Mesa/Boogie 4x10 Powerhouse Bass Speaker Cabinet

Mesa Boogie has packed an array of innovative features into their exceptional range of premium-built PowerHouse Bass Cabinet Designs. This diverse series of cabinets offers an unsurpassed level of musical versatility and player convenience through the following 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-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! Player Control Network A proprietary new rear panel interface that provides unprecedented stylistic versatility and gig-friendly convenience includes: three-position switch for selecting your preferred crossover frequency, adjustable L-Pad for blending the right amount of high-frequency driver, resettable horn protection, and standard 1⁄4-inch and high-current SPEAKON locking connectors.Crossover Style Control & L-Pad Attenuator The Crossover switch provides three distinct tonal variations: Our time-proven, detail-enhancing sweet 5K (Normal) setting; the harmonic-friendly, accent-expanding snap of 4K (Sheen) and the modern, articulate cut of 3K (Bright). This feature, combined with the fine tuning adjustment potential of our premium L-Pad horn attenuator provides players with unrivaled stylistic high-frequency tweeter versatility and performance.Instant Reset Horn Protection A simple, one-touch reset switch provides convenient horn protection. No fuses, tools or digging inside the cabinet if your tweeter gets spiked. Just reset and play! SPEAKON & 1⁄4-Inch Connectors Convenient Inputs and Paralleled Outputs are provided for via "combination" connectors that feature both standard 1⁄4-inch AND locking SPEAKON high-current connections contained within the same connector.
