ACT-Series Full-Range Speaker Systems
The ACT-Series full-range systems are capable of producing rich, clear, sound at extreme SPLs. The ACT amplifiers employ sophisticated circuitry including four stages of equalization, a built-in compressor/limiter and short circuit/over-current protection. The ACT-Series has an extra high current output stage, which sets it apart from the competition, allowing for uninterrupted extended play.
