PS1K

Powered Subwoofer

Experience bass excellence with the McIntosh PS1K Powered Subwoofer. Expertly engineered with a passion for audio excellence, the PS1K enhances your home audio system by delivering deeper, more precise low frequencies.

Design and construction of the PS1K embodies a no-compromise approach. At its core are two 13" woofers equipped with powerful magnets. These drivers feature our proprietary Low Distortion High Performance (LD/HP®) Magnetic Circuit Design, which significantly reduces distortion while boosting power handling and efficiency.

The woofers are designed for extreme linearity to minimize distortion, with an extra-long voice coil and a suspension system engineered for extended linear travel.

The PS1K features innovative multi-layer carbon fiber cones in the woofers. These cones provide unmatched rigidity and power handling. Unlike traditional single-layer carbon fiber cones, which could flex and degrade sound quality, the PS1K’s multi-layer design offers exceptional strength and resists flexing.

Feel the intensity of your favorite music and movies from the PS1K’s dual 13" woofers, with each powered by a 500 W Class D amplifier that combine to deliver up to 1,000 W of total output. These amplifiers are carefully calibrated to minimize distortion, delivering tight, clear bass even in large listening spaces.

The enclosure’s nearly 1½" (3.8 cm) thick baffle ensures rigidity and minimizes vibration, while the sealed box design eliminates port noise.

The PS1K’s sonic and visual synergy with McIntosh speakers is impeccable, but its powerful capabilities also make it an ideal match for high-output speakers from other manufacturers. The PS1K will easily keep pace with the main speakers in any high-end home audio or home theater system and is capable of maintaining performance at high volumes without compromise.

Built-in filtering controls let you fine-tune it to your listening preferences. Adjustable Low Pass and High Pass filters allow you to set the crossover frequency, while two fully adjustable parametric EQ filters help mitigate the effects of room acoustics and speaker placement. Level Control and Phase adjustment knobs ensure seamless blending of the PS1K’s output with your existing audio system.
