Summit Ama is JBL’s stand-mount entry in the residential Summit Series: a two-way system built around a horn-loaded compression tweeter and an 8-inch (200 mm) cast-frame woofer, with MultiCap™ crossover topology, bi-wire / bi-amp binding posts, and a mass-loaded dual-leg stand that ships with the pair. On JBL’s Summit Ama page, the line is unambiguous this is catalogue meant for listeners who already know why HDI horns and high current partners matter. The name Ama nods to Ama Dablam in the Himalayas; the Summit family also includes the larger Pumori and Makalu floor systems.
2-way stand-mount with D2815K 38 mm dual-diaphragm, dual-motor compression driver on a Sonoglass® HDI™ horn, plus JW200SC 200 mm HC4 triple-layer hybrid cone woofer (2.5-inch voice coil, ferrite motor, cast aluminium chassis, half-forward-roll surround). 1600 Hz crossover, MultiCap™ network, rear flared port. Published electricals: 84 dB sensitivity (2.83 V @ 1 m), 4 Ω nominal (3.1 Ω minimum near 239 Hz), 25–200 W RMS amplifier guidance, 107 dB max SPL. Finishes: high-gloss black with Summit platinum trim or high-gloss ebony veneer with Summit gold trim.

Drivers and horn
The high-frequency section uses JBL’s D2815K compression engine: dual 38 mm annular Teonex® diaphragms and dual-motor topology, mounted to a large-format Sonoglass® horn with HDI™ (High-Definition Imaging) shaping. JBL positions that horn as controlling directivity and lowering the distortion modes older constant-directivity shapes could smuggle into the treble.
The woofer is the JW200SC: an 8-inch unit with HC4 triple-layer hybrid carbon / cellulose sandwich (carbon-pulp skins around a closed-cell foam core), dual inverted spiders, 2.5-inch voice coil, ferrite motor, cast aluminium frame, and a half-forward-roll surround. The story is the usual JBL recipe — stiffness and damping without a cone so heavy it refuses to stop moving.
MultiCap crossover
JBL routes both drivers through a MultiCap™ network pitched as replacing a few large capacitors with many smaller ones to cut ESR and pass more transient current. The published electrical summary is a 1600 Hz crossover point with an acoustically symmetric third-order two-way slope (per Harman’s spec sheet wording). Internal wiring is called out as Ohno continuous-cast silver-plated oxygen-free copper.
Cabinet, stand, finishes
The enclosure is a curved-wall form with internal offset bracing and damping, built from sustainably sourced engineered wood and multi-component lining to chase standing waves. A single rear-flared bass port handles tuning.
JBL ships Summit Ama with a dual-leg steel-and-aluminium stand that is mass loaded and internally damped, bolted to the speaker for security. Feet are JBL | IsoAcoustics® isolators aimed at decoupling cabinet motion from the floor. Finish choices are high-gloss black with Summit platinum accents or high-gloss ebony veneer with Summit gold accents, plus carbon-fibre baffle trim called out on the spec sheet.
Published specifications
Figures below are taken from JBL’s Summit Ama specification sheet (metric and imperial columns as printed):
- Frequency response: 25 Hz–33 kHz (−10 dB, on-axis) / 34 Hz–25 kHz (−6 dB, on-axis)
- Sensitivity: 84 dB (2.83 V @ 1 m)

- Speaker with grille (H × W × D): 476.3 × 308.0 × 336.0 mm (18.6 ″ × 12.1 ″ × 13.2 ″)
- Speaker net weight: 26.3 kg (58 lb) each
- Stand (H × W × D): 650.6 × 412.2 × 412.2 mm (21.7 ″ × 16.2 ″ × 16.2 ″)
- Stand net weight: 20.1 kg (44.4 lb) each
- Shipping carton (including grille and stand): 660 × 982 × 537 mm; 57.2 kg (126.1 lb)
Amplifier and room
At 84 dB sensitivity and a four-ohm label with a sub-four-ohm minimum near 240 Hz, Summit Ama is not asking for a polite 25 W tube flea unless you listen quietly forever. JBL’s own power band runs to 200 W RMS suggestions translation: a serious integrated or separates stack that stays composed into two-ohm-ish reactive dips will behave better than a pretty faceplate with a thin power supply.
Depth is real: roughly 34 cm cabinet depth plus stand footprint near 41 cm square class. Leave boundary space for the rear port and expect toe-in experiments to matter for horn imaging.
Brochure and downloads
JBL hosts the public collateral on the product page: a Summit Series brochure (PDF), the Summit Ama specification sheet (PDF), and a Summit quick-start guide (PDF). Use those files for grille removal, stand hardware torque, and warranty region notes before you unbox 57 kg of freight alone.
FAQ
What is JBL Summit Ama?
Summit Ama is a Summit Series two-way stand-mount loudspeaker with a D2815K horn-loaded compression tweeter and an 8-inch HC4 woofer, MultiCap™ crossover, bi-wire terminals, and included IsoAcoustics®-based stands.
What finishes does Summit Ama offer?
JBL lists high-gloss black with Summit platinum accents and high-gloss ebony veneer with Summit gold accents.
How demanding is the load?
Published figures show 4 Ω nominal impedance and about 3.1 Ω minimum near 239 Hz, with 84 dB sensitivity at 2.83 V / 1 m. Choose amplification that is comfortable with low impedances and healthy current delivery.
Where can I buy Summit Ama and confirm price?
Use JBL’s Summit Ama page to reach regional configuration and authorised dealers. MSRP and promotion bundles change by territory; take a written quote from JBL or your dealer rather than relying on forum screenshots.
What else is in the Summit Series?
JBL positions Summit Pumori as a three-way 10-inch floor speaker and Summit Makalu as a three-way 12-inch floor speaker in the same family, for listeners who want more piston area than a stand-mount allows.
Note: Harman marks Features, specifications subject to change without notice on the PDF. If you are specifying a build around Summit Ama, re-pull the spec sheet the week of purchase.
