ESX QXB8A – 20 cm (8") Active Subwoofer with Integrated Amplifier
Full description
The ESX QXB8A is an active subwoofer designed for lovers of deep and powerful bass , without the need for an external amplifier. Thanks to its integrated Class D amplifier (Power4 Active Module) , it offers up to 400W RMS and 800W Max , guaranteeing high efficiency (84%) while consuming little energy.
With its compact design , this subwoofer is ideal for discreet installations in the trunk or under a seat. It can be used in "down-firing" mode (diffusion downwards) thanks to the supplied brackets , thus improving the sound reproduction.
