Up for your consideration: a single Pioneer two-way speaker crossover, from a Model S-P5000 speaker cabinet. Tested and working great, fully functional.  Should be applicable to other models--check your intended use.

Markings: SWN1204-C.

 
Will be packed carefully and protected with my usual assortment of packing material.

Great for restoration/replacement/DIY/spare. I combine shipping whenever safely possible.

 

Footnote on shipping:

I usually use USPS Priority Mail and FEDEX.  Sometimes mail delivery is slow, no matter what carrier I use.  This is a hobby for me, not a high-powered business; however, rest assured I use real packing materials to make sure your item arrives undamaged.  You get the same high quality shipping treatment from me if you buy an inexpensive item or rare, high value components.
