In many speakers, as speaker cones vibrate, they also shake the speaker cabinet itself, causing unwanted distortion. Pioneer's ISO Drive Series speakers include an innovative sub-baffle that reduces vibration within the cabinet, thereby increasing sound quality. They're great as a pair (for two-channel music), or as a complete system for theater surround or new digital multi-channel music (like DVD Audio and SACD). Either way, they'll make a sound addition to your home.
