Klipsch THX-5000-SUR Surround Speakers (Pair) at Vinyl Sound Toronto Canada

The THX-5000-SUR is a THX Ultra2 Certified surround loudspeaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Built on the same engineering foundation as Klipsch professional cinema systems, this speaker pair brings reference-level home theater immersion to demanding 5.1, 6.1, and 7.1-channel installations. Powered by Wide Dispersion Surround Technology (WDST), it combines dual 5.25-inch Cerametallic cone woofers with dual 1-inch titanium-dome compression driver tweeters loaded by 5-inch square 90° x 60° Tractrix Horns, delivering a sensitivity of 96 dB at 2.83V/1m and handling up to 100 watts RMS continuous.

Wide Dispersion Surround Technology (WDST)

WDST is Klipsch's no-compromise engineering approach to surround speaker design. Unlike conventional surround designs that force a trade-off between diffuse coverage and pinpoint localization, WDST delivers both simultaneously. The array positions each woofer and tweeter set on an angled baffle facing opposite the other, with tweeters oriented diagonally to minimize interference between their outputs. The result is a deep, enveloping surround sound field normally associated with diffuse-radiating speakers, combined with the precise effect localization characteristic of direct-radiating models. Listeners are fully immersed in the soundstage without sacrificing placement flexibility during installation.

Tractrix Horn-Loaded Tweeters and Cerametallic Woofers

The 5-inch square 90° x 60° Tractrix Horns load each 1-inch titanium-dome compression driver for controlled, low-distortion high-frequency dispersion. These are the identical tweeters used in the THX-6000-LCR and THX-5000-LCR speakers, guaranteeing tonal continuity from the front channels through to the surrounds. The two 5.25-inch Cerametallic cone woofers, cast in aluminium frames with neodymium magnet structures and magnetic shielding, reproduce midrange and bass with exceptional stiffness-to-mass ratios down to 80 Hz. Matching the woofer driver used in the THX-5000-LCR ensures a cohesive, seamless sound field across the entire system.

Professional-Grade Construction and Mounting Flexibility

The sealed MDF enclosure uses dado and rabbet joinery, the same cabinet construction method employed in Klipsch's professional cinema loudspeakers, to maximize rigidity and minimize resonance even in ceiling-suspended installations. The Galaxy Black cabinet with black anodized aluminum fascia integrates cleanly into custom home theater environments. On the rear panel, vertically aligned keyholes and dual 1/4"-20 threaded inserts accept any wall or ceiling mount rated for 20 lbs or more, giving installers broad placement flexibility. Dual binding posts support bi-amping or bi-wiring configurations, and all internal wiring is top-of-the-line to preserve signal purity from amplifier to driver.

Frequently Asked Questions

What is the Klipsch THX-5000-SUR?

The Klipsch THX-5000-SUR is a THX Ultra2 Certified two-way surround loudspeaker sold as a pair, featuring dual 5.25-inch Cerametallic woofers, dual 1-inch titanium-dome tweeters on Tractrix Horns, and a sensitivity of 96 dB at 2.83V/1m. It uses Klipsch's proprietary Wide Dispersion Surround Technology (WDST) to deliver both enveloping surround coverage and precise localization of audio effects. Designed for high-performance 5.1, 6.1, and 7.1-channel home theaters, the THX-5000-SUR draws directly from Klipsch's professional cinema loudspeaker engineering, built in Indianapolis, Indiana, USA.

How does the Klipsch THX-5000-SUR compare to the Klipsch THX-5000-LCR?

The THX-5000-SUR and the THX-5000-LCR share the same Cerametallic woofer driver, ensuring tonal matching between the front LCR channels and the surrounds. The THX-5000-LCR is engineered for left, center, and right front-channel use and employs a single Tractrix Horn configuration optimized for forward-facing direct radiation. The THX-5000-SUR is purpose-built for surround duty, using the WDST array with two angled woofer and tweeter sets to produce both diffuse and localized sound from a single enclosure. For competitors, the Klipsch THX-5000-SUR occupies a similar market position to speakers such as the Triad InRoom Gold LCR Surround and JBL Synthesis SCL-4, but distinguishes itself through THX Ultra2 certification and the proprietary WDST dual-horn array.

Can the Klipsch THX-5000-SUR be used in a 7.1-channel system?

Yes, the Klipsch THX-5000-SUR is fully compatible with 5.1, 6.1, and 7.1-channel home theater configurations. Its THX Ultra2 certification covers all of these channel formats, and the WDST design ensures each speaker provides adequate coverage and localization regardless of placement position in a multi-surround layout. For 7.1 setups, two pairs of the THX-5000-SUR can be deployed at the side and rear surround positions for a fully THX-matched surround field.

What is Wide Dispersion Surround Technology (WDST)?

Wide Dispersion Surround Technology (WDST) is a proprietary Klipsch surround speaker design that combines two angled woofer and tweeter baffles within a single enclosure, oriented in opposing directions. WDST eliminates the traditional choice between diffuse-radiating and direct-radiating surround designs by delivering both simultaneously. Listeners receive the deep, room-filling surround field of a dipole or bipole design alongside the precise effect localization of a direct-radiating speaker, all from a speaker with significantly more placement flexibility than conventional surround designs.

Where can I buy the Klipsch THX-5000-SUR in Toronto or Canada?

The Klipsch THX-5000-SUR Surround Speakers are available at Vinyl Sound, located in Toronto, Canada. Vinyl Sound is an authorized Klipsch dealer serving customers across Toronto and the Greater Toronto Area, as well as customers across Canada. Purchasing from an authorized Canadian dealer ensures full manufacturer warranty support and access to Klipsch's certified service network.

What amplifier power does the Klipsch THX-5000-SUR require?

The Klipsch THX-5000-SUR handles up to 100 watts RMS continuous and 400 watts peak, with a nominal impedance of 8 ohms. Its 96 dB sensitivity rating means it achieves high output levels from relatively modest amplifier power, making it compatible with a wide range of AV receivers and dedicated multichannel amplifiers. For a THX Ultra2 reference-level system, Klipsch recommends pairing the THX-5000-SUR with an amplifier or AV receiver rated for at least 20 watts per channel into 8 ohms, though the high sensitivity ensures excellent performance with significantly more power on tap.

Can the Klipsch THX-5000-SUR be ceiling mounted?

Yes, the Klipsch THX-5000-SUR supports both wall and ceiling mounting. The rear panel includes vertically aligned keyholes for keyhole-bracket wall installation and dual 1/4"-20 threaded inserts compatible with standard Omni-Mount hardware and any quality wall or ceiling mount rated for 20 lbs or more. The sealed dado and rabbet MDF enclosure maintains structural integrity in suspended ceiling applications, and the compact footprint of 13.75 x 13 x 8.5 inches allows flexible positioning in rooms where wall mounting is not practical.

Does the Klipsch THX-5000-SUR support bi-wiring or bi-amping?

Yes, the Klipsch THX-5000-SUR includes two sets of binding post speaker terminals connected via brass strap jumpers, fully supporting bi-wiring and bi-amping configurations. Bi-amping allows a separate amplifier channel to drive the woofers and tweeters independently, and bi-wiring provides separate cable runs to each section while using a single amplifier channel. Both configurations can improve separation between the high-frequency and low-frequency signal paths for audiophile-grade installations.
