JBL Summit Pumori: 3-Way, Floor-standing Reference Loudspeaker
The JBL Summit Pumori is a floor-standing reference loudspeaker built for the discerning music enthusiast. Summit Pumori is the flagship of the Summit Series for the 250mm woofer categorization.
Nicknamed “Everest’s Daughter”, rising to a height of 7.161m and situated just 8km west of Everest, Pumori is literally in the shadow of Everest. Mount Pumori is an attractive mountain that lies in upper Khumbu region of Nepal-Tibet. Climbers often use Mount Pumori to build confidence and gain technical skills before attempting to climb Everest.
Newly Designed Complement of Speaker Drivers:
Summit Pumori 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 Pumori are a 200mm cast-frame mid-bass driver and a 250mm 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.
Details:
JBL MultiCap™ Crossover:
Controlling how the signal is distributed to each of the drivers in Summit Pumori 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 Pumori to the ground are a set of custom designed JBL | IsoAcoustics® 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.
