ESX SL300A - Ultra-compact active subwoofer spare wheel
Full description:
The ESX SL300A is the perfect solution for small and city cars looking to add deep bass without sacrificing trunk space. Its innovative design allows it to be installed directly in the spare wheel well (from 15 inches) .
This ultra-lightweight enclosure ( only 2.8 kg ) is made of robust ABS , a material offering excellent sound insulation . Its 13 cm (5.25”) subwoofer with a 38 mm long voice coil and its integrated 100W RMS Class A/B amplifier (200W max) deliver powerful and precise bass.
The SL300A doesn't stop at bass : it has two additional channels (2 x 35W RMS / 50W max) allowing you to amplify satellite speakers to further improve the sound reproduction. It is therefore ideal for boosting the original audio system without complex installation.
Its integration is simple thanks to its high-level inputs (with automatic ignition) and RCA via Molex connector , and it offers advanced settings such as a low-pass filter (50-150 Hz), a subsonic (25 Hz fixed), a phase adjustment (0°/180°) and a wired remote control to adjust the bass volume easily.
