The two 13 cm slim cone woofers of these speakers have a phase control design. This design helps to cut back on excess noise. The S-LX70-LR speakers have 2.5 cm titanium tweeters, which ensure a wide range of audio reproduction. The shaped design of these speakers ensure a clear sound with no unwanted resonance. With the S-LX70LR, you can extend your audio up to 2.1 sound (with a S-LX70W subwoofer), 3.1 sound (with a S-LX70C center speaker and a S-LX70W subwoofer), or a 5.1 channel setup (with another set of S-LX70-LR speakers, a S-LX70C center speaker and a S-LX70W subwoofer). The Pioneer S-LX70LR floorstanding speakers come in a glossy black color.
