The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both AE509 and Triton Five are 2-way speakers.

AE509 features a 1" carbon fibre dome with waveguide Tweeter and 2 x 5" carbon fibre cone Woofer with a Crossover frequency at 2800Hz. On the other hand, the Triton Five features a " Folded Ribbon Tweeter and 2 x 6" Polypropylene Woofer.
Frequency Response
AE509 has a frequency range of 32Hz - 28kHz whereas Triton Five has a frequency range of 26-35k Hz. With a minimum frequency of 26Hz, the Triton Five can go significantly deeper on the low side and provide stronger bass compared to the AE509's min frequency of 32Hz.
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
AE509 is a 6 ohms speaker compared to the Triton Five which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AE509 sensitivity is rated at 89 dB and the Triton Five's is rated at 90 dB. This 1 dB difference makes the GoldenEar Triton Five a more sensitive speaker compared to AE509, 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 Five can handle a max power of 400 watts RMS, whereas AE509 has a max power handling value of 175 watts RMS, 225 watts less than the Triton Five.
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.
Cabinet Type and Port Position
Both AE509 and Triton Five 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 AE509's and GoldenEar Triton Five's external dimensions. AE509 has external dimensions of 1000.0 x 185.0 x 270.0mm (39.4 x 7.3 x 10.6inch) whereas GoldenEar Triton Five has external dimensions of 1131.0 x 281.0 x 421.0mm (44-1/2 x 11-1/16 x 16-9/16inch).
GoldenEar Triton Five is clearly the larger of the two speakers. Its body is 96mm wider, 131mm taller and 151mm deeper than AE509.
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 AE509 is approximately 499.5cm2 / 77.4inch2 and base area of the GoldenEar Triton Five is approximately 1183.0cm2 / 183.4inch2. The AE509 requires 58% less surface area than the Triton Five which gives it a small advantage 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 AE509 weighs 22.00kg / 48.4lbs and the GoldenEar Triton Five weighs 18.18kg / 40lbs. This makes the AE509 21% heavier than the Triton Five.
Here is a comparison of how AE509 and Triton Five's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: AE509 is the newer design, against a 2014 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | GoldenEar Triton Five digs deeper - 26Hz against 32Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 90dB) - both want much the same power. |
| Amplifier match | B | GoldenEar Triton Five is the easier load at 8 ohms. |
| Headroom | B | GoldenEar Triton Five takes more power (400W vs 175W) - more in hand in a big room. |
| Size | depends | AE509 is easier to place; GoldenEar Triton Five is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Passive Radiator. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. GoldenEar Triton Five sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | B | GoldenEar Triton Five is cheaper - $2,398 against $3,499, about 31% less. |
A AE509 B GoldenEar Triton Five
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?
GoldenEar Triton Five is the easier recommendation: it leads on most of the measured areas and costs less. Take AE509 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 32Hz anyway, so judge these on the other rows instead. Match it to your room: we rate AE509 the better fit for a mid-size room, and GoldenEar Triton Five for a very large room.
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.
