ESX QXE10D2

The ESX QXE10D2 from the QUANTUM series stands out thanks to its compact design, high power handling, and rugged construction. With 600 watts RMS and a maximum power handling capacity of 1,200 watts, this 25 cm subwoofer is ideal for high-performance car audio systems that require powerful and precise bass reproduction.

The sturdy die-cast aluminum basket, the hand-formed paper cone, and the double-stitched foam surround ensure a durable construction. A powerful dual-magnet system with a total of 126 oz. (approx. 3.6 kg) is used to drive the driver. The generously sized 64 mm dual voice coil with a 36 mm winding height enables high power handling and large diaphragm excursions.

The ventilated pole piece and additional cooling of the drive system help dissipate heat during heavy use. The two 2-ohm voice coils allow for flexible wiring to either 1 ohm or 4 ohms, enabling the subwoofer to be adapted to different mono amplifiers.
