The ELECTRA line was developed especially for those looking for incomparable bass. It has a frequency response of 5 to 500Hz (-3dBs). Due to this, the ELECTRA will only play Subwoofers , Bass and part of the mid frequencies. The BASS BOOST @ 45Hz feature is a differentiator, further reinforcing the bass of your system. Designed on a 100% aluminum chassis , it works with a power of 3000 WRMS with 1 input channel for connection and an impedance of 2 Ohms. It has very low harmonic distortion (less than 1%) and Clipping indicator, forced ventilation and short circuit protection. Furthermore, it has a bold and clean design, matching any sound system.
