C12D.
A high-gain twelve with a present bite and effectively bottomless headroom.
Fig. 01 — Frequency response · normalised, 1 watt
No scoop, no ice-pick — just extension.
The C12D's voice is the most balanced in the C-series — no P-family scoop, no piercing bite peak, just a gentle rise through the upper mids into an extended top. Bite reads chimey, edge reads articulate; the character is crisp rather than harsh. No honky bark, no ice-pick edge. A modern voicing in a Jensen badge — closer to a Celestion V30 than to its C-series siblings.
