About the KSP-400
The Klipsch KSP-400 is a three-way powered floorstanding loudspeaker from the Synergy Series Premiere line, featuring an internally powered 15" side-firing subwoofer integrated into each tower for true full-range performance. Each speaker combines the built-in 15" powered woofer with dual 6.5" midrange drivers and a 1" horn-loaded tweeter, providing high output and wide dynamic range suitable for both two-channel music and home theater use. The KSP-400 includes high- and low-level inputs on the built-in subwoofer amplifier, allowing connection via speaker-level inputs or line-level/LFE from an AV receiver or processor. It is a bass-reflex design with a rear port, and is bi-wire capable at the main speaker terminals. Originally sold as a pair, the KSP-400 was offered in multiple real-wood veneer finishes and is known among Klipsch enthusiasts for delivering powerful, dynamic sound with deep, controlled bass for its size.
