JBL Summit Ama

2-Way, 8-inch (200mm) Stand-mount Loudspeaker The JBL Summit Ama is a stand-mount reference loudspeaker built for the discerning music enthusiast. Summit Ama is the flagship of the Summit Series for the 8-inch (200mm) woofer categorization. Ama (a-ma) From the full name Ama Dablam, meaning ‘Mother’s Necklace’ and reaching a height of 6,812m (22,349’). Ama dominates the eastern skyline from Everest Base Camp and has been called the “Matterhorn of the Himalayas” due to its impressive iconic shape. Newly Designed Complement of Speaker Drivers Summit Ama features JBL's patented D2815K 1.5-inch (38mm) dual-diaphragm, dual-motor compression driver mated to a large format Sonoglass® High-Definition Imaging (HDI™) horn. Anchoring the sound foundation of Summit Ama is a 8-inch (200mm) cast-frame cast-frame woofer utilizing a triple-layer Hybrid Carbon Cellulose Composite Cone (HC4), a design made from a proprietary formula of carbon-fiber and pure-pulp front and rear surfaces, sandwiched with an internal core of closed-cell foam. This hybrid cone design provides the proper stiffness, overall mass, and structure to deliver high-output, low distortion, and high-power handling. JBL MultiCap™ Crossover Controlling how the signal is distributed to each of the drivers in Summit Ama is a MultiCap™ crossover network with single-wire and bi-amp/bi-wire connectivity. By replacing traditional large capacitors with an increased number of smaller capacitors, this design results in lower ESR (Electrostatic Resistance) and less energy lost in mechanical movement. All of which results in greater signal throughput to the drivers, increased power handling, enhanced dynamics, ultra-low distortion, and exceptional clarity. Crafted from Luxurious Materials All drivers and crossover components are housed in a beautifully engineered cabinet featuring internally offset multi-braced and damped curved-wall construction to minimize internal cabinet standing waves. Enclosures are offered in a choice of a high-gloss painted black finish with Summit platinum accents or high-gloss ebony wood veneer finish with Summit gold accents. Anchoring Summit Ama's included matching mass-loaded damped floorstand to the ground are a set of custom designed JBL | IsoAcoustic® isolation feet that resist the vibrational forces caused by a speaker’s drivers effectively decoupling the loudspeaker from the surface on which it resides. This isolation delivers tighter bass, an improved soundstage, and imaging with greater clarity and sense of space.
