2 x 20 cm (8) dual active bandpass system. The new technology is easy to explain: the active speaker DBX208BPA 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 directs 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 sturdy 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 speakers can therefore develop their full potential, especially in convertibles or notchback vehicles. The active speaker is particularly impressive in convertibles with a small trunk, as no additional space is required. Module also offers all the modern features that are required in many vehicles today. In addition to start/stop, the variable EPS Pro is also on board to outsmart the error diagnosis of various vehicles.
