This is a far way off, but I'm thinking about speakers already for the 5E3 chassis I'll be putting together. I'm going to go with a Weber Jensen clone. I have an 18w Brit 2x10, as I want this to be a solidly American sounding.
My contenders are the standard 12A125 (P12Q) and the 12A150W (P12NT). The 12A125 is the popular snadby, but 12A150W is calling to me. It's bigger magnet should make it a bit louder and more touch responsive. It's cone has fewer ribs making it a tad less smooth, and its description almost makes it sound like an American speaker with a touch of Brit-like upper mid karrang: "Bright, moderately crunchy breakup, midrange punch, twangy, aggressive, loud, compresses at higher volumes" with "Country Tele twang" and "lots of midrange punch and upper midrange bite."
Has anyone had experience with the big 40oz magnet in a 5E3 circuit? Is it too bassy and will it be overly woofy? How about any other suggestions for a bright American sounding speaker?
