ESX QXB8 - 8" Subwoofer Enclosure



The vented QUANTUM QXB enclosures feature a very compact design . With an impedance of 2+2 Ω each, the subwoofer can also be operated in 4 Ω or even in 1 Ω in order to get the maximum out of the amplifier. Thanks to the large voice coils (50 mm at the QXB6 and 64 mm at the QXB8 and the new model QXB10, these subwoofers are designed for a dynamic performance and can be powered by even more powerful amps. Thanks to the flat design, the new QXB enclosures find the right place in almost every vehicle. With a height of only 16 cm, the QXB6 box can even be placed in a double floor of the trunk, or for example behind the seat. The included protection grilles protect the woofers optimally in all models. For QXB6 and QXB8, optional standing feet are included, allowing the speakers to be placed on the belly in the trunk. This means that the upper side can be used as a shelf in the trunk, while the subwoofer "fires" downwards.
