EX2.5 MkII - Low Frequency Solution

The EX2.5MkII is a double 15" subwoofer and the ‘active’ brother of the ES2.6 passive bass module. It provides real depth and power where high bass output is required. The product uses the same low frequency amplifier found inside the EPAK2500/2500R and features in-built stereo crossovers, high pass outputs, and full overdrive protection. It also features a new speaker level output on an AP4 connector to drive one additional passive ES2.6 subwoofer from its own internal amplifier. (Not to be used with a passive ES2.5)
