SPL - Bassreflex 90l @ 53,4Hz (br area at least 450cm2)

Dual coil highed subwoofer with massive motor and massive input power. Unlike ordinary SPL woofers, this one has lower Qts and higher resonance frequency and sensitivity. Therefore it is also suitable to be used as a SQ woofer - not to produce some extremely deep bass, but have a nice fast and accurate output, good for music such as rock, metal, or any instrumental music. Huge 20kg motor ensures very high Bl even with coils in parallel. Coil itself is huge as well and has many features to improve cooling, which leads to extreme 2500W RMS and 7500W short-term maximum input power. Together with an amplifier which will provide enough power, it is capable of extraordinary things, but of course, it needs a lot of space in your car.
