***PLEASE DO NOT POST IN THIS THREAD***WORK IN PROGRESS***
DISCLAIMER: Here are parts lists for the most commonly modified Polk speakers. Treat these lists as a guide, not as scripture as there were many transitional and variant Polk speakers sold. The list is for a single speaker; double the parts if you are modifying both speakers. Also, only capacitor, resistor, and inductor parts are listed. Polyswitches and bypass capacitors have been omitted due to the fact that they are usually not replaced when modifying or upgraded most classic Polk speakers; even though inductors usually are as well. Please double check all parts lists and schematics against your actual speakers before you order parts or start modifications.
If you have any questions or comments, or would like to request a parts list be added, email me at firstname.lastname@example.org.
