Hi-Fi News has reviewed the JBL Summit Makalu, so I put it on file. The JBL Summit Makalu is the 64th JBL product on our books, the 17th JBL floorstander, and the first from the Summit Series. It costs 44,995 dollars a pair.

Then I ran it through our own amplifier matcher and got a number I did not expect from JBL.
Quick facts
- 44,995 dollars a pair. That is JBL's launch price from May 2025. Definitive Audio, the US launch dealer, asks 44,999.90.
- 88 dB sensitivity, 4 ohms nominal, 3.5 ohms minimum at 79 Hz. Both figures are JBL's own, quoted at 2.83 V and 1 m.
- Our matcher asks for at least 160 watts a channel. For the same job it asks 25 watts of the K2 S9900 and 13 watts of the Everest DD67000.
- It is the least sensitive JBL floorstander we hold, level with the 1,198 dollar Studio 680, and the harder load of the two.
- The Summit Series is five models now. Ama, Pumori, Makalu, and new versions of the K2 and the Everest that are not shipping yet.
What it asks of an amplifier
Our matcher works out the power a speaker needs from its sensitivity and its impedance, then ranks the amplifiers we hold against it. I asked all three JBL flagships the same question: a large room, loud listening, 102 dB peaks at four metres.
Minimum amplifier power for three JBL flagships, from the Speaker Decision amplifier matcher
The Makalu needs about twelve times the power of the Everest. You can check that without the tool. Sensitivity is quoted at 2.83 V, which is one watt into 8 ohms but two watts into 4 ohms. So the Everest DD67000 gets 96 dB from a watt and the Makalu gets 85 dB from a watt. Eleven decibels is a factor of about twelve in power, and the tool says 13 watts against 160. The arithmetic and the tool agree.
This is not a fault. It is a design choice, and 160 watts is not a hard amplifier to buy. Our matcher's own sensible pick was the Mark Levinson No.585.5, 200 watts into 8 ohms and rated down to 4. But it is worth knowing before you shortlist a valve amplifier, because JBL is the brand people buy when they want to use one.
One oddity in JBL's own sheet. The Makalu is rated for 25 to 300 watts. The K2 S9900, which needs a sixth of the power, is rated for 500. Recommended power ranges describe what a driver can survive, not what it needs to play loudly, and those two things point in opposite directions here.
The least sensitive big JBL we hold
We hold 17 JBL floorstanding speakers with a published sensitivity. Here is the top of the range, sorted by price.
| Speaker | Price a pair | Sensitivity | Impedance | Announced |
|---|
| JBL Everest DD67000 | 75,000 dollars | 96 dB | 8 ohm | 2013 |
| JBL Summit Makalu | 44,995 dollars | 88 dB | 4 ohm | 2025 |
| JBL K2 S9900 | 44,000 dollars | 93 dB | 8 ohm | 2010 |
| JBL 4369 | 23,200 dollars | 93 dB | 6 ohm | 2025 |
| JBL 4367 | 16,500 dollars | 94 dB | 6 ohm | 2015 |
| JBL S4700 | 15,000 dollars | 94 dB | 6 ohm | 2012 |
Every other expensive JBL floorstander we hold is 93 dB or better and 6 or 8 ohms. The Makalu is 88 dB and 4 ohms. Across all 17, the only one that matches its 88 dB is the JBL Studio 680, which costs 1,198 dollars, and the Studio 680 is 6 ohms, so the Makalu is the harder load of the pair.
The D2830K compression driver in the throat of the Makalu's Sonoglass HDI horn
That is a real change of direction for a brand built on horns and high sensitivity, and the horn is still there. The Makalu's is a Sonoglass High-Definition Imaging horn with a 3 inch D2830K compression driver in its throat, crossed over at 1100 Hz. Below it sit an 8 inch midrange and a 12 inch woofer, both with JBL's HC4 cone, crossed at 285 Hz. The efficiency went somewhere else.
But 88 dB is ordinary at this price
Here is the part that stops this being a cheap shot. We hold 62 floorstanding speakers over 30,000 dollars with a published sensitivity, and 20 of them are 88 dB or lower. Big expensive speakers are often hard to drive. The Magnepan 30.7 costs exactly the same 44,995 dollars and is 86 dB into 4 ohms.
So the Makalu is normal for its price and unusual for its badge. If you are coming to it from other speakers at this money, nothing here will surprise you. If you are coming to it from a JBL, it will.
The Summit Series is five models now
The Makalu was not a standalone launch. JBL announced it at HIGH END Munich in May 2025 together with two smaller models, and in the same press release folded the Everest and the K2 into the same range. JBL's site now lists five Summit speakers.
| Model | Price a pair | Configuration |
|---|
| Summit Everest | 159,990 dollars, not shipping | 3.5-way, two 15 inch woofers |
| Summit K2 | 99,900 dollars, not shipping | 3-way, one 15 inch woofer |
| Summit Makalu | 44,995 dollars | 3-way, one 12 inch woofer |
| Summit Pumori | 29,995 dollars | 3-way, one 10 inch woofer |
| Summit Ama | 19,995 dollars with stands | 2-way, one 8 inch woofer |
The top two are the reason our own JBL pages need a warning. The Summit Everest is a new speaker, not a rebadge: three 2 inch compression drivers on a manifold into one horn, two 10 inch mid-bass drivers and two 15 inch woofers. The Everest DD67000 and K2 S9900 rows we hold are the models it and the Summit K2 replace, dated 2013 and 2010. They are still worth comparing against, and I have left them on file, but they are the previous generation now.

