Summit Everest features a 2" Teonex Compression Driver Tweeter, a 10" Midrange and 2 x 15" Hybrid Carbon Cellulose Composite (HC4) Woofer with a Crossover frequency at 270 Hz / 550 Hz / 850 Hz. On the other hand, the Summit Pumori features a 1.5" Teonex Compression Driver Tweeter, a 8" Midrange and 1 x 10" Hybrid Carbon Cellulose Composite (HC4) Woofer with a Crossover frequency at 285 Hz / 1250 Hz.
Frequency Response
Summit Everest has a frequency range of 20-23k Hz whereas Summit Pumori has a frequency range of 30-32k Hz. With a minimum frequency of 20Hz, the Summit Everest can go significantly deeper on the low side and provide stronger bass compared to the Summit Pumori's min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Impedance and Sensitivity
Summit Everest and Summit Pumori have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Summit Everest sensitivity is rated at 96 dB and the Summit Pumori's is at 87 dB. This 9 dB difference makes the JBL Summit Everest a more sensitive speaker compared to JBL Summit Pumori, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Summit Everest and the Summit Everest can provide this impedance level.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Summit Everest can handle a max power of 1200 watts RMS, whereas Summit Pumori has a max power handling value of 250 watts RMS, 950 watts less than the Summit Everest.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Summit Everest and Summit Pumori features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Summit Everest and Summit Pumori have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL Summit Everest's and JBL Summit Pumori's external dimensions. JBL Summit Everest has external dimensions of 1443.0 x 992.0 x 694.5mm (56-13/16 x 39-1/16 x 27-5/16inch) whereas JBL Summit Pumori has external dimensions of 1056.5 x 393.3 x 373.0mm (41-5/8 x 15-1/2 x 14-11/16inch).
JBL Summit Everest is clearly the larger of the two speakers. Its body is 598.7mm wider, 386.5mm taller and 321.5mm deeper than JBL Summit Pumori.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
JBL Summit Everest needs about 370% more floor or shelf area. JBL Summit Everest is 322mm deeper, so it stands that much further out from the wall. JBL Summit Everest is 387mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the JBL Summit Everest is approximately 6889.4cm2 / 1,067.9inch2 and base area of the JBL Summit Pumori is approximately 1467.0cm2 / 227.4inch2. The Summit Everest requires 370% more surface area than the Summit Pumori which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The JBL Summit Everest weighs 237.20kg / 521.8lbs and the JBL Summit Pumori weighs 63.90kg / 140.6lbs. This makes the Summit Everest 271% heavier than the Summit Pumori.
Here is a comparison of how Summit Everest and Summit Pumori's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in JBL's Summit series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | JBL Summit Everest digs deeper - 20Hz against 30Hz. |
| Amplifier needs | A | JBL Summit Everest is more sensitive (96dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | A | JBL Summit Everest takes more power (1200W vs 250W) - more in hand in a big room. |
| Size | depends | JBL Summit Pumori is easier to place; JBL Summit Everest is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | JBL Summit Everest: bi-amping; JBL Summit Pumori: bi-amping. |
| Price | B | JBL Summit Pumori is cheaper - $29,995 against $159,990, about 81% less; arguably a different class. |
A JBL Summit Everest B JBL Summit Pumori
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: JBL Summit Everest measures better, JBL Summit Pumori costs about about 5.3x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 30Hz anyway, which makes the cheaper JBL Summit Pumori much easier to justify. Match it to your room: we rate JBL Summit Everest the better fit for a very large room; elsewhere the two are rated the same.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
