What size room are the MartinLogan ESL 9 and GoldenEar Triton Two+ speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Drivers
One of the fundamental differences between these two speakers is that ESL 9 is a 2-way design whereas the Triton Two+ is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

ESL 9 features a 9.2 x 44" curved electrostatic transducer Tweeter and 2 x 8" high-excursion paper cone Woofer. On the other hand, the Triton Two+ features a " High-Velocity Folded Ribbon Tweeter, a 4.5" Midrange and 1 x 5" Polymer Woofer.
Frequency Response
ESL 9 has a frequency range of 34-23k Hz whereas Triton Two+ has a frequency range of 16-35k Hz. With a minimum frequency of 16Hz, the Triton Two+ can go significantly deeper on the low side and provide stronger bass compared to the ESL 9's min frequency of 34Hz.
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
ESL 9 is a 4 ohms speaker compared to the Triton Two+ which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the ESL 9 can provide this impedance level.
These two speakers also have different sensitivity levels. ESL 9 sensitivity is rated at 90 dB and the Triton Two+'s is rated at 91 dB. This 1 dB difference makes the GoldenEar Triton Two+ a more sensitive speaker compared to MartinLogan ESL 9, 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.
Triton Two+ can handle a max power of 500 watts RMS, whereas ESL 9 has a max power handling value of 400 watts RMS, 100 watts less than the Triton Two+.
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.

considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
ESL 9 features Binding post posts which make bi-amping or bi-wiring possible. Triton Two+ has a 5-Way post which doesn't feature bi-amping/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 MartinLogan ESL 9's and GoldenEar Triton Two+'s external dimensions. MartinLogan ESL 9 has external dimensions of 1520.0 x 266.0 x 647.0mm (59-13/16 x 10-7/16 x 25-7/16inch) whereas GoldenEar Triton Two+ has external dimensions of 1232.0 x 297.0 x 486.0mm (48-1/2 x 11-11/16 x 19-1/8inch).
GoldenEar Triton Two+ is 288mm shorter and 161mm less deeper than MartinLogan ESL 9 but it is also 31mm wider.
Below you can see the front view size comparison of MartinLogan ESL 9 and GoldenEar Triton Two+ in scale.

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 MartinLogan ESL 9 is approximately 1721.0cm2 / 266.8inch2 and base area of the GoldenEar Triton Two+ is approximately 1443.4cm2 / 223.7inch2. The ESL 9 requires 19% more surface area than the Triton Two+ 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 MartinLogan ESL 9 weighs 35.45kg / 78lbs and the GoldenEar Triton Two+ weighs 27.27kg / 60lbs. This makes the ESL 9 30% heavier than the Triton Two+.
Here is a comparison of how ESL 9 and Triton Two+'s weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass |
B |
GoldenEar Triton Two+ digs deeper - 16Hz against 34Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (90dB vs 91dB) - both want much the same power. |
| Amplifier match |
B |
GoldenEar Triton Two+ is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom |
B |
GoldenEar Triton Two+ takes more power (500W vs 400W) - more in hand in a big room. |
| Size |

GoldenEar Triton Two+ is easier to place; MartinLogan ESL 9 is bigger, which usually goes with fuller bass. Your room decides. |

A MartinLogan ESL 9

depends neither is better in the abstract - it turns on your room, placement 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?
GoldenEar Triton Two+ is the easier recommendation: it leads on most of the measured areas and costs less. Take MartinLogan ESL 9 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 34Hz anyway, so judge these on the other rows instead. In a large or open-plan room, MartinLogan ESL 9 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, GoldenEar Triton Two+ 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.
