ESX SL300A

The ESX SIGNUM SL300A is an exceptionally compact active subwoofer system designed specifically for space-saving installation in the spare tire well. Starting with 15-inch rims, the system can be integrated into many vehicles without taking up valuable trunk space.

The rugged enclosure is made of shatter-resistant ABS plastic with good acoustic damping properties. As a result, the SL300A has a low total weight of just 2.8 kg. Inside, a specially developed 13 cm subwoofer with a powerful magnetic drive and a long-wound 38 mm voice coil is at work. Together with the tuned bass-reflex port, this design enables surprisingly powerful and deep bass reproduction despite its compact dimensions.

A standout feature is the built-in 3-channel Class A/B amplifier. In addition to the subwoofer with 100 watts RMS, there are two additional amplifier channels, each delivering 35 watts RMS. These can be used, for example, to power existing factory-installed speakers, thereby enhancing the overall sound system.

Thanks to its RCA and high-level inputs, as well as its automatic power-on function, the ESX SL300A can be integrated into a wide range of factory-installed audio systems. The included wired remote control allows for convenient adjustment of key subwoofer settings.
