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.
