Aon 2 features a " Folded Ribbon Tweeter and 1 x 6" Polypropylene Woofer. On the other hand, the TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Aon 2 has a frequency range of 42-35k Hz whereas TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 42Hz, the Aon 2 can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
Aon 2 and TSi100 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.
Sensitivity
Bookshelf 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.
Aon 2 can handle a max power of 200 watts RMS, whereas TSi100 has a max power handling value of 100 watts RMS, 100 watts less than the Aon 2.
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
Aon 2 features Pair of 5-way Binding Posts - Gold-Plated type posts and TSi100 has a Pair of 5-way Binding Posts - Gold-Plated type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Aon 2 and TSi100 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 GoldenEar Aon 2's and Polk TSi100's external dimensions. GoldenEar Aon 2 has external dimensions of 305.0 x 204.0 x 258.0mm (12 x 8 x 10-1/8inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm (11.0 x 7.0 x 10.1inch).
Polk TSi100 is 26.2mm narrower and 25.6mm shorter than GoldenEar Aon 2 but it is also 1mm deeper.
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 GoldenEar Aon 2 is approximately 526.3cm2 / 81.6inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The Aon 2 requires 14% more surface area than the TSi100 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 GoldenEar Aon 2 weighs 5.45kg / 12lbs and the Polk TSi100 weighs 4.53kg / 10lbs. This makes the Aon 2 20% heavier than the TSi100.
Here is a comparison of how Aon 2 and TSi100's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - GoldenEar Aon 2 costs roughly 6x what Polk TSi100 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass |
A |
GoldenEar Aon 2 digs deeper - 42Hz against 61Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (89dB vs 89dB) - both want much the same power. |
| Headroom |
A |
GoldenEar Aon 2 takes more power (200W vs 100W) - more in hand in a big room. |
| Size |
depends |
Similar cabinet size - neither is easier to fit. |
| Cabinet |
depends |
Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability |
depends |
Neither adds bi-amping, a sub output or height drivers. Polk TSi100 sits in a wider range (5 models), so a matched surround system is easier later. |
| Price |
B |
Polk TSi100 is cheaper - $149 against $898, about 83% less; arguably a different class. |

B Polk TSi100
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?
The usual trade-off: GoldenEar Aon 2 measures better, Polk TSi100 costs about 83% 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 61Hz anyway, which makes the cheaper Polk TSi100 much easier to justify. Match it to your room: we rate GoldenEar Aon 2 the better fit for a mid-size room and a large room, and Polk TSi100 for near-field listening and a small 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.
