Celestion Seventy 80 guitar speaker measurements



Last updated: April 4, 2016

This is a collection of my measurements about a Celestion Seventy 80 (or G12P-80) guitar speaker. For the close field measurements I've used a Laney TFX2 cabinet.
These speakers come stock in many guitar amps and compare to other generic guitar speakers they have a reasonable sound.
