Interesting on the 5150 and scooped mids. I recently bought a used 5150 412 cab. It needed some TLC (cosmetic), and after some cleaning and spraying the cab (in places) with truck bed liner, it looks great. Truck bed liner spray paint works pretty good on cabinet areas were the tolex is missing or torn. The torn parts I glue down first, then spray. Anyway, I use a Peavey JSX head and a Peavey XXX cab as my main amp. And I noticed when I plugged the 5150 cab into the JSX that the mids are way more reduced (scooped) compared to the XXX cab. Must be that "Metalhead" thing when Peavey designed the enclosure.
It was interesting the difference between the mids on these two cabs. I know both the XXX and 5150 use Sheffield speakers, not sure if they are the same.
