History
What size room are the KEF Q3 Meta and KEF Q Concerto Meta 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:

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
One of the fundamental differences between these two speakers is that Q3 Meta is a 2-way design whereas the Q Concerto Meta is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Q3 Meta features a 1" vented aluminum dome with MAT absorber Hard dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2.0 kHz. On the other hand, the Q Concerto Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter, a 4" Midrange and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 430 Hz, 2.9 kHz.
Frequency Response
Q3 Meta has a frequency range of 49-20k Hz whereas Q Concerto Meta has a frequency range of 48-20k Hz. With a minimum frequency of 48Hz, the Q Concerto Meta can go slightly deeper then the Q3 Meta's min frequency of 49Hz.
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
Q3 Meta and Q Concerto Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Q3 Meta sensitivity is rated at 87 dB and the Q Concerto Meta's is at 85 dB. This 2 dB difference makes the KEF Q3 Meta a more sensitive speaker compared to KEF Q Concerto Meta, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Q3 Meta and the Q3 Meta can provide this impedance level.
Sensitivity

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.
Q Concerto Meta can handle a max power of 180 watts RMS, whereas Q3 Meta has a max power handling value of 150 watts RMS, 30 watts less than the Q Concerto Meta.
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
Q3 Meta features Binding Post type posts and Q Concerto Meta has a Binding Post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Q3 Meta and Q Concerto Meta 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 KEF Q3 Meta's and KEF Q Concerto Meta's external dimensions. KEF Q3 Meta has external dimensions of 357 x 210 x 305 mm (14.1 x 8.3 x 12.0 in.) whereas KEF Q Concerto Meta has external dimensions of 415 x 210 x 315 mm (16.3 x 8.3 x 12.4 in.).
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 KEF Q3 Meta is approximately 640.5cm2 / 99.3inch2 and base area of the KEF Q Concerto Meta is approximately 661.5cm2 / 102.5inch2. The Q3 Meta requires 3% less surface area than the Q Concerto Meta 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 KEF Q3 Meta weighs 8.23kg / 18.1lbs and the KEF Q Concerto Meta weighs 9.50kg / 20.9lbs. This makes the Q Concerto Meta 15% heavier than the Q3 Meta.
Here is a comparison of how Q3 Meta and Q Concerto Meta's weights compare with the average, max and min weights in Passive Bookshelf class.

Siblings in KEF's Q Meta series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (49Hz vs 48Hz). |
| Amplifier needs | A | KEF Q3 Meta is more sensitive (87dB vs 85dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (150W vs 180W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Price | A | KEF Q3 Meta is cheaper - $800 against $1,300, about 38% less; arguably a different class. |
A KEF Q3 Meta B KEF Q Concerto Meta
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?
KEF Q3 Meta 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 your amplifier is modest, vintage or valve-based, KEF Q3 Meta is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $500 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
