The Diamond 12.C is a dedicated centre-channel speaker — the dialogue anchor of a Diamond 12 home cinema system. A sealed two-way design with twin 130 mm (5") woven-cone drivers flanking a 25 mm textile-dome tweeter, it delivers clear, intelligible speech that stays locked to the screen.Unlike the ported models in the range, the 12.C uses a closed-box (sealed) enclosure for tight, controlled output ideal for dialogue, crossing over at 2.2 kHz across a 90 Hz – 20 kHz response. Its 90 dB sensitivity — the highest in the series — and 8 Ω nominal impedance (4 Ω minimum) make it an easy, efficient match for any AV receiver from 20 to 120 W.Voice-match it with any Diamond 12 pair — the 12.1 or 12.2 standmounts, or the 12.3 and 12.4 towers — from the Diamond 12 Series, and complete the system from our centre speakers range.
