Tannoy Westminster Royal GR-OW Floorstanding HiFi Loudspeaker, 15 Inch Dual Concentric, Oiled Walnut

The Tannoy Westminster Royal GR‑OW Floorstanding HiFi Loudspeaker is a flagship-class 2-way floorstanding loudspeaker that represents the pinnacle of Tannoy’s British hi-fi engineering and craftsmanship. At its heart is a 15″ Dual Concentric driver featuring a large low-frequency paper cone with a concentric aluminium-magnesium high-frequency compression dome and PepperPot WaveGuide for symmetrical, wide-dispersion sound — delivering superb imaging, natural tonal balance and immersive musical realism suitable for large listening spaces.

Built around a compound horn-loaded enclosure, the Westminster Royal GR-OW boasts a massive 530 L internal volume with extensive internal bracing and Differential Materials Technology (DMT) to minimise resonances and improve bass control. This design, combined with horn loading and high sensitivity (≈99 dB), produces effortless dynamics, deep extension down to ~18 Hz and stunning full-range articulation with power handling up to 700 W peak.

Handcrafted with meticulous attention to detail, the cabinet sports a luxurious oiled walnut veneer with hand-selected burr walnut inlays, solid walnut trim and precision machined gold-anodised metal accents, making these speakers as striking visually as they are sonically. The bi-wireable binding posts and fifth grounding connection ensure excellent signal integrity, while the included Prestige wood wax and accessory pack underscore Tannoy’s commitment to a premium ownership experience.

Designed and manufactured in the UK, the Westminster Royal GR-OW combines the best of classic Dual Concentric point-source technology with modern material science and acoustic engineering, producing lifelike soundstages, effortless dynamics, and musical detail that reveals texture, ambience and scale in every genre.
