About the S2
The Quad S-2 bookshelf speakers embody Quad's 'Closest Approach To The Original Sound' philosophy. This two-way, bass-reflex design pairs a 125mm (5") woven Kevlar cone mid/bass driver with a 12 x 45mm (0.5" x 1.75") true ribbon tweeter, delivering open highs, precise midrange, and surprisingly extended bass from a compact cabinet. The ribbon tweeter uses sandwich construction for robustness and acts as both voice coil and radiator, ensuring smooth response beyond human hearing. Rear-firing port augments low frequencies, with sophisticated crossover at 3kHz for seamless integration. Available in finishes like Black Oak, Sapele Mahogany, Piano Black, or White. Bi-wire/bi-amp capable with dual binding posts and removable grilles. Ideal for stands 24-28 inches high.
