Eminence.
Eminence supplies Peavey, Mesa/Boogie, Carvin and often the Fender reissue line. If an amp left a North American factory in the last twenty years, an Eminence speaker was very likely bolted into the back of it — usually without Eminence’s name on the magnet. The business is half OEM, half own-brand: licensed vintage clones (their Greenback and Blue derivatives) and the Patriot line — Governor, Cannabis Rex, Swamp Thang, The Wizard, Man o’ War, Red White & Blues — each carved into a named voicing.
Where Celestion’s catalogue orbits a small number of hero speakers, Eminence spreads wider. The Patriot range alone runs from the clean-headroom Cannabis Rex through the palm-mute-ready Swamp Thang to the Alessandro-voiced alnico signatures. If you need a specific voice at a specific power budget, Eminence usually has the one.
