Ciare SPL CSW70 EVO Dual 2Ω Competition Subwoofers — 12″ / 15″

Ciare SPL CSW70 EVO Competition SubwoofersSale unit: Sold individually — one subwoofer.The CSW70 EVO family is Ciare’s high-excursion dual-2-ohm competition subwoofer platform in 12- and 15-inch sizes. Both use a 3-inch voice coil and the same published high-power program rating, but the larger 15 adds cone area and requires more enclosure space.Choose the Size12-Inch — CSW7012EVOThe 12-inch version is the easier package when baffle area and enclosure volume matter. Ciare publishes 91.5 dB sensitivity, a 30–200 Hz frequency range and 23 mm Xmax for this model.15-Inch — CSW7015EVOThe 15-inch version increases cone area for builds that can support the larger enclosure. Ciare publishes 92.6 dB sensitivity, a 25–200 Hz frequency range and the same 23 mm Xmax.Power Rating — Use the Technical TableCiare’s current technical specification tables list both EVO models as dual 2 ohm with a 3-inch voice coil, 700 + 700 watts nominal and 7000 watts program. Some marketing copy for the 12-inch model uses a different power figure, so this listing follows the manufacturer’s technical table rather than mixing the conflicting numbers.Installation Notes Dual 2-ohm coils: calculate final system impedance before selecting the amplifier. These are high-excursion drivers; verify motor, surround and rear clearance in the enclosure. The 12- and 15-inch models require different box designs. Do not scale one enclosure by guesswork. Competition-level output requires appropriate charging, battery capacity, conductor size, fusing and measured gain setup. Included: one selected Ciare SPL CSW70 EVO subwoofer. Enclosure, grille, wiring and mounting hardware are not included unless specifically stated elsewhere.
