    Description

    PCB only!!! This is an 2.1 channel 2nd-order active crossover filter PCB for high quality speaker and amplifier projects. PCB is fully tested.
    The schematic includes a preamplifier (input buffer) stage, a summing stage for the subwoofer, and low-pass + high-pass stages for the crossover. Design uses 5 dual-channel 8 pin SOIC op-amps (OPA1678 or OPA1612 for example). All components are SMDs (size 3216 and 1206), except trimmer potentiometers and input power capacitors. For input and output wiring, you can 1) solder directly onto the 25um hole copper, 2) solder using small rivets (Mouser#:
    534-3384), or 3) use terminal blocks.
    Size: 135x105mm
    Will email a list of components upon payment. Will also help with filter crossover frequency calculations if needed (use Linkwitz-Riley filters with Sallen-Key topology).
