What size room are the Mission ZX-3 and Monitor Audio Bronze 500 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:

position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

ZX-3 features a 1.5" Silk Ring Dome Tweeter and 1 x 5.25" Aluminium Woofer with a Crossover frequency at 2.4kHz. On the other hand, the Bronze 500 features a 1" gold dome C-CAM with uniform dispersion (UD) waveguide Tweeter and 2 x 8" C-CAM Woofer.
Frequency Response
ZX-3 has a frequency range of 42-24k Hz whereas Bronze 500 has a frequency range of 32-30k Hz. With a minimum frequency of 32Hz, the Bronze 500 can go significantly deeper on the low side and provide stronger bass compared to the ZX-3's min frequency of 42Hz.
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
ZX-3 is a 4 ohms speaker compared to the Bronze 500 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 ZX-3 can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.
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.
Bronze 500 can handle a max power of 200 watts RMS, whereas ZX-3 has a max power handling value of 150 watts RMS, 50 watts less than the Bronze 500.
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
Both ZX-3 and Bronze 500 features dual binding post speaker terminals for bi-amping or 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 Mission ZX-3's and Monitor Audio Bronze 500's external dimensions. Mission ZX-3 has external dimensions of 1025.0 x 240.0 x 362.0mm (40-3/8 x 9-7/16 x 14-1/4inch) whereas Monitor Audio Bronze 500 has external dimensions of 977.0 x 294.0 x 366.0mm (38-7/16 x 11-9/16 x 14-3/8inch).
Mission ZX-3 is 54mm narrower and 4mm less deeper than Monitor Audio Bronze 500 but it is also 48mm taller.
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.
Monitor Audio Bronze 500 needs about 24% more floor or shelf area. Mission ZX-3 is 48mm 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 Mission ZX-3 is approximately 868.8cm2 / 134.7inch2 and base area of the Monitor Audio Bronze 500 is approximately 1076.0cm2 / 166.8inch2. The ZX-3 requires 19% less surface area than the Bronze 500 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 Mission ZX-3 weighs 20.40kg / 44.9lbs and the Monitor Audio Bronze 500 weighs 18.05kg / 39.7lbs. This makes the ZX-3 13% heavier than the Bronze 500.
Here is a comparison of how ZX-3 and Bronze 500'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 | Monitor Audio Bronze 500 digs deeper - 32Hz against 42Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (90dB vs 90dB) - both want much the same power. |
| Amplifier match | B | Monitor Audio Bronze 500 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | Monitor Audio Bronze 500 takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | B | Mission ZX-3: bi-amping; Monitor Audio Bronze 500: bi-amping and Atmos drivers. |
| Price | evenly matched | Much the same money ($1,499 vs $1,496 a pair). |
A Mission ZX-3 B Monitor Audio Bronze 500
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 500 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 42Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Mission ZX-3 the better fit for a small room, and Monitor Audio Bronze 500 for a 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.
