Seen some posting here that said these were brittle and harsh sounding. Just put one in my Tweed Proluxe (30 watt Deluxe). Sounds incredible! Just thought I'd try one out with concenrs about weight. I'm not getting any younger. I was really suprised witht the Tone of this speaker considering I've had Eminence, two Webers, Mojo V30, Greenback, Jenson, and a couple more I cant even remember in it. This is the speaker for this amp. I really liked the Mojo but it died. I really love the lightness. I've got two Century Vintages on the way also. Gonna give em a try. Th EQ Curve of this speaker ended up being perfect for this amp. It can be a little bass heavey. The resonanace starting at 80 wrather than 75 hz. One happy camper. Dont get the harshness argument.
