What is your overall opinion of this product?
I have two of these that came stock in my Fender Custom Vibrolux Reverb (CVR) Tube Amp and they are one of the best all time speakers ever. Clear and bright with plenty of warmth and punch. Made of expensive materials, including cobalt in the magnet, hence the high price. Aluminum-Nickel-Cobalt magnets, or ALNICO, are the stuff of legends.
These were the main stay speakers of the early Fender Super Reverbs, and definitely a part of that amp's great vintage sound and legend all the way back to the 1960s. Makes perfect sense why you find them in a Fender Pro Tube Series amp like the CVR.
