By JBL’s own reckoning, the Summit Ama is the best standmounter it knows how to make. Let that sink in a little. JBL was founded back in 1946, and the decades of knowledge gained by making all sorts of speakers for use at home, in cinemas and concert venues, and for recording studios around the world, has led here. Few, if any, rival speaker manufacturers come close to this depth and breadth of experience
The Summit Ama is the smallest and only non-floorstanding option in JBL’s trio of Summit high-end speakers. All three are named after Himalayan mountains (the others are called the Summit Pumori and Summit Makalu). They all sit below the company’s well-established range-topping Everest DD67000 (£79,999 / $82,500) and K2 S9900 (£49,998 / $68,000) tower models in price and size.
Design & build
The Summit range’s technical highlight is undoubtedly the horn-loaded compression tweeter. JBL has decades of experience making such drivers, and the engineering in the D2815K unit used here in the Ama is impressive.
It uses dual 38mm annular Teonex diaphragms, two motor systems and is loaded by the company’s HDI (High Definition Imaging) horn.

The HDI horn is made of Sonoglass, a fibreglass-based material, and is carefully shaped to ensure that high frequencies disperse in a controlled way, both horizontally and vertically. The horn’s unusual profile also aims to reduce the distortions that are traditionally inherent in such designs.
Below the tweeter sits a 20cm triple-layer carbon fibre/cellulose hybrid composite mid/bass unit. This driver’s diaphragm sandwiches a closed-cell foam core between the carbon fibre/cellulose layers to achieve the balance of stiffness, low mass and internal damping that JBL’s engineers required.
The mid/bass’s motor system uses a ferrite magnet and has a cast aluminium chassis for rigidity. This driver is claimed to deliver high sound pressure levels with low distortion and good power handling. Its low-end output is tuned by a large, flared rear-facing port that sits just above the chunky set of biwire terminals on the back panel.
The Summit Ama’s two drivers are integrated by a carefully calibrated crossover network that swaps traditional large value capacitors for multiple smaller ones; a choice that reduces ESR ( internal resistance) and is claimed to result in lower distortion, increased power handling and better dynamics.
Physically, this JBL is a chunky design, standing almost 48cm tall and around 31cm wide. The cabinet depth is pretty substantial at 34cm, and when mounted on their dedicated supports, the speakers will certainly dominate in most typical small rooms in the UK.
Build quality is excellent. The Ama’s cabinets feel rock solid and nicely damped. They are substantial at just over 26kg each, so they need care in installation. There are two finish options, black or ebony veneer, both in high gloss. The overall effect may be a touch brutish for some tastes, but there is no denying the care taken in fit and finish.
Those aluminium stands are substantial affairs with twin pillars and isolating IsoAcoustics soft feet rather than the spikes we normally see. Some thought has been given to cable management to keep things tidy, which is something we wish more manufacturers would take seriously. The Summit Ama bolt onto the stand to keep things secure.
Compatibility
JBL quotes the Summit Ama’s sensitivity at 84dB/W/m and its nominal impedance as 4 ohms, which suggests that a high-quality amplifier with plenty of power is probably the way to go. Our experience reinforces this idea. We get great results with our 180-watt-per-channel Burmester 088/911 MkIII amplifier combination.
There is no point in spending so much on a pair of speakers if the partnering system is in any way compromised. Our sources are Naim’s ND555/555 PS DR music streamer and a Technics SL-1000R/Kiseki Purpleheart record player feeding the aforementioned Burmester pre/power or a PMC Cor high-end integrated. Cables are premium options from Chord Cables and Vertere Acoustics.
The Summit Ama prove relatively unfussy about positioning in our 3 x 7 x 5m (hwd) test room. They need a bit of space to breathe, so don’t be tempted to put them close to a wall or corner, as you’ll never really hear just how good they can sound.
After a bit of experimentation, we end up with them around 90cm into the room with just a little angling towards the listening position. It is worth taking some time to optimise the toe-in angle, as getting the best balance between solid stereo image focus and good soundstage width requires a little work.
Sound
Once properly set up, these speakers generate a huge sound that belies their relatively modest (by price standards) size. We are listening to 65daysofstatic’s Heat Death Infinity Splitter and are stunned by the wall of sound these JBLs produce. They sound bold and confident, generating a sense of solidity and authority that’s rare among high-end standmounters in our experience.
They sound earthy and physical, maybe lacking a touch of spaciousness some rivals produce, but compensating with a brawny, outgoing character that’s so easy to love. This muscular presentation is built on the foundations laid by the speaker’s weighty yet still pleasingly articulate bass performance. These standmounters delve deep and true at low frequencies, delivering a fullness and power in the bass that is unusual for a speaker of this size.
We find we’re listening much louder than usual. That’s because these JBLs retain their smoothness, refinement and composure even when pushed hard. Their highs may not be the sweetest we’ve heard, but there is no trace of unwanted tizz or edge, and the level of resolution is excellent.
Dynamics, both high and low level, are delivered with conviction. Not many alternatives are as good at resolving dynamic contrasts, and even fewer remain as interesting to listen to at low volumes. These JBL standmounts remain an entertaining proposition right down to whisper volumes, though it has to be said, they actively encourage the listener to turn the wick up.
All the work on optimising the horn shape works well. The Summit Ama’s sound remains surprisingly consistent as we move away from our main listening position. Their expansive imaging stays decently stable over an unusually wide listening area. We have no complaints about focus or the way these speakers layer the soundstage.
As we work through our most demanding test recordings (The Dark Knight OST by Hans Zimmer, Massive Attack’s Mezzanine and Stravinsky’s The Rite Of Spring), we can’t help but be impressed by the Summit Ama’s sonic unflappability. Their ability to retain control through the musical drama is excellent, as is the way they dig up so much information yet manage to organise it in a cohesive and musical way.
Tonally, we find they err on the side of richness; they sound pleasantly full-bodied and robust. This character trait gives voices and instruments an appealing palpability. We love the way they render instrumental textures and the skill with which they convey Nina Simone’s emotion in Sinnerman.
They are sure-footed rhythmically and convey musical momentum well. These speakers want you to have a good time with appropriate music, but feed them with Olafur Arnald’s Found Songs, and they are equally capable of getting introspective.
Verdict
The Summit Ama are one of the costliest standmounters we’ve ever reviewed, but their breadth of talents is hugely impressive. That they can rock should be no surprise to anyone familiar with the brand’s heritage, but it's their blend of insight, dynamic expression and finesse that marks them out as something special.
If you view your hi-fi as an analysis tool to dissect recording and production quality, there are alternatives which will serve you better. However, if you just want to have fun and get lost in the music, these JBL standmounters should be right at the top of your shopping list.
