The JBL Summit K2 is a floor-standing reference loudspeaker built for the discerning music enthusiast. Summit K2 is the flagship of the Summit Series for the 15-inch (380mm) woofer category.

K2 (k-too) The world’s 2nd highest mountain at 8,611m (28,251’). One of the most dangerous and famous mountains. Unlike other mountains that were given a name, K2 has kept its survey notation name from the first survey of the Karakoram range back in the mid-1800’s.

Newly Designed Complement of Speaker Drivers
Summit K2 features a newly engineered mid/high-frequency system that combines the output of three patented JBL D2815 1.5-inch (38mm) dual-diaphragm, dual-motor compression drivers with a custom-designed, patent-pending 3-into-1 expansion manifold, precisely mated to a custom large-format Sonoglass® High-Definition Imaging (HDI™) horn. This mid/high-frequency system delivers exceptional detail and clarity across a wide frequency bandwidth, extending from the 1,080Hz crossover point of the dynamic drivers to beyond the reaches of human hearing.

Anchoring the sound foundation of Summit K2 is a 10-inch (250mm) cast-frame Differential Drive mid-bass driver and a 15-inch (380mm) cast-frame Differential Drive woofer. Both dynamic drivers employ JBL’s triple-layer Hybrid Carbon Cellulose Composite Cone (HC4), constructed from a proprietary formula of carbon-fiber and pure-pulp front and rear skins sandwiching a closed-cell foam core. This advanced cone architecture provides optimal stiffness, overall mass, and structural integrity required for high output, low distortion, and exceptional power handling.

JBL MultiCap™ Crossover
Controlling signal distribution within Summit K2 is an advanced MultiCap™ crossover network that supports single-wire, bi-amp/bi-wire, and tri-amp/tri-wire connectivity.

By replacing traditional large capacitors with a greater number of smaller capacitors, this network reduces ESR (Electro-Static Resistance) and minimizes energy loss due to mechanical movement. The result is greater signal transfer to the drivers, increased power handling, enhanced dynamic expression, ultra-low distortion, and exceptional overall clarity.

Crafted from Luxurious Materials
All drivers and crossover components are housed within a meticulously engineered and beautifully finished enclosure featuring internally offset, multi-braced, and damped pre-stressed pressed curved-wall construction designed to minimize internal standing waves. Summit K2 cabinetry is offered in a choice of high-gloss painted black with Summit platinum accents or high-gloss ebony wood veneer with Summit gold accents.

Grounding Summit K2 is a set of 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.
