RDL ST-CX2S Subwoofer Crossover Filter
Overview
The ST-CX2S is a subwoofer signal equalizer in the STICK-ON series of products from RDL. The ST-CX2S offers flexibility in equalization adjustment, with the exceptional performance of RDL.
The ST-CX2S features two separate, isolated balanced bridging inputs which may each be wired balanced or unbalanced.
