Hemp cone
The cone material is hemp, selected here for its tonal character.

Independent shopping perspective
The G12M-50 Hempback combines a hemp cone with a medium-weight ceramic magnet in a 12-inch guitar-speaker format. Its voice is defined by a forceful low end, balanced mids with a touch of crunch, and smooth upper frequencies. Celestion positions that more relaxed presentation alongside brighter-sounding amplifiers, where the speaker’s smoky, musical response can reshape the overall feel. The published 99dB sensitivity and 75Hz–5000Hz range give the configuration its key operating figures.
