Mesa Boogie packed an array of classic features into their custom-built
Traditional PowerHouse Bass Cabinets. These cabinets provide an exceptional
level of musical versatility and player convenience through the following
Traditional PowerHouse 4x10 Design Features include:
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-Port™ 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 old standard “shelf” designs or plastic port holes that blow all
your tone out of one large port hole!
Attenuator - Mesa's 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.
