About the Klipsch KL-650-THX

Professional-grade THX home theater sound
Professional-grade THX home theater sound
Klipsch engineered the KL-650-THX to give you intense, realistic movie theater sound in your home using the same technology found in their professional-grade cinema speakers. This speaker bears the THX Ultra2 seal of approval, which means it can deliver crisp, clear output at highly demanding reference levels in rooms as large as 3,000 cubic feet. Use three of these speakers across your home theater's front soundstage for engaging dialogue and gripping sound effects.

Use the KL-650-THX to create an awesome speaker array for your ultimate THX Ultra2 home theater.
Horn technology for focused sound
The KL-650-THX uses a 1" titanium dome compression driver paired with Klipsch's Tractrix® horn. This large, rectangular flared opening projects high frequencies toward your listening area and prevents sound waves from simply spilling out in all directions. The horn design helps the speaker reproduce accurate detail with everything you listen to, while reducing reflections that can color the sound. The horn also improves dynamics and efficiency, for powerful, "front row" sound that remains crystal clear at all volume levels. Two 6-1/4" Cerametallic™ anodized aluminum woofers pump out detailed, low-distortion mids and powerful bass.
Built for the long haul
To ensure years of top-notch performance, Klipsch builds their THX certified speakers to the highest standards. Each ported enclosure features the same interlocking panel construction found in their professional speakers for maximum structural integrity and strength. Premium-quality internal wiring is used throughout for superior signal transfer and clarity. And Klipsch finishes off the KL-650-THX with a beautiful and durable fascia of black brushed aluminum.
Meet the whole family
An ideal choice for each of your home theater's front channels, the KL-650-THX can also be used for surround speakers, or for combination home theater/music systems that demand superb sound and high-output capability. To complete the THX Ultra2 system of your dreams, add two KS-525-THX surround sound speakers for spacious rear-channel effects, and a KW-120-THX subwoofer and KA-1000-THX subwoofer amplifier combo for deep, high-impact bass.
