About the LX521.4 Active Crossover Equalizer (ASP.4)
The Hairball Audio LX521.4 Active Crossover Equalizer (ASP.4) is an analog signal processor designed by Siegfried Linkwitz for the Linkwitz LX521.4 open-baffle loudspeaker system. It provides the active crossover and driver equalization needed to run the LX521.4 as a fully analog system, replacing the earlier miniDSP-based solution. Hairball Audio offers it as a fully assembled stereo unit and as PCB-based versions, with balanced or unbalanced input configurations.
