Description
When your MB150S or MB150E combo is holding its own but the room needs more push, the 112-MBX gives you extra low-end muscle without turning your gig bag into a workout. This is Gallien-Krueger’s answer for players who want a bigger footprint of sound but still want to carry the whole rig in one trip to the car.
Weighing in at just 12 lbs, the 112-MBX pairs a sealed aluminum enclosure with a steel grille and the same 100W speaker found in the combo amps it’s built to match. That shared DNA means the tone stays consistent — you’re simply adding more air displacement and stage volume, not changing your sound. Bassists running small combos for club gigs, jams, or pit work will feel the difference the moment the extension cab kicks in.
For players who need to get the cab up off the floor and pointed at ears instead of knees, the optional MB Mic Kit lets you mount the 112-MBX on a standard mic stand for better projection and coverage.
- 100W RMS at 8 ohms
- 1×12″ Paragon ceramic driver
- Aluminum enclosure — lightweight and road-tough
- Steel grille for stage protection
- 1-year speaker warranty, 2-year electronics warranty from Gallien-Krueger
Built to extend, not replace — the 112-MBX keeps your micro bass rig gig-ready while giving it real headroom.
