I have a 65 Fender Deluxe Amp, and I'm looking to get a new speaker. The speaker isn't blown, but I feel like I should get a new one, so that I can preserve the original. It just makes me nervous when I turn it up to 9 or 10. I'm pretty much lost when it comes to speakers, so I'd appreciate some suggestions. Should I go with another Jensen, or should I do something different? Thanks.
