I've been researching the Big Ben 15" speaker and it seems to get a lot of positive reviews in Tweed amps and Marshalls. Haven't seen much about it in blackface Fenders. Anybody here have any experience with the Big Ben in a blackface Fender amp or similar? As a reference, I think the latest version of the Eminence Red White & Blues is an amazing blackface 12" speaker. Big fan of the Weber F150's too. I'm looking for a similar tonal response and efficiency in a 15". The Weber California I have now isn't cutting it - too quiet and flat.
