History
What size room are the Monitor Audio Bronze 1 and Monitor Audio Bronze 50 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:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Bronze 1 and Bronze 50 are 2-way speakers.

Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz. On the other hand, the Bronze 50 features a 1" Hard-Dome Tweeter and 1 x 5.25" C-CAM Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Bronze 1 has a frequency range of 55-30k Hz whereas Bronze 50 has a frequency range of 40-30k Hz. With a minimum frequency of 40Hz, the Bronze 50 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
Bronze 1 and Bronze 50 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Bronze 1 sensitivity is rated at 88 dB and the Bronze 50's is at 85 dB. This 3 dB difference makes the Monitor Audio Bronze 1 a more sensitive speaker compared to Monitor Audio Bronze 50, 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.
Bronze 50 can handle a max power of 80 watts RMS, whereas Bronze 1 has a max power handling value of 70 watts RMS, 10 watts less than the Bronze 50.
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
Bronze 50 features Post posts which make bi-amping or bi-wiring possible. Bronze 1 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Bronze 1 and Bronze 50 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 Monitor Audio Bronze 1's and Monitor Audio Bronze 50's external dimensions. Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm (10.2 x 6.4 x 8.0inch) whereas Monitor Audio Bronze 50 has external dimensions of 281.0 x 166.0 x 265.0mm (11.0 x 6.5 x 10.4inch).
Monitor Audio Bronze 50 is clearly the larger of the two speakers. Its body is 1mm wider, 21mm taller and 60mm deeper than Monitor Audio Bronze 1.
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 Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2 and base area of the Monitor Audio Bronze 50 is approximately 439.9cm2 / 68.2inch2. The Bronze 1 requires 23% less surface area than the Bronze 50 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 Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs and the Monitor Audio Bronze 50 weighs 5.00kg / 11lbs. This makes the Bronze 50 43% heavier than the Bronze 1.
Here is a comparison of how Bronze 1 and Bronze 50's weights compare with the average, max and min weights in Passive Bookshelf class.

Siblings in Monitor Audio's Bronze series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Bronze 50 digs deeper - 40Hz against 55Hz. |
| Amplifier needs | A | Monitor Audio Bronze 1 is more sensitive (88dB vs 85dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (70W vs 80W). |
| Size | depends | Monitor Audio Bronze 1 is easier to place; Monitor Audio Bronze 50 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Monitor Audio Bronze 50: bi-amping. |
| Price | A | Monitor Audio Bronze 1 is cheaper - $299 against $550, about 46% less; arguably a different class. |
A Monitor Audio Bronze 1 B Monitor Audio Bronze 50
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?
Monitor Audio Bronze 50 is ahead, but only on 1 of the measured areas, and it costs about 84% more. That is a lot of money for a narrow margin on paper - Monitor Audio Bronze 1 looks like the sensible buy unless something else about the Monitor Audio Bronze 50 appeals to you. 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 Monitor Audio Bronze 1 the better fit for near-field listening; elsewhere the two are rated the same.
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.
