Mesa Boogie Powerhouse series 4x10 bass cabinet 2010's. Super clean black Tolex finish with a metal grille. This unit is equipped with the original four 10-inch speakers and a high-frequency horn. The back panel has a crossover switch, an attenuator for the horn, and multiple input/output jacks. It is mounted on original heavy-duty casters for mobility. I only used it during summer tours at a quiet level and it had a custom case. Was very babied so it's in excellent shape. I just have way too many bass cabinets. Thinning..
