Welcome Reverb community.
You are considering an original working single Infinity Reference Three crossover network. This is complete with baffle part as shown.
This, and many other parts in our inventory have been salvaged from their main components and made available in our committed effort in placing them back into the audio community for anyone who may need, or want them for replacement or project purposes. Many parts are from components long discontinued and unavailable in after market form...
JSW does not provide instructions or assistance on replacing parts, and recommend buyers seek assistance from a qualified technician. Before purchasing a replacement part, it is very important you run as many tests possible to single out the source of your issue: Bad connections/amp/receiver/crossovers left unchecked/fixed, will keep burning out your parts.
ALL DRIVER PARTS SALES ARE FINAL.
