I replaced the woofers in my Acoustic Research AR-16 that were 47 years old. The frequency curve was identical to the originals. Even the screw holes lined up perfect.

This works great for replacing the sub-woofer speaker in an Infinity BL1. The four mounting hole spacing is a little off, but its workable without drilling new mounting holes in a slightly different location. One of the speaker's female spade connectors is polarized (the minus I believe) by being a smaller width than is commonly used - that has to be replaced with a larger female spade connector.
