Speaker - Jensen® Vintage Ceramic, 15", C15N, 50W
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.
- Lows: Fat
- Mids: Aggressive
- Highs: Bright
- Overdrive: Smooth

I have a vintage altec lancing that is like an icepick, will this speaker mellow the tone? I am running a vibroverb clone. Thanks! Bryan Schang

Hello,
Without having hands on experience with the particular Altec Lansing speaker, we advise locating a frequency chart for your speaker and comparing it to the one above for the C15N. In our experience, this is a fairly bright speaker, so it may not be the ideal choice.
