What size room are the Mission QX-4 MKII 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:

QX-4 MKII features a 1.5" Textile Ring Dome Tweeter and 2 x 6.5" Composite fibre Woofer with a Crossover frequency at 2.2kHz. 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
QX-4 MKII has a frequency range of 36-24k Hz whereas Bronze 500 has a frequency range of 32-30k Hz. With a minimum frequency of 32Hz, the Bronze 500 can go slightly deeper then the QX-4 MKII's min frequency of 36Hz.
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
QX-4 MKII 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 QX-4 MKII can provide this impedance level.
These two speakers also have different sensitivity levels. QX-4 MKII sensitivity is rated at 88 dB and the Bronze 500's is rated at 90 dB. This 2 dB difference makes the Monitor Audio Bronze 500 a more sensitive speaker compared to Mission QX-4 MKII, 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.
Bronze 500 can handle a max power of 200 watts RMS, whereas QX-4 MKII 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 QX-4 MKII 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 QX-4 MKII's and Monitor Audio Bronze 500's external dimensions. Mission QX-4 MKII has external dimensions of 1000.0 x 220.0 x 345.0mm (39-3/8 x 8-11/16 x 13-9/16inch) 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 QX-4 MKII is 74mm narrower and 21mm less deeper than Monitor Audio Bronze 500 but it is also 23mm 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 42% more floor or shelf area. Monitor Audio Bronze 500 is 21mm deeper, so it stands that much further out from the wall. Mission QX-4 MKII is 23mm 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 QX-4 MKII is approximately 759.0cm2 / 117.6inch2 and base area of the Monitor Audio Bronze 500 is approximately 1076.0cm2 / 166.8inch2. The QX-4 MKII requires 29% 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 QX-4 MKII weighs 23.80kg / 52.4lbs and the Monitor Audio Bronze 500 weighs 18.05kg / 39.7lbs. This makes the QX-4 MKII 32% heavier than the Bronze 500.
Here is a comparison of how QX-4 MKII 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 36Hz. A subwoofer would even that out. |
| Amplifier needs | B | Monitor Audio Bronze 500 is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| 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 | Mission QX-4 MKII is easier to place; Monitor Audio Bronze 500 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Mission QX-4 MKII: bi-amping; Monitor Audio Bronze 500: bi-amping and Atmos drivers. Monitor Audio Bronze 500 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | A | Mission QX-4 MKII is cheaper - $1,299 against $1,496, about 13% less. |
A Mission QX-4 MKII 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 leads across most of the measured areas for a fairly modest premium, which makes it the easier pick if the budget stretches. Mission QX-4 MKII is the one to take if it does not. Match it to your room: we rate Mission QX-4 MKII the better fit for a very large room, and Monitor Audio Bronze 500 for a mid-size room. If your amplifier is modest, vintage or valve-based, Monitor Audio Bronze 500 is the safer partner - the other will want more current or more watts to sound its best.
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.
