Are JBL’s range-topping Summit speakers worth $160,000? I've had an exclusive listen to find out
The Summit of loudspeaker performance?
There have been quite a few candidates vying for the ‘most exciting pair of hi-fi speakers making their grand public debut’ award at this year’s High End Vienna showcase.
Bowers & Wilkins treating the world to the fifth iteration of its 800 Series Diamond range is no small thing, whereas Ruark’s resurrection of its Talisman-R floorstanders is similarly big news but at a significantly lower price point.
Then there’s JBL. The US giant has added twin peaks (sigh) to its five-strong Summit range, with the range-topping Everest and K2 loudspeakers joining the established Summit Makalu, Pumori, and five-star Ama models.
If you want to know what the K2 and Everest are all about, one word springs to mind: big. Both stretch the bounds of both physical size and required cost, with the mighty K2 costing a mere $100,000 and the colossal Everest pushing the needle at a whopping $160,000 per pair.
Big speakers at big prices from one of the biggest names in audio. You know where this is headed – we had to go and give them a listen.
We have already heard the baby of JBL’s Summit range, the effervescent and richly talented Summit Ama standmounts, so as the iPad is unleashed and the test tunes queued up, we’re quietly hoping for those enviable qualities of punch and dynamism to have translated all the way up to the snowy peak of JBL’s mountain-themed roster.
With Mark Levinson’s 626 preamplifier and 631 monoblock stereo amp in tow, it’s time to call in the sherpas and start our trek up that most famous of famous peaks.

As Pete Belsasco’s Deeper blasts out across our reasonably spacious demonstration room, it’s clear that much of the punch and power, not to mention the poise and balance of the five-star Ama, does seem to have translated to these rather more bank-busting pair of Summit range-toppers.
Harman’s engineers quite candidly confess that they would have liked a narrower space in which to work in order to stop sound from dissipating before it reached each side wall, so our usual disclaimer about less-than-ideal test conditions must once again apply here. Show us an ideal demonstration room at a hi-fi show and we’ll show you a talking unicorn.
Deeper is a smooth, jazzy number designed simply to get things started with something relatively undemanding; a move over to Fink’s Trouble’s What You Are In grants a better showcase of what well over $100,000 can get you.
These are big, bold speakers, yet we do sense an admirable feeling of intimacy and closeness to Fink’s acoustic performance as he croons away during a live recording of his aforementioned sampler. What impresses us as we listen more and more is how the Everest seem to switch gears, moving from small-scale sincerity to more dramatic and demanding fare without painting everything with the same broad brush.
JBL is keen to show the depths to which the Everest are capable of sinking, so we turn to the Sound of Silence performed courtesy of Geoff Castellucci’s deep, rumbling baritone.
Thanks in part to those whopping cabinets and JBL’s three-in-one ‘Phase Coherent Manifold’ – wherein a trio of compression drivers are aligned in a balanced symmetrical configuration and mounted to an HDI geometry horn – Castellucci’s ultra-deep pipes plunge to below the basement depths, yet we sense that the speakers’ control and articulation at these extreme low reaches is enough to keep everything sounding remarkably intact.
The Everest come across as powerful and weighty, too, as you might expect from loudspeakers of this size and price. Our demo team want us to “have some fun”, and so Adriatique and Delhia de France’s pulsating rave tune The Future is Unknown kicks things up a gear – bass drum thumps land with proper wallop, vocals feel precise and well spotlighted, while assorted musical decorations are rarely lost amidst the clamour.
Midrange tones don’t appear to be put in the shade by any overpowering bass, either. If anything, those all-important middle frequencies punch through with remarkable gusto, an enthusiasm which sometimes threatens to tip over into hardness or over-eagerness.
Take that minor reservation with a very large heap of salt, though – these are very large speakers playing very loudly in a modest, poorly conditioned space, and such quirks are almost inevitable. Our overall impression is of a pair of speakers that blend fun and muscularity with considerable nuance and restraint, resulting in a demo that, while short, appeals as much to the heart as it does to the head.
The Summit Everest are JBL’s range-toppers in terms of both price and, from the little that we have heard, performance. As we are told during our sampler, the brand’s engineers were told: “don’t worry about the cost, don’t worry about the components, just make them sound as good as you can.”
Such money-no-object speakers don’t come around often, and while we imagine it can be tempting for designers and engineers to throw their cash around without the same care and attention reserved for more modestly priced models, we rarely had a sense of the Everest sounding like a throwaway indulgence. Proper sound is what we expected and, from what we hear, proper sound is what they deliver.
Are they worth their Olympian price tag? We’d need a lot more testing time to find that out.
We wonder if JBL gives out free samples…
