Tannoy Canterbury GR-OW 15 inch Dual Concentric HiFi Speaker – Oiled Walnut

The Tannoy Canterbury GR‑OW 15″ Dual Concentric HiFi Loudspeaker is a flagship‑level floorstanding speaker that combines classic British sound engineering with refined modern acoustic advancements to deliver an exceptionally detailed and engaging audio experience. At its core is a powerful 15″ Dual Concentric driver system, where the bass and treble drivers share a single acoustic centre, producing coherent imaging, natural phase alignment, and rich, lifelike sound dispersion across a broad listening area. This driver incorporates advanced materials and precision design to offer outstanding clarity and articulation — especially in the midrange and high frequencies — while maintaining deep, authoritative bass extension with minimal distortion.

Housed in a substantial oiled walnut veneer cabinet with solid walnut trim and heavy internal bracing, the Canterbury GR‑OW’s enclosure uses a dual variable distributed port design to optimise airflow, improve transient response, and extend low‑frequency performance with punch and control. The crossover network features high‑quality components, adjustable shelving, and time‑compensated circuitry that allows fine‑tuning of the sound to suit room acoustics and listening preferences.

With a 96 dB sensitivity, 8 Ω nominal impedance, and recommended amplifier power between 20 W and 300 W RMS, this speaker pairs well with a wide range of high‑fidelity amplifiers, from powerful solid‑state units to tube and hybrid designs. The result is an immersive listening experience marked by dynamic impact, refined detail, and expansive soundstage depth — ideal for serious audiophiles and music lovers seeking studio‑like performance in home environments.
