Everest DD67000 features a 4" Beryllium Compression Driver Tweeter and 2 x 15" Pure Pulp sandwich Woofer with a Crossover frequency at 150Hz, 850Hz and 20000Hz. On the other hand, the K2 S9900 features a 4" Magnesium Compression Driver Tweeter and 1 x 15" Pure Pulp Woofer with a Crossover frequency at 900Hz and 15000Hz.
Frequency Response
Everest DD67000 has a frequency range of 29-60k Hz whereas K2 S9900 has a frequency range of 48-50k Hz. With a minimum frequency of 29Hz, the Everest DD67000 can go significantly deeper on the low side and provide stronger bass compared to the K2 S9900's min frequency of 48Hz.
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
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Everest DD67000 and K2 S9900 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Everest DD67000 sensitivity is rated at 96 dB and the K2 S9900's is at 93 dB. This 3 dB difference makes the JBL Everest DD67000 a more sensitive speaker compared to JBL K2 S9900, hence will play louder with the same amount of watts.
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.
Everest DD67000 and K2 S9900 have the same power range of up to 500 watts.
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 Everest DD67000 and K2 S9900 features dual binding post speaker terminals for bi-amping or bi-wiring.
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 Everest DD67000's and JBL K2 S9900's external dimensions. JBL Everest DD67000 has external dimensions of 1109.0 x 965.0 x 470.0mm (43-11/16 x 38 x 18-1/2inch) whereas JBL K2 S9900 has external dimensions of 1200.0 x 560.0 x 350.0mm (47-1/4 x 22-1/16 x 13-3/4inch).
JBL K2 S9900 is 405mm narrower and 120mm less deeper than JBL Everest DD67000 but it is also 91mm taller.
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 Everest DD67000 needs about 131% more floor or shelf area. JBL Everest DD67000 is 120mm deeper, so it stands that much further out from the wall. JBL K2 S9900 is 91mm 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 Everest DD67000 is approximately 4535.5cm2 / 703.0inch2 and base area of the JBL K2 S9900 is approximately 1960.0cm2 / 303.8inch2. The Everest DD67000 requires 131% more surface area than the K2 S9900 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 Everest DD67000 weighs 142.10kg / 312.6lbs and the JBL K2 S9900 weighs 82.70kg / 181.9lbs. This makes the Everest DD67000 72% heavier than the K2 S9900.
Here is a comparison of how Everest DD67000 and K2 S9900's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in JBL's Project series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | JBL Everest DD67000 digs deeper - 29Hz against 48Hz. |
| Amplifier needs | A | JBL Everest DD67000 is more sensitive (96dB vs 93dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (500W vs 500W). |
| Size | depends | JBL K2 S9900 is easier to place; JBL Everest DD67000 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | JBL Everest DD67000: bi-amping; JBL K2 S9900: bi-amping. |
| Price | B | JBL K2 S9900 is cheaper - $44,000 against $75,000, about 41% less; arguably a different class. |
A JBL Everest DD67000 B JBL K2 S9900
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 Everest DD67000 measures better, JBL K2 S9900 costs about about 70% more% 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 48Hz anyway, which makes the cheaper JBL K2 S9900 much easier to justify. In a large or open-plan room, JBL Everest DD67000 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, JBL K2 S9900 is the easier speaker to get right.
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.
