•⁠  ⁠Product Overview – PMC PB1i, released in 2006, is a reference three-way floorstanding loudspeaker using advanced transmission line technology to deliver exceptional bass depth, scale, and studio-grade accuracy.

•⁠  ⁠Acoustic Design – Featuring PMC’s ATL transmission line, soft-dome midrange, and precision tweeter, the design offers extended low-frequency response, controlled dispersion, and effortless dynamics for realistic, full-range reproduction.

•⁠  ⁠Sound Performance – PMC PB1i delivers authoritative bass, highly articulate midrange, and smooth high frequencies, excelling in soundstage scale, tonal neutrality, and dynamic realism suited to high-resolution systems.

•⁠  ⁠Specifications – Nominal impedance is 8 ohms with a sensitivity of approximately 90 dB, recommended amplification from 30–300 watts, and a frequency response extending down to roughly 28 Hz.

•⁠  ⁠Dimensions – Each cabinet measures approximately 1040 mm (H) × 330 mm (W) × 450 mm (D), designed for optimal internal line length and stable floorstanding placement.

•⁠  ⁠Weight – Each speaker weighs approximately 47 kg, reflecting the heavily braced enclosure, long transmission line loading, and high-mass construction for resonance control.

• Omnidirectional Design Overview – The German Physiks HRS-120, introduced in the mid-2010s, features the renowned DDD omnidirectional driver, delivering a seamless 360-degree soundstage with exceptional coherence, natural dispersion, and remarkable room-filling realism.

• Advanced DDD Driver Technology – The German Physiks HRS-120 uses a carbon-fibre bending-wave DDD transducer, producing wide bandwidth, low distortion, and superior transient accuracy, enabling highly convincing holographic imaging and lifelike spatial presentation.

• High-Performance Bass System – A precision-engineered downward-firing woofer and tuned cabinet alignment ensure deep, articulate low frequencies, giving the HRS-120 authoritative bass integration without sacrificing speed, clarity, or overall musical balance.

• Room-Friendly Loudspeaker – With its wide dispersion characteristic, the German Physiks HRS-120 maintains consistent tonal accuracy throughout the room, minimizing placement challenges and offering an immersive listening experience from nearly any position.

• Dimensions – Approx. 1,050 mm (H) × 280 mm (W) × 280 mm (D). The compact footprint and tall, elegant enclosure make it suitable for medium to large listening spaces.

• Weight – Approx. 32 kg per speaker, providing solid cabinet stability that reduces resonance and supports the precision operation of the DDD driver system.

• Quad 22L – A refined floorstanding loudspeaker known for its smooth tonal balance, articulate midrange, and engaging musicality, designed to deliver a natural, non-fatiguing presentation across diverse listening rooms.

• Dual-Driver Precision – Utilises a dedicated soft-dome tweeter and twin Kevlar mid/bass drivers, providing excellent clarity, controlled dispersion, and enhanced coherence for both vocal accuracy and full-range musical reproduction.

• Room-Friendly Design – Rear-ported enclosure enables flexible placement while maintaining solid low-frequency extension and rhythmic control, making it suitable for medium to large listening environments.

• Timeless Build Quality – High-quality cabinet construction with beautifully lacquered finishes offers reduced resonance, strong structural rigidity, and an elegant aesthetic aligned with Quad’s British engineering philosophy.

• Dimensions – Stands approximately 872 mm (H) × 203 mm (W) × 280 mm (D), optimised for stable floor placement and proper driver height relative to seated listening position.

• Weight – Each speaker weighs around 18 kg, providing the necessary mass for reduced cabinet vibrations and improved acoustic performance.
