Product Description
The ESX QXB6A belongs to the QUANTUM QXB series, which incorporates the latest technologies to offer a high-performance active subwoofer .

This active subwoofer does not require an external amplifier , simplifying installation while ensuring powerful and precise bass. It has several settings, including an adjustable low-pass filter (40-120 Hz), a phase corrector (0°/180°), a Bass Boost (+6 dB at 45 Hz) and a high-level input with Auto Turn-On function.
At just 16cm tall , the QXB6A can be installed under a seat, in a double trunk floor or behind a seat. It also comes with a wired remote control for adjusting the bass from the driver's seat, as well as optional feet for downfire installation , ideal for trunks.
