History
What size room are the KEF Q Concerto Meta and KEF Q1 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 Q Concerto Meta is a 3-way design whereas the Q1 Meta is a 2-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.

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. On the other hand, the Q1 Meta features a 1" vented aluminum dome with MAT absorber Hard dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2.1 kHz.
Frequency Response
Q Concerto Meta has a frequency range of 48-20k Hz whereas Q1 Meta has a frequency range of 51-20k Hz. With a minimum frequency of 48Hz, the Q Concerto Meta can go slightly deeper then the Q1 Meta's min frequency of 51Hz.
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
Q Concerto Meta and Q1 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Q Concerto Meta sensitivity is rated at 85 dB and the Q1 Meta's is at 86 dB. This 1 dB difference makes the KEF Q1 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 Q Concerto Meta and the Q Concerto Meta can provide this impedance level.
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.
Q Concerto Meta can handle a max power of 180 watts RMS, whereas Q1 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
Q Concerto Meta features Binding Post type posts and Q1 Meta has a Binding Post type posts. None of these speakers feature bi-amping/bi-wiring.
KEF Q1 Meta's Binding Post terminals
Cabinet Type and Port Position
Both Q Concerto Meta and Q1 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 Q Concerto Meta's and KEF Q1 Meta's external dimensions. KEF Q Concerto Meta has external dimensions of 415 x 210 x 315 mm (16.3 x 8.3 x 12.4 in.) whereas KEF Q1 Meta has external dimensions of 302 x 180 x 277 mm (11.9 x 7.1 x 10.9 in.).
KEF Q Concerto Meta is clearly the larger of the two speakers. Its body is 30mm wider, 113mm taller and 38mm deeper than KEF Q1 Meta.
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.
KEF Q Concerto Meta needs about 33% more floor or shelf area. KEF Q Concerto Meta is 38mm deeper, so it stands that much further out from the wall. KEF Q Concerto Meta is 113mm 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 KEF Q Concerto Meta is approximately 661.5cm2 / 102.5inch2 and base area of the KEF Q1 Meta is approximately 498.6cm2 / 77.3inch2. The Q Concerto Meta requires 33% more surface area than the Q1 Meta 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 KEF Q Concerto Meta weighs 9.50kg / 20.9lbs and the KEF Q1 Meta weighs 6.09kg / 13.4lbs. This makes the Q Concerto Meta 56% heavier than the Q1 Meta.
Here is a comparison of how Q Concerto Meta and Q1 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 | A | KEF Q Concerto Meta digs deeper - 48Hz against 51Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (85dB vs 86dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (180W vs 150W). |
| Size | depends | KEF Q1 Meta is easier to place; KEF Q Concerto Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | KEF Q1 Meta is cheaper - $600 against $1,300, about 54% less; arguably a different class. |
A KEF Q Concerto Meta B KEF Q1 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 Q Concerto Meta is ahead, but only on 1 of the measured areas, and it costs about 117% more. That is a lot of money for a narrow margin on paper - KEF Q1 Meta looks like the sensible buy unless something else about the KEF Q Concerto Meta appeals to you. In a large or open-plan room, KEF Q Concerto Meta has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF Q1 Meta is the easier speaker to get right. Think about the whole system, not just the speakers: the roughly $700 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.
