If you want to beef up your Blackstar Unity Bass Series combo, then you need a Unity U250ACT powered cabinet. You’ll experience classic low-end muscle via a custom-designed Eminence Opus speaker, while an independent volume control makes balancing your levels a breeze. This flexible cab’s XLR combo input allows you to use it with external preamps, while a passive 1⁄4″ input lets it function as a standard extension cabinet. And if you really want to build a monster rig, use the U250ACT’s XLR Thru to chain together multiple cabinets.
