ESX DBX208BPQ Dual 8 Bandpass passive enclosure 800w. 2 x 20 cm (8) dual bandpass system. The new technology is easy to explain: the dual box DBX208BPQ is designed as a bandpass system in which the sound pressure exits a large port. The special thing about the design is the internal bass channel, which leads the sound either to the front or to the back. Depending on the application, the rear cover of the port, which is designed as a stable aluminum shield, can also be screwed onto the front opening. This alternative installation activates the rear channel opening and the entire sound pressure can be directed directly into the passenger compartment through the ski bag opening. The dual boxes can therefore develop their full potential, especially in convertibles or notchback vehicles. In addition to the conventional connection sockets, where the 2+2? Output can also be wired to a single 4 or even 1? Output, the box also has the innovative Quick Connect connection, which enables a plug+play connection to any amplifier via a 4-way Molex socket. This requires special Quick Connect connection cables, which are available in 4 different lengths. With Flex Port technology. 50 mm (2) voice coil. Subwoofer with handmade paper membrane. Embroidery Robust carpet cover. Quick Connect connection socket. Dimensions 78 x 29 x 39/29 cm.
