EX2.5 MkII - Low Frequency Solution

EX2.5 MkII - Low Frequency Solution
  • Double 15” subwoofer and the ‘active’ brother of the ES2.6 passive bass module
  • Provides depth and power that belies its size 
  • 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 a EP4 connector to drive one additional passive ES2.6 subwoofer from its own internal amplifier. (Not to be used with a passive ES2.5)
