JBL Summit Makalu

The Summit Makalu, a floorstanding loudspeaker built for the discerning music enthusiast. It features a newly designed complement of drivers starting with JBL’s D2830K 3-inch (75mm) dual-diaphragm, dual-motor compression driver mated to a large format Sonoglass High-Definition Imaging (HDI) horn. Anchoring the sound foundation of Summit Makalu are an 8-inch (200mm) cast-frame mid-bass driver and a 12-inch (300mm) cast-frame woofer. Both drivers utilize 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 Makalu 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 (Electro-Static 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. 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.
