Klipsch THX-1200-SW

Ultra-Powerful Passive Subwoofer Klipsch THX-1200-SW

The Klipsch THX-1200-SW is a passive subwoofer designed to deliver high-quality acoustic performance in dedicated home theater rooms. Equipped with a 30.5 cm diameter speaker featuring a Cerametallic cone and an aluminum cast frame, this subwoofer generates powerful and deep bass.

Paired with the dedicated Klipsch KA-1000-THX amplifier, a pair of THX-1200-SW subwoofers can reach a sound pressure level of 130 dB at 30 Hz and 122 dB at 20 Hz. This allows you to physically feel the impact of the most extreme low frequencies during your home cinema sessions.

A Front Laminar Vent for Distortion-Free Bass

The bass-reflex design of the Klipsch THX-1200-SW incorporates a front laminar vent that optimizes airflow and sound pressure towards the listener. This technology delivers powerful and deep bass while minimizing turbulence noise and distortion, even at high volumes.

The result: exceptionally clear and clean low-frequency sound that respects the dynamics of the most demanding soundtracks. Explosions, impacts, rumbles—the reproduction is both ample and precise.

A High-Performance Speaker

At the heart of the THX-1200-SW subwoofer is a 30.5 cm diameter woofer with exceptional characteristics. Its Cerametallic cone, an exclusive material developed by Klipsch, combines lightness and rigidity for optimal transient response.

The cast aluminum frame ensures impeccable mechanical stability, while the 6.8 kg ceramic magnetic structure provides a powerful and uniform magnetic field for precise control of the diaphragm’s movements. A speaker designed to handle the subwoofer’s 1500 W capacity without flinching.

A Robust Cabinet for Performance

To make the most of this exceptional equipment, Klipsch has housed the speaker in a perfectly optimized cabinet. Made from MDF (medium density fiberboard), a dense and inert material, it provides a stable environment free from parasitic resonances.

With generous volume and internal reinforcements, the THX-1200-SW’s cabinetry forms a solid base that allows the speaker to perform at its best. The sleek shapes and textured black Galaxy finish integrate stylishly into any interior.

Connectivity and Amplification

The Klipsch THX-1200-SW subwoofer is a passive model that requires external amplification to operate. It has been specifically designed to pair with the Klipsch KA-1000-THX amplifier to form a perfectly synergistic duo.

The connection between the two components is made via robust speaker terminals that allow for bi-wiring or bi-amplification. With a nominal impedance of 8 ohms, the subwoofer is easy for the amplifier to drive and can even operate in tandem on a single KA-1000-THX.

Extended Frequency Response

Thanks to the combination of its high-performance speaker, tuned front vent, and generous volume, the Klipsch THX-1200-SW delivers a frequency response down to 20 Hz at ± 3 dB.

A feat that allows it to effortlessly reproduce the deepest octaves, from extreme sub-bass to low-midrange. Coupled with high-quality front and surround speakers, it provides a spectacular foundation for all your movies and music.

A THX Ultra2 Certified Subwoofer

The THX-1200-SW proudly carries the THX Ultra2 certification, a demanding label that guarantees superior acoustic performance for high-end home theater installations. Klipsch engineers worked closely with the THX teams to optimize this subwoofer according to stringent criteria.

Frequency response, power handling, low distortion—the Klipsch THX-1200-SW meets all the necessary conditions to reproduce soundtracks as intended by filmmakers and sound engineers. A guarantee of quality and fidelity.

What are the dimensions of the Klipsch THX-1200-SW subwoofer?
