Custom-built 300W bass speaker cabinet from Powerhouse series that offers an array of classic features and provides an exceptional level of musical versatility and player convenience. It is equipped with a specifically toned 15” Custom Eminence speaker. It features the 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. The innovative Tri-Port Design is a 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. The 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) fully ON, or any point in-between for personalized high-frequency versatility and performance. The cabinet’s enclosure is built by Mesa Master Craftsmen using the finest void-free, marine grade Baltic birch. Super strong rabbet and dado joinery is glued and nailed throughout the cab’s construction, including bracing and most importantly, the front speaker baffle. Grille is wrapped around a separate grille-board, not the baffle board. Grille material is made of strong twisted jute dipped in a special coating that filters top end for a sweeter response. The Track-Loc removable casters are included for easer transportation. Dimensions: 489 x 622 x 495 mm. Weight: 30.8 kg.
