Check the listing for details. Single Crossover PCB for the Argos DIY speaker design - PCB Board Kit. Condition: New. Listed at 12.00 USD. Custom printed circuit board designed for the crossover of the Argos DIY speaker design. Take the guesswork out of crossover assembly, these boards make the assembly process quick and straightforward. These boards measure 5.5" x 4.25" and features large solder pads and copper traces for great electrical connectivity Note - Photos of fully assembled crossovers are for reference only. Note - This listing has been revised from a pair of boards to single board in order to allow the purchase of these boards in an increment of 1 if odd numbers are required. Includes: 1x Crossover PCB for the Argos speaker design. 3x Terminal blocks which accept up to 12 gauge wire. 4x Snap in PCB standoffs. 4x Mounting screws (screw finish may vary). Requires: Crossover components for the Argos speaker design.
