create a rich listening experience. These BW floor speakers measure in at just 39 x 7.9 x 11.8-inches, so they do not take up much space on the floor. With a weight of 58.5 lbs each, these BW floor speakers plant nicely on the floor to avoid tipping over. With a wattage range from 30-watts to 200-watts, connecting BW CM 9 to nearly any amplifier is possible. A frequency range from 30 Hz to 33 kHz allows these 4-way floor speakers to produce a range of sound that eclipses the average human listening range. These 4-way floor speakers also feature an 89 dB sensitivity, meaning that they can produce good sound, even when connected to a low wattage system. When considering new floor speakers, the BW CM 9 speakers are a good option, considering their wide frequency range and 4-way design.
