Klipsch THX-5002-S THX Ultra2 In-Ceiling Surround Speaker (Each) at Vinyl Sound Toronto Canada

The THX-5002-S is a THX Ultra2 Certified 2-way in-ceiling surround speaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Part of Klipsch's THX Cinema Series, it is the first in-ceiling surround speaker of its kind to receive the highly respected THX Ultra2 certification, validated for multi-channel reference playback in rooms of 3,000 cubic feet or larger. The speaker combines dual 5.25" Cerametallic Woofers operating in an enclosed tuned-port bass reflex chamber with dual 1" Titanium Tweeters in a patented 60-90-110° Variable Coverage Technology (VCT) horn, covering a measured frequency response of 45Hz to 20kHz (+/-3dB) at 93dB sensitivity and 8 ohms, with 100W continuous and 400W peak power handling. A dual-crossover network at 1200Hz and 1800Hz governs the driver integration. Wide Dispersion Surround Technology (WDST) creates enveloping sound fields and precise localization of effects. The 13.39" round drywall cutout and 9.23" mounting depth support standard ceiling joist cavity installations, and the speaker is fully timbre-matched to all other Klipsch THX-certified products.

Cinema Quality Sound: Cerametallic Woofers and Variable Coverage Technology Horn

The THX-5002-S employs dual 5.25" Cerametallic woofers operating in an enclosed tuned-port chamber, a bass reflex design using a 1.6" diameter front-mounted port to achieve the 45Hz lower extension while maintaining the woofers in a sealed acoustic environment. The Cerametallic cone material's superb damping characteristics prevent the cone from flexing or resonating at frequencies within the driver's operating range, resulting in consistent, controlled bass response regardless of the ceiling air space encountered during installation. This is a meaningful advantage in in-ceiling applications where the cavity volume above the ceiling varies from installation to installation and cannot be controlled as precisely as in a self-contained back-can design. The dual 1" titanium tweeters are mounted in a patented 7.5" x 3.75" horn with a 60-90-110° Variable Coverage Technology (VCT) profile, a skewed horn geometry that provides three distinct dispersion angles depending on the measurement axis. This horn shape allows the THX-5002-S to deliver precise imaging and localized sound fields for individual effects while simultaneously maintaining the broad coverage needed for surround channel use from a ceiling-mounted position, without the compromise between imaging precision and coverage breadth that conventional surround speaker horn designs must accept.

Wide Dispersion Surround Technology and THX Ultra2 System Integration

The THX-5002-S incorporates Klipsch's Wide Dispersion Surround Technology (WDST), which is designed specifically for surround and overhead channel positions in THX-certified home cinema systems. WDST uses the dual-tweeter array and VCT horn geometry to radiate high-frequency energy across a broader listening window than a conventional single-tweeter monopole in-ceiling design, creating the enveloping, immersive surround sound fields that distinguish cinema-quality audio from conventional multi-channel reproduction. WDST also gives the THX-5002-S substantially greater placement flexibility than conventional surround speakers, since the broader dispersion pattern compensates for off-axis seating positions that would otherwise be underserved by a directional monopole design. The dual-crossover network at 1200Hz and 1800Hz governs the transition between the Cerametallic woofer pair and the titanium tweeter array, and the THX-5002-S is spectrally matched to the full Klipsch THX Cinema Series including the THX-5002-L LCR speaker for tonal coherence across all channels in a complete THX Ultra2 in-ceiling home cinema build.

Frequently Asked Questions

What is the Klipsch THX-5002-S?

The Klipsch THX-5002-S is the first THX Ultra2 Certified in-ceiling surround speaker of its kind, featuring dual 5.25" Cerametallic woofers in a bass reflex tuned-port enclosure and dual 1" titanium tweeters in a patented 60-90-110° Variable Coverage Technology horn. It delivers a frequency response of 45Hz to 20kHz at 93dB sensitivity and 8 ohms, handling 100W continuous and 400W peak. Wide Dispersion Surround Technology creates enveloping sound fields for surround and overhead channel use, and the speaker is timbre-matched to all Klipsch THX Cinema Series products.

How does the Klipsch THX-5002-S differ from the THX-5002-L?

The Klipsch THX-5002-S and THX-5002-L are both THX Ultra2 Certified 2-way in-ceiling speakers from the same THX Cinema Series, sharing the same dual 5.25" Cerametallic woofer array, bass reflex tuned-port enclosure, 45Hz to 20kHz frequency response, 93dB sensitivity, 100W continuous power handling, and 13.39" cutout diameter. The critical difference is in the high-frequency driver configuration and intended channel role. The THX-5002-S uses dual 1" titanium tweeters in a vertically stacked 60-90-110° VCT horn with Wide Dispersion Surround Technology for surround and overhead channel use, producing a broader, more enveloping dispersion pattern suited to side, rear, and height channel positions. The THX-5002-L uses a single 1" titanium tweeter in a 45° skewed VCT horn for more directional LCR performance, where precise imaging and focused coverage of the listening area are the priority.

What is Variable Coverage Technology (VCT)?

Variable Coverage Technology is Klipsch's patented horn geometry used in the THX-5002-S's 7.5" x 3.75" high-frequency horn. The VCT horn profile varies the coverage angle along three measurement axes, producing 60°, 90°, and 110° dispersion angles depending on the direction measured. This asymmetric profile allows the horn to deliver precise directional imaging for localized sound effects in certain axes while maintaining broader dispersion for surround coverage in other axes, resolving the traditional design compromise between imaging precision and broad coverage breadth in a single horn structure. In the THX-5002-S's surround speaker role, VCT allows the dual titanium tweeters to produce both the pinpoint localization needed for object-based audio placement in Dolby Atmos and DTS:X and the enveloping coverage needed for ambient surround field reproduction.

Can the Klipsch THX-5002-S be used for Dolby Atmos height channels?

Yes, the Klipsch THX-5002-S is suitable for overhead height channel positions in Dolby Atmos and DTS:X object-based audio systems in addition to its design role as a side and rear surround speaker. Its THX Ultra2 certification, 45Hz to 20kHz full-range capability, and wide dispersion horn make it capable in ceiling-mounted height channel positions where height effects are directed downward at the listening area. Its WDST dual-tweeter design also makes it effective for multiple overhead seating positions simultaneously. For the most accurate height effect reproduction in high-performance Atmos systems, some installers prefer in-ceiling speakers with angled baffles that direct sound toward the primary listening position rather than straight down, though the VCT horn's broad dispersion partially compensates for this in flat-baffle configurations.

What amplifier or AV receiver is compatible with the Klipsch THX-5002-S?

The Klipsch THX-5002-S operates at 8 ohms with 93dB sensitivity and handles 100W continuous and 400W peak per channel. Any AV receiver or separate power amplifier capable of stable 8-ohm operation is compatible. For rooms of 3,000 cubic feet or larger where the THX Ultra2 certification is applicable, a THX Ultra2 certified AV receiver or a dedicated multichannel power amplifier from brands such as Anthem, Parasound Halo, or Emotiva XPA with at least 100W per channel at 8 ohms will extract the best dynamic capability from the THX-5002-S. THX Ultra2 certified receivers from Denon, Marantz, and Yamaha are validated as matched systems with THX Ultra2 certified speakers.
