Aon 3 Bookshelf Monitor features a " Folded Ribbon Tweeter and 1 x 7" Polypropylene Woofer. On the other hand, the Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz.
Frequency Response
Aon 3 Bookshelf Monitor has a frequency range of 38-35k Hz whereas Bronze 1 has a frequency range of 55-30k Hz. With a minimum frequency of 38Hz, the Aon 3 Bookshelf Monitor can go significantly deeper on the low side and provide stronger bass compared to the Bronze 1's min frequency of 55Hz.
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 3 Bookshelf Monitor and Bronze 1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aon 3 Bookshelf Monitor sensitivity is rated at 90 dB and the Bronze 1's is at 88 dB. This 2 dB difference makes the GoldenEar Aon 3 a more sensitive speaker compared to Monitor Audio Bronze 1, hence will play louder with the same amount of watts.
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 3 Bookshelf Monitor can handle a max power of 250 watts RMS, whereas Bronze 1 has a max power handling value of 70 watts RMS, 180 watts less than the Aon 3 Bookshelf Monitor.
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
Aon 3 Bookshelf Monitor features Post type posts and Bronze 1 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Aon 3 Bookshelf Monitor and Bronze 1 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 3's and Monitor Audio Bronze 1's external dimensions. GoldenEar Aon 3 has external dimensions of 356.0 x 229.0 x 281.0mm (14 x 9 x 11-1/16inch) whereas Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm (10.2 x 6.4 x 8.0inch).
GoldenEar Aon 3 is clearly the larger of the two speakers. Its body is 64mm wider, 96mm taller and 76mm deeper than Monitor Audio Bronze 1.
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.
GoldenEar Aon 3 needs about 90% more floor or shelf area. GoldenEar Aon 3 is 76mm deeper, so it stands that much further out from the wall. GoldenEar Aon 3 is 96mm 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 GoldenEar Aon 3 is approximately 643.5cm2 / 99.7inch2 and base area of the Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2. The Aon 3 Bookshelf Monitor requires 90% more surface area than the Bronze 1 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 3 weighs 6.82kg / 15lbs and the Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs. This makes the Aon 3 Bookshelf Monitor 95% heavier than the Bronze 1.
Here is a comparison of how Aon 3 Bookshelf Monitor and Bronze 1's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - GoldenEar Aon 3 costs roughly 4x what Monitor Audio Bronze 1 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 3 digs deeper - 38Hz against 55Hz. |
| Amplifier needs | A | GoldenEar Aon 3 is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | A | GoldenEar Aon 3 takes more power (250W vs 70W) - more in hand in a big room. |
| Size | depends | Monitor Audio Bronze 1 is easier to place; GoldenEar Aon 3 is bigger, which usually goes with fuller bass. Your room decides. |
| 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. Monitor Audio Bronze 1 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | B | Monitor Audio Bronze 1 is cheaper - $299 against $1,200, about 75% less; arguably a different class. |
A GoldenEar Aon 3 B Monitor Audio Bronze 1
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: GoldenEar Aon 3 measures better, Monitor Audio Bronze 1 costs about about 4x 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 55Hz anyway, which makes the cheaper Monitor Audio Bronze 1 much easier to justify. Match it to your room: we rate GoldenEar Aon 3 the better fit for a mid-size room and a large room, and Monitor Audio Bronze 1 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.
