The Summit Ama, a stand-mount loudspeaker built for the discerning music enthusiast. It features a newly designed complement of drivers starting with JBL's 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 an 8-inch (200mm) 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.
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 (Equivalent SeriesResistance) 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.
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. Grounding Summit Ama is a matching dual- leg, internally damped, steel and aluminum floor pedestal fitted with custom-designed JBL | IsoAcoustics® isolation feet that counteract the vibrational forces generated by the drivers, effectively decoupling the loudspeaker from the supporting surface. This isolation contributes to tighter bass performance, a more expansive soundstage, and imaging defined by greater clarity and spatial precision.
