Up for offer is this pair of fully functioning, Pioneer 4 way crossovers that were pulled from a Pioneer CS-J825Q speaker system.  There is one input and four outputs, a woofer (for 1 of the 8"), a midrange (for the other 8"), and 2 tweeter outputs.  Use them to replace yours, or they work great if you're building a 4 way woofer, midrange, and dual tweeter speaker system.  They are in mint condition with all of the connections present and labeling for ease of hook up and installation.  Pioneer made nice quality stuff back in the day, and these are sure not to disappoint.  Price is for both of them.
