Experience big theater sound at home

The Klipsch KL-525-THX loudspeaker delivers all the power, detail and emotional impact you'd expect at a big, high-end movie theater or a live concert — only sized just right to enjoy in the comfort of your home. That's because Klipsch uses the same technology found in their professional-grade cinema speakers to help give the KL-525-THX its intense, realistic sound. This speaker bears the THX Ultra2 seal of approval, which means it can produce crisp, clear output at highly demanding reference levels in rooms as large as 3,000 cubic feet. Make these compact powerhouses the centerpiece of your own ultimate THX system for a big step up in home theater performance.

Horn technology for focused sound

The KL-525-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 5-1/4" Cerametallic™ anodized aluminum woofers pump out detailed, low-distortion mids and bass.

Built for the long haul

To ensure years of top-notch performance, Klipsch builds their THX certified speakers to the highest standards. Each sealed 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-525-THX with a beautiful and durable fascia of black brushed aluminum.

Meet the whole family

The Klipsch KL-525-THX makes an ideal speaker for each of your home theater's front left, center, and right channels. It can also be used for surround channels, 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.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Product Research


LCR Speaker: The Klipsch KL-525-THX is a THX Ultra2 certified LCR loudspeaker designed primarily for front left-, center-, and right-channel reproduction in high-performance home theaters. It can also be used for surround and surround back channels. The KL-525-THX is equally suitable for combination home theater & music systems demanding superb sound and high output capability.

THX Ultra2 Certification: Because of its THX Ultra2 certification, the Klipsch KL-525-THX LCR loudspeaker works well with multichannel movie and music presentations playing up to reference levels in rooms of 3,000 cubic feet or larger.

Two-Way Design: The Klipsch KL-525-THX LCR loudspeaker employs a two-way speaker design with a 1" titanium dome compression driver mated to a 6"x10" Tractrix Horn and  dual 5.25" Cerametallic woofers.

  • Tractrix Horn Tweeter: The KL-525-THX loudspeaker features a professional-grade 1" titanium-diaphragm compression driver inside a rectangular 6"x10" Tractrix Horn for smoother high-end response with greater extension, enhanced imaging, and more powerful dynamics. The Tractrix Horns delivers a 90° wide and 60° high dispersion pattern for a broader sound-stage. Behind each horn lies a 1" titanium tweeter with a linear travel suspension for open, natural, sound.
  • Cerametallic Woofer: The dual 5.25" woofers of the KL-525-THX feature Klipsch's distinctive, copper-colored Cerametallic cones. Made with an anodized aluminum, these cones are strong and dent resistant. The anodizing process converts their inner and outer surfaces to ceramic. The outcome is a rigid cone with superb damping characteristics that will not flex or resonate at frequencies within the woofer's operating range. The dual 5.25" woofers also employ a rubber surrounds for added durability.

Crossover Network: For signal purity and perfect driver integration, the 1500Hz crossover on the KL-525-THX features the finest components and Klipsch custom internal wiring.

Sealed MDF Enclosure: Construction is to the highest standard, with a professional-grade rabbet and dado locked panel cabinet made from MDF (medium density fiberboard). For additional rigidity, the front baffle is constructed of anodized aluminum.

Dual Binding Posts: The KL-525-THX speaker has two sets of binding posts connected by jumpers. Using the dual binding posts, you can bi-amp or bi-wire the speakers. The binding post terminals will accept banana plugs (single or dual), pin-connectors, spade-connectors, and bare wire.

Mounting Options: The KL-525-THX  includes four self-adhesive rubber feet that help secure it to your stand or shelf. The rubber feet added 0.3125" to the height of the speaker. The LCR speaker's size and weight prevents the speaker from being wall-mounted.