What this post cannot tell you
Three things, and they all matter.
The bass depth is not comparable. JBL quotes the Makalu at 23 Hz to 33 kHz at -6 dB, and again at 20 Hz to 34 kHz at -10 dB. It publishes no plus or minus 3 dB figure. Most of our database is stored at plus or minus 3 dB, and a -6 dB number always reads lower than a plus or minus 3 dB one on the same speaker. So our 23 Hz is not the same kind of 23 Hz as the one on a Bowers or a KEF page, and you should not rank them against each other on that row.
The Summit Everest and Summit K2 prices are a dealer's, not JBL's. Both read "Coming Soon" at Definitive Audio and JBL has published no price for either. I have deliberately not created database rows for them. A pre-order figure in a price field is a guess wearing a number's clothes, and it would rank against real prices as though it were one.
I have not heard it. Everything above is arithmetic on published figures. Sensitivity and impedance tell you what amplifier to bring. They tell you nothing at all about whether you will like it.

Questions answered
How much does the JBL Summit Makalu cost?
44,995 dollars a pair. That is JBL's launch price from May 2025. Definitive Audio, the US launch dealer, lists it at 44,999.90. Hi-Fi News quotes 36,998 pounds in the UK.
What amplifier does the JBL Summit Makalu need?
Our amplifier matcher asks for at least 160 watts a channel into 4 ohms to reach 102 dB peaks at four metres in a large room, and says more than 300 watts stops buying you anything. JBL itself rates the speaker for 25 to 300 watts. Pick an amplifier that is rated into 4 ohms, because the Makalu drops to 3.5 ohms at 79 Hz.
Is the JBL Summit Makalu hard to drive?
Harder than any other big JBL we hold, and about average for a floorstanding speaker over 30,000 dollars. At 88 dB and 4 ohms it needs roughly twelve times the power of the 96 dB, 8 ohm Everest DD67000 for the same loudness. Twenty of the 62 speakers we hold in its price class are 88 dB or lower.
Does the Summit Makalu replace the JBL K2 S9900?
No. The Summit Series has its own new K2, announced alongside the Makalu and not yet shipping. The Makalu sits below both the Summit K2 and the Summit Everest, and above the Pumori and the Ama.
What drivers does the JBL Summit Makalu use?
A 3 inch D2830K dual-diaphragm compression driver on a Sonoglass HDI horn, a JMW200SC 8 inch midrange and a JW300SC 12 inch woofer. Both cones are JBL's triple-layer HC4, carbon fibre and pure pulp around a closed-cell foam core. Crossovers are at 285 Hz and 1100 Hz, and the cabinet is ported at the rear through two flared ports.
How big is the JBL Summit Makalu?
1102 by 464 by 393 mm with the grille on, and 69.2 kg each. That is about 43 by 18 by 15 and a half inches, and 153 pounds.
So if you were spending 45,000 dollars on a pair of JBLs, would you take the new Makalu and buy an amplifier to suit it, or the K2 S9900 that runs happily on 25 watts?
