NO-COMPROMISE DESIGN

The McIntosh PS1K is a no-compromise subwoofer that embodies excellence in both design and functionality. At its heart are two 13-inch woofers, designed with Low Distortion High Performance (LD/HP®) Magnetic Circuit technology. This innovation significantly reduces distortion while increasing power handling and efficiency, ensuring precise and powerful bass.

The use of Finite Element Analysis (FEA) optimizes the woofer design, ensuring exceptional linearity and extended linear travel for superior bass performance. The woofers' multi-layer carbon fiber cones—far more rigid than traditional single-layer designs—ensure outstanding strength and resistance to flexing, even during intense, extended use.

FEEL THE SOUND

With dual 13” woofers, each powered by a 500-watt Class D amplifier, the PS1K delivers up to 1,000 watts of total output. These amplifiers are finely tuned to minimize distortion, providing tight, clear, and immersive bass even in larger listening rooms. The nearly 1.5-inch-thick baffle adds rigidity and minimizes vibration, while the sealed box design eliminates any unwanted port noise.

VERSATILITY FOR EASY SYSTEM INTEGRATION

The McIntosh PS1K stands out for its versatility, designed to integrate seamlessly into a variety of audio setups—whether a two-channel stereo system or a full multi-channel home theater. Its extensive connection options include balanced stereo inputs/outputs and balanced and unbalanced subwoofer inputs/outputs, allowing flexibility for different installations. Multiple PS1K subwoofers can be daisy-chained for larger systems.

Once integrated into your system, the PS1K’s built-in controls enable fine-tuning for your space and preferences. Low Pass and High Pass filters, along with adjustable parametric EQ filters, allow users to adjust the crossover frequency and address room acoustics and speaker placement. Level Control and Phase adjustment knobs ensure perfect blending of the PS1K’s output with your existing speakers.

BUILT-IN PROTECTION FOR A LIFETIME OF LISTENING

McIntosh prioritizes longevity with advanced protection features. Power Guard® technology prevents audio clipping, adjusting the input signal instantly to ensure no distortion occurs. Sentry Monitor™, a fuse-less short-circuit protection, safeguards the amplifier by disconnecting the output stage if current levels become unsafe, resetting automatically when conditions stabilize.

HARMONY OF SOUND, SIGHT, AND CONVENIENCE

The McIntosh PS1K is more than a powerhouse of sound—its high-gloss black finish, carbon trim, and aluminum base make it a perfect visual companion to McIntosh’s XRT2.1K and XRT1.1K speakers. Equipped with Power Control technology, the PS1K can turn on and off seamlessly with other McIntosh components, and eco-friendly signal sensing ensures efficient power use. For added convenience, glide feet and spikes ensure perfect placement on any floor surface.
