The Aguilar Eminence JDK12A (16-Ohm version) is a professional-grade, heavy-duty 12-inch bass guitar speaker driver custom-built for Aguilar Amplification's multi-driver cabinets. Manufactured in close collaboration with Eminence Speaker, this driver features a rugged cast aluminum frame and a 56 oz ferrite magnet assembly. It is precisely engineered to preserve the signature "Aguilar sound"—characterized by a warm, punchy low-end, incredibly articulate mid-range definition, and a smooth top-end finish that cuts through any live or studio mix. Because it carries a 16-ohm nominal impedance, this specific driver is primarily utilized in pairs or quads to achieve standard 8-ohm or 4-ohm system configurations, serving as the factory-correct component for legacy and modern multi-speaker setups like the Aguilar GS 212, DB 212, GS 412, and DB 412 enclosures.

Mechanically, the JDK12A is conservatively rated to handle 300 watts of continuous RMS power, relying on a heavy-duty copper voice coil wound on a high-temperature Kapton former to dissipate heat during intense touring use. The physical construction pairs a custom-blended paper cone with a treated cloth accordion surround, ensuring excellent linear travel and mechanical stability under high physical excursion. A protective paper dust cap covers the voice coil gap to keep out road dust and debris, while a standard multi-segment Rubitex front/rear gasket provides an airtight seal against the cabinet baffle plate. This meticulous layout guarantees highly efficient acoustic translation and excellent transient response, allowing bassists to push their amplifiers to the limit without experiencing premature low-frequency distortion or cone cry.
