The Klipsch THX-5002-S In-Ceiling Speaker is a purpose-built architectural surround speaker designed to create an expansive, immersive sound field while remaining almost completely hidden within the ceiling. THX Ultra2 Certified and engineered around Klipsch Wide Dispersion Surround Technology, the THX-5002-S combines dual 5.25-inch Cerametallic woofers with two horn-loaded 1-inch titanium tweeters to deliver the dynamics, clarity, and broad dispersion required for high-performance home cinema.
Where the THX-5002-L emphasizes precise imaging and localized sound, the THX-5002-S is optimized for enveloping surround reproduction. Its two titanium tweeters are mounted in vertically stacked Tractrix horns to distribute high-frequency information throughout a larger listening area. Dual Cerametallic woofers operate in an enclosed tuned-port chamber for consistent bass performance independent of the surrounding ceiling cavity, making the THX-5002-S a powerful solution for concealed side-, rear-, and other surround-channel applications.
Key Features & Innovations
THX Ultra2 Certified performance — the Klipsch THX-5002-S In-Ceiling Speaker is engineered for demanding multichannel movie and music systems and is part of Klipsch's THX Ultra2 architectural speaker family.
Wide Dispersion Surround Technology — Klipsch WDST is designed to combine an enveloping surround field with effective localization of individual effects, providing greater placement flexibility than a conventional direct-radiating design.
Dual 1-inch titanium tweeters — two high-frequency drivers provide the foundation for the THX-5002-S's specialized surround dispersion pattern while offering the speed, detail, and efficiency required for cinematic playback.
Vertically stacked Tractrix horns — each titanium tweeter is horn loaded, with the vertically arranged horn system distributing high-frequency information throughout a broad listening area.
Dual 5.25-inch Cerametallic woofers — Klipsch's rigid, lightweight Cerametallic cones provide excellent damping characteristics for controlled midrange and bass reproduction at demanding playback levels.
Enclosed tuned-port woofer chamber — the woofers operate within their own engineered enclosure, helping maintain consistent bass performance regardless of the size or construction of the surrounding ceiling cavity.
93dB sensitivity — high efficiency allows the THX-5002-S to achieve substantial output while making effective use of available amplifier power.
100W continuous / 400W peak power handling — substantial dynamic capability makes the speaker suitable for high-performance home theaters using capable AV receivers or separate multichannel power amplifiers.
45Hz–20kHz frequency response — broad bandwidth provides impressive low-frequency extension for an architectural surround speaker while allowing seamless integration with a dedicated theater subwoofer system.
Front-flush bass-reflex port — the enclosed woofer chamber vents through a 1.6-inch-diameter port that terminates at the front of the speaker, allowing the tuned bass-reflex system to operate properly after installation.
Timbre-matched THX Cinema Series — the THX-5002-S is designed to integrate with Klipsch's other THX-certified in-wall and in-ceiling products for consistent sonic character throughout a concealed theater system.
Edge-to-edge magnetic grille — the low-profile grille uses neodymium magnets for secure attachment and can be painted to coordinate with the surrounding ceiling.
FAQ — Klipsch THX-5002-S
What is the THX-5002-S designed for?
The THX-5002-S is designed primarily for surround-channel applications in high-performance home theaters. Its dual-tweeter Wide Dispersion Surround Technology architecture distributes surround information throughout a broad listening area, helping create a more enveloping cinematic sound field.
What is Klipsch Wide Dispersion Surround Technology?
Klipsch Wide Dispersion Surround Technology, or WDST, uses multiple horn-loaded high-frequency drivers to create a broad surround field while preserving useful localization of individual effects. This design also provides greater placement flexibility than a conventional direct-radiating speaker.
How is the THX-5002-S different from the THX-5002-L?
The THX-5002-S is optimized for diffuse surround reproduction and uses two 1-inch titanium tweeters in vertically stacked Tractrix horns. The THX-5002-L uses a single titanium tweeter in a 45-degree skewed Variable Coverage Technology horn and is designed for more precise imaging and localized sound. Both models use dual 5.25-inch Cerametallic woofers and are THX Ultra2 Certified.
How much amplifier power can the THX-5002-S handle?
The THX-5002-S is rated for 100 watts continuous and 400 watts peak. Its 93dB sensitivity allows it to achieve substantial output with compatible AV receivers and multichannel power amplifiers.
Does the THX-5002-S have its own enclosure?
Yes. The dual Cerametallic woofers operate within an enclosed tuned-port chamber. This helps provide consistent bass response regardless of the size or construction of the ceiling cavity surrounding the speaker.
Can the THX-5002-S be used with the THX-8000-L and THX-8000-S?
Yes. Klipsch designed the THX-5002-S to be timbre matched with its other THX-certified speakers. It can therefore be integrated with models such as the THX-8000-L and THX-8000-S when designing a complete concealed home theater system.
