The Blackface era sibling of the P15N is a powerful, open sounding speaker with a cutting presence on the full range of frequencies. The C15N is very efficient and delivers dynamic, high-headroom and punchy tone from bass to trebles. It is the first-choice speaker for many pedal steel and blues players.  It is very commonly found in Pro® and Vibrolux® amps in the ‘60s and is used in the low frequency drum of the Leslie® 122 and 147 amplifiers.

Guitarist Description
Tight low-end and clear, bright highs. Responds to overdrive distortion with a gritty edge.

Yes the Jensen 15" guitar speaker works great in my Fender Deluxe amp. I had to custom fit it but it sounds great.
