Eminence
Swamp Thang.
A hundred-and-fifty-watt twelve with a narrow, almost-piercing upper-mid peak, real bass extension under a hundred hertz, and headroom to outpace any guitar amp.
Fig. 01 - SPL response, on axis, 1m
Narrow upper-mid peak, almost piercing.
The Swamp Thang's voice is the darkest of the modern ceramics in this batch — a downward spectral tilt, no rising brightness, a forward narrow peak in the upper mids that reads cutting and almost piercing rather than vocal, and a real low end under a hundred hertz that the British speakers don't reach. The peak is the steepest rise of the cohort and sits at the top of the upper mids, just below ice-pick territory; the centre frequency is what saves it from spitting. No family scoop, no honky bark, no thick lower mids. The presentation is American-modern: weighted bottom, focused cutting upper mids, dark above the rolloff.
