The Marshall Studio JTM Series ST112 speaker cabinet has a space-saving design and forms a dream-team in combination with Marshall's ST20C combo and ST20H amp head as well as various other, similarly-styled amplifiers with a maximum power capacity of 65W at 16 Ohms. This open-back cab is built in the same factory as the original sixties models and delivers the same trusty, Marshall-quality sounds, which it forces through a 12-inch Celestion GM-65 Creamback speaker to guarantee brutal bass, warm-and-crunchy mids and satisfyingly round trebles.
