The Marshall ST112 Studio JTM is a 65-watt, 1x12" semi-open speaker cabinet that brings vintage Marshall tone into a modern, compact design. Handbuilt in the UK, this cabinet features a premium finger-jointed plywood enclosure, elegant levant covering, gold piping, and the classic metal “coffin” logo, recalling the earliest days of Marshall amplification. Inside, the Celestion G12M-65 Creamback speaker delivers rich midrange, creamy highs, and punchy overdrive, perfect for blues, rock, or classic Marshall tones.

Designed to pair seamlessly with the Marshall ST20H Studio JTM amplifier head, the ST112 also excels with a wide variety of tube amps. Its semi-open back enhances the natural resonance and projection of the cabinet, giving you dynamic tone with plenty of presence. Lightweight and portable, the ST112 is ideal for stage, studio, or rehearsal settings where vintage sound meets modern build quality.
