History
What size room are the KEF Q1 Meta and KEF Q11 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 Q1 Meta is a 2-way design whereas the Q11 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.

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. On the other hand, the Q11 Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter, a 4" Midrange and 3 x 6.5" Aluminum Woofer with a Crossover frequency at 480 Hz, 2.7 kHz.
Frequency Response
Q1 Meta has a frequency range of 51-20k Hz whereas Q11 Meta has a frequency range of 44-20k Hz. With a minimum frequency of 44Hz, the Q11 Meta can go significantly deeper on the low side and provide stronger bass compared to 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
Q1 Meta and Q11 Meta have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Q1 Meta sensitivity is rated at 86 dB and the Q11 Meta's is at 89 dB. This 3 dB difference makes the KEF Q11 Meta a more sensitive speaker compared to KEF Q1 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 Q1 Meta and the Q1 Meta can provide this impedance level.

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.
Q11 Meta can handle a max power of 225 watts RMS, whereas Q1 Meta has a max power handling value of 150 watts RMS, 75 watts less than the Q11 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
Q1 Meta features Binding Post type posts and Q11 Meta has a Binding Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Q1 Meta and Q11 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 Q1 Meta's and KEF Q11 Meta's external dimensions. KEF Q1 Meta has external dimensions of 302 x 180 x 277 mm (11.9 x 7.1 x 10.9 in.) whereas KEF Q11 Meta has external dimensions of 1112 x 317 x 380 mm (43.8 x 12.5 x 15.0 in.).
KEF Q11 Meta is clearly the larger of the two speakers. Its body is 137mm wider, 810mm taller and 103mm deeper than KEF Q1 Meta.
Below you can see the front view size comparison of KEF Q1 Meta and KEF Q11 Meta in scale.

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 Q1 Meta is approximately 498.6cm2 / 77.3inch2 and base area of the KEF Q11 Meta is approximately 1204.6cm2 / 186.7inch2. The Q1 Meta requires 59% less surface area than the Q11 Meta which gives it a small advantage on placement in tight spaces.
