The Tannoy SGM 12 is a high fidelity, 2 way floorstanding loudspeaker that brings the legendary Tannoy Dual Concentric point source design to larger listening spaces, offering studio level performance in a home audio setting. Its 12″ Dual Concentric driver merges the mid bass cone and high requency tweeter on the same axis, resulting in coherent imaging, precise phase alignment, and remarkably natural sound dispersion across both vertical and horizontal planes. This design produces an expansive listening sweet spot and lifelike soundstage that helps instruments and vocals feel more present and real.
Built in a robust, high density cabinet with twin distributed ports, the SGM 12 delivers powerful, controlled bass with clean transients and minimal coloration, even at higher volume levels. User adjustable treble energy and treble roll off controls on the front panel let you tailor the speaker’s high frequency character to your room acoustics and listening tastes for more flexibility in different environments.
Premium components such as gold plated binding posts and a refined passive crossover network ensure excellent frequency balance and signal integrity, giving music lovers a rich, detailed, and engaging experience across genres — from orchestral and jazz to rock and electronic. The wide frequency response (approximately 38 Hz–30 kHz ±6 dB), 91 dB sensitivity, and compatible 20 – 250 W amplifier range make this speaker versatile for a variety of Hi Fi systems. Whether used for critical music listening or integrated into a home theater setup, the SGM 12 combines classic Tannoy heritage with modern acoustic engineering for an impressive blend of power and musicality.
