The McIntosh PS1K Reference Subwoofer is an acoustic suspension column loudspeaker constructed with dual 13-inch multi-layer carbon fibre drivers, a 3.8-centimetre thick front baffle, and a solid machined aluminium base for reference stereo and multi-channel audio systems. Driven by two internal 500-watt Class D amplifiers delivering 1,000 watts of continuous output, the acoustic column energises large listening environments with low-frequency extension down to 20 Hz. Proprietary Low Distortion High Performance magnetic motor structures maintain linear excursion to ensure controlled, articulate bass reproduction during complex orchestral passages and high-output cinematic sequences.The Hi-Fi Centre Team TakeThe McIntosh PS1K Reference Subwoofer anchors expansive listening rooms with immense acoustic weight and absolute physical authority. Its sealed architectural column prevents structural cabinet colouration and eliminates turbulent port noise, creating an articulate, pitch-accurate foundation that integrates naturally into critical stereo listening. Even when reproducing substantial dynamic shifts, the acoustic column remains completely composed and inert, rendering subtle acoustic instruments and deep cinematic rumbles with equal poise. The illuminated output meter provides clear, real-time power monitoring, completing an authoritative low-frequency solution built for uncompromising performance.Key Acoustic & Design Features Dual Carbon Fibre Drivers: Multi-layer 13-inch diaphragms resist cone flexure during extreme excursions to produce clean, low-distortion bass. Kilowatt Amplification Engine: Twin Class D amplifiers deliver 1,000 watts of continuous power to sustain effortless dynamic headroom. Parametric Room Correction: Integrated parametric equalisation and adjustable crossover filters counteract troublesome room boundary reflections. Authorized Dealer Support: Hi-Fi Centre provides verified manufacturer warranty protection alongside qualified guidance from established audio specialists.
