This would be a nice change if you are looking for something different. These speakers will be voiced with more of an American flavor as compared to the typical British style of speakers. For more information please see the Jensen Tone Generator: https://www.jensentone.com/tone_generator

Stefan - May 16th, 2018

This is my favourite speaker. It has such a sweet sound and it's never too boomy. I'd highly recommend it for all styles of music. It's the stock speaker in my deluxe reverb and I had to get another one so I could have that familiar sound in a different cab. Amplified parts shipped it out very fast!

This speaker unbeknownst to me is what Fender now puts into their reissue Deluxe Reverbs. It replaces an aging Oxford in my own DRRI and the sonic improvement after the install was astounding. Deeper lows without flapping, tighter midrange and smoother highs, totally bringing the character of this venerable amp in line with my expectations.
