Klipsch KA-10Klipsch KA-1000-THX Power Amplifier

The Klipsch KA-1000-THX Amplifier is a high-performance subwoofer amplifier designed to deliver deep, accurate, and powerful bass for high-end home theater systems. Engineered to meet the demanding THX Ultra2 certification standards, this amplifier is the ideal power source for one or two Klipsch THX-certified subwoofers. With a combination of robust output, advanced tuning controls, and premium construction, the KA-1000-THX is an essential component for anyone seeking professional-grade low-frequency performance in a home audio environment.

Powerful, Clean Output

At the core of the Klipsch KA-1000-THX is a powerful Class D amplifier capable of delivering 500 watts of continuous power into an 8-ohm load and 1,000 watts into a 4-ohm load. This high output ensures that the connected subwoofers can reproduce low-frequency effects with exceptional clarity, authority, and minimal distortion. Whether you are listening to music, watching a movie, or playing a game, the KA-1000-THX delivers tight, impactful bass that adds depth and realism to the audio experience.

Its power reserves also allow for short bursts of even higher wattage to handle dynamic transients, such as explosions or deep bass drops, without straining or distorting. This makes it ideal for high-demand content like action films or orchestral scores.

THX Ultra2 Certification

As a THX Ultra2-certified amplifier, the Klipsch KA-1000-THX meets strict standards for low noise, low distortion, and highly accurate frequency response. This certification ensures that the amplifier can drive subwoofers to THX reference levels in large home theater rooms while maintaining absolute control and precision. This level of performance is critical for achieving cinematic-quality sound that replicates the original studio mix.

THX Ultra2 systems are tested for room size, output levels, and clarity, and the KA-1000-THX was specifically built to perform at this high level of fidelity. It pairs seamlessly with Klipsch KW-120-THX subwoofers, although it can power other subwoofer models that fall within its impedance range and performance requirements.

Advanced Controls and Customization

The Klipsch KA-1000-THX is equipped with a comprehensive set of controls that allow the user to tailor the bass response to their specific room and system setup. A continuously variable low-pass crossover ranging from 40 Hz to 120 Hz enables precise blending with the main speakers, ensuring a seamless transition between the subwoofer and the rest of the system.

A phase control knob (0 to 180 degrees) helps synchronize the subwoofer output with other speakers, minimizing phase cancellation and maximizing bass performance. Additionally, a boundary gain compensation switch adjusts the amplifier’s output to account for the acoustic reinforcement that occurs when a subwoofer is placed near a wall or corner. This feature ensures more balanced bass response in various room placements.

The KA-1000-THX also includes an auto-on/off feature, which allows the amplifier to power on when it detects an input signal and turn off after a period of inactivity. This helps conserve energy and extend the life of the unit without sacrificing convenience.

Durable Construction and Quality Components

This amplifier is built with premium-grade components designed for long-term reliability and high performance. A massive toroidal power transformer delivers clean, stable current to the internal circuitry, supporting consistent performance even during heavy use. The chassis is made of solid metal with a matte black finish, giving it a professional appearance that matches other high-end home audio gear.

The front panel features easy-to-use knobs and indicators, including level control, crossover setting, phase adjustment, and LED indicators for status and clipping. These controls are clearly labeled and accessible, making setup and calibration straightforward even for users who are not audio experts.

Flexible Connectivity

The Klipsch KA-1000-THX provides multiple input and output options to accommodate various system configurations. It includes RCA line-level inputs, allowing it to connect directly to AV receivers or processors. It also features pass-through outputs for daisy-chaining to additional subwoofer amplifiers or components, offering flexibility in larger setups.

Speaker-level connections are made via Neutrik Speakon connectors, which are known for their secure locking mechanism and ability to carry high current with minimal loss. This connection ensures reliable and efficient power delivery to the subwoofer enclosure(s).

Ideal Applications

The KA-1000-THX is ideal for large home theater rooms, dedicated media spaces, or high-fidelity music systems where powerful and controlled bass is essential. When paired with one or two high-performance subwoofers, it can reproduce the deepest notes with impact and finesse, enhancing everything from cinematic explosions to subtle low-end details in jazz and classical recordings.

Because of its scalability, users can start with a single subwoofer and add a second later for even greater bass presence. The amplifier’s high efficiency and thermal stability ensure it can operate quietly and reliably over long periods of use.

Summary

The Klipsch KA-1000-THX Amplifier is a purpose-built subwoofer amplifier that delivers reference-quality performance in demanding home theater environments. Its powerful output, precision controls, and rugged construction make it an excellent choice for audiophiles and home cinema enthusiasts who want to experience bass exactly as the creators intended. With its THX Ultra2 certification and high-end design, it stands out as a true performance leader in the world of subwoofer amplification.
