Citronic CORVA-12S 12" 700W High-Power Passive Subwoofer 8 Ohm
The Citronic CORVA-12S is a 12" 700W RMS High-Power Passive Subwoofer delivering 127dB maximum SPL with a custom 4" voice coil sub driver, reinforced 18mm plywood enclosure and 35mm pole mount — built for larger venues and high-energy sound reinforcement environments demanding deep, powerful and dynamic low-end performance.
The Citronic CORVA-12S is a high-power passive subwoofer from the CORVA series, designed to deliver uncompromising low-frequency performance in demanding sound reinforcement applications. Loaded with a custom heavy-duty 12" sub driver featuring a large 4" voice coil and a 2.84kg (100oz) magnet assembly, the CORVA-12S provides the deep, powerful and dynamic bass that larger venues, high-energy events and professional sound systems demand. With 700W RMS and 1400W maximum power handling, 96dB sensitivity and 127dB maximum SPL, the CORVA-12S delivers the sound pressure levels required for large venues and high-energy sound environments when driven by high-powered professional amplification.
Custom High-Power Sub Driver
At the heart of the CORVA-12S is a 300mm (12") custom heavy-duty sub driver with a large 100mm (4") voice coil and a 2.84kg (100oz) magnet assembly — a specification that provides the high excursion capability, thermal headroom and sustained output necessary for demanding bass reinforcement at high power levels. The large magnet assembly ensures a strong, well-controlled motor system for precise, dynamic and deep bass reproduction across the 50Hz to 150Hz operating range, and the substantial voice coil diameter provides the power handling capacity needed to cope with the sustained high-power output of professional amplifiers in larger venue and event applications.
Rugged Construction & Practical Deployment
The CORVA-12S is housed in a reinforced 18mm plywood ported cabinet with a durable polyurea coating for long-term resistance to the demands of professional installation and event use. A powder-coated steel grille provides robust driver protection, and double carry handles on each side make practical transportation of this substantial 27kg cabinet as manageable as possible for a single operator or two-person installation crew. A 35mm pole mount socket on top of the cabinet allows compatible full-range loudspeakers — such as the CORVA-8 — to be mounted directly above the subwoofer for a compact, space-efficient PA stack. Two parallel Speakon input sockets provide secure speaker connectivity with easy daisy-chaining to additional cabinets.
