This listing is for a single (1) ADS 501-0118 3-way crossover, removed from a Sat7 speaker I have parted out. I tested the speaker prior to disassembly & the crossover was in fine working condition.

 Please note: I have also seen the 501-0118 crossover used on the 750il speakers, but the boards look a bit different. They have push in connectors on the board where this one does not.
