The PMC10‑4 XBD is a dual‑cabinet, 3‑way active reference monitor that combines PMC’s classic QB‑series architectural philosophy with next‑generation ATL™ transmission‑line technology, delivering up to 9.6 kW of class‑D amplification, extreme SPL capability, ultra‑low‑frequency authority and forensic‑grade detail for elite studios. Design Heritage Meets Modern Innovation The PMC10‑4 XBD builds on the iconic QB1 visual language created with Capitol Studios, preserving the timeless aesthetic while integrating advanced features. Two ATL™ Advanced Transmission Line cabinets house eight 10‑inch ultra‑long‑throw low‑frequency drivers, each paired with dedicated power20 amplifiers, ensuring tight, controlled bass that extends deep without sacrificing speed. The mid‑high section retains the revered 34 mm soft‑dome tweeter and PMC75v3 midrange, now enhanced with the proprietary n‑compass™ waveguide for consistent dispersion, phase coherence and tonal uniformity across the listening environment. Power Architecture and DSP Control At the heart of the system lies the in‑house Master36 DSP/Amplifier unit, which supplies 800 W to each tweeter and midrange and orchestrates the three power20 amplifiers that drive the eight bass drivers (four pairs receive 1 000 W each). The combined output reaches an astonishing 9.6 kW, providing ample headroom for extreme SPLs while maintaining pristine clarity. Optimised cross‑overs, transparent system protection and comprehensive room‑EQ are delivered via the SoundAlign2 interface, allowing engineers to align the monitors precisely without compromising signal integrity. All inputs support analogue and digital connections up to 192 kHz. Physical Specifications Each cabinet measures 820 mm × 1 040 mm × 523 mm (plus a 10 mm LF driver surround) and weighs 140 kg (master) and 130 kg (SUB‑XBD). The effective ATL™ line length totals 2 × 3.4 m (11.2 ft), contributing to the unparalleled low‑frequency response. The system’s robust construction and illuminated status LEDs provide clear visual feedback during operation. Why Choose the PMC10‑4 XBD Unmatched Bass Authority: Eight 10‑inch drivers and 9.6 kW of class‑D power deliver deep, controlled low‑end that remains articulate at high SPLs. Reference‑Grade Clarity: Soft‑dome tweeter and PMC75v3 midrange, refined with n‑compass™ waveguide, ensure micro‑detail and phase‑accurate imaging. Advanced DSP Alignment: SoundAlign2 offers intuitive room‑EQ and crossover optimisation, guaranteeing accurate translation of mixes. Heritage Design, Modern Build: Classic QB‑series aesthetics combined with state‑of‑the‑art ATL™ transmission‑line engineering. Scalable Power Management: Dedicated Master36 and power20 amplifiers provide independent control and redundancy for reliable studio performance.
