Mesa Boogie Traditional Powerhouse TT-4 115 Bass Amplifier Cabinet

Mesa Boogie

We've packed an array of classic features into our custom-built Traditional PowerHouse® Bass Cabinets. These cabinets provide an exceptional level of musical versatility and player convenience through the following features:

1x15 Design Features

Aviation Style Bracing

A radical bracing concept borrowed from the aircraft industry. All structural reinforcement is dado-joined and sculpted to form an extremely strong skeleton that reduces weight, increases rigidity and improves structural integrity.

Tri-Ported Design

An innovative front-facing, multi-vent porting system that uses individually tuned triangular ports to enhance each part of the bass spectrum. Each port is part of the structure and reinforcement of the cab and speaker baffle in addition to its porting function. This goes way beyond the standard “shelf” designs or plastic port holes that blow all your tone out of one large port hole!


Our premium L-Pad high-frequency horn attenuator provides players with the ability to fully adjust the level of the tweeter, ranging from fully OFF, (bypassed) ON, or any point in-between for personalized high-frequency versatility and performance.
