ESX Quantum Q-208A - 20cm under seat subwoofer active

Q208A

The legendary QUANTUM Q202A active under-seat subwoofer has a worthy successor in the new and improved Q208A. Its compact dimensions remain unchanged, ensuring that it continues to fit under many vehicle seats. With an impressive 150 watts RMS, the integrated Class A/B amplifier delivers a whopping 50% more power than its predecessor. Important features such as the automatic switch-on function and high-level input have been retained to enable integration into modern factory systems, even if there is no remote control line and no preamplifier signal via RCA. A new feature is the passive membranes installed on both sides, which are protected by robust metal covers and give the housing a distinctive look. This is rounded off by an ESX logo discreetly stamped into the protective grille of the woofer, which provides additional stability. Thanks to extensive features such as phase control and active low-pass crossover, the powerful bass sound can be optimally adapted to the vehicle's acoustics. Of course, the Q208A also has a wired remote control for adjusting the bass level. Although the height of the enclosure is very low, there is still room for two oval passive membranes on both sides. This means that the actively driven subwoofer is supported by passive resonance, especially at low frequencies, and a richer bass foundation is generated through greater air displacement.
