What size room are the Q Acoustics 3010 and KEF Q150 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:

3010 features a 1" Dome Tweeter and 1 x 4" Paper composite Woofer with a Crossover frequency at 2800Hz. On the other hand, the Q150 features a 1" vented aluminum Dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
3010 has a frequency range of 68-22k Hz whereas Q150 has a frequency range of 51-28k Hz. With a minimum frequency of 51Hz, the Q150 can go significantly deeper on the low side and provide stronger bass compared to the 3010's min frequency of 68Hz.
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
3010 is a 6 ohms speaker compared to the Q150 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 86 dBdB.
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.
Q150 can handle a max power of 100 watts RMS, whereas 3010 has a max power handling value of 75 watts RMS, 25 watts less than the Q150.
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
3010 features Post type posts and Q150 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
KEF Q150's Post terminals
Cabinet Type and Port Position
Both 3010 and Q150 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 Q Acoustics 3010's and KEF Q150's external dimensions. Q Acoustics 3010 has external dimensions of 239.0 x 150.0 x 205.0mm (9-7/16 x 5-7/8 x 8-1/16inch) whereas KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm (11.9 x 7.0 x 10.9inch).
KEF Q150 is clearly the larger of the two speakers. Its body is 30mm wider, 64mm taller and 73mm deeper than Q Acoustics 3010.
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 Q150 needs about 63% more floor or shelf area. KEF Q150 is 73mm deeper, so it stands that much further out from the wall. KEF Q150 is 64mm 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 Q Acoustics 3010 is approximately 307.5cm2 / 47.7inch2 and base area of the KEF Q150 is approximately 500.4cm2 / 77.6inch2. The 3010 requires 39% less surface area than the Q150 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 Q Acoustics 3010 weighs 3.60kg / 7.9lbs and the KEF Q150 weighs 5.60kg / 12.3lbs. This makes the Q150 56% heavier than the 3010.
Here is a comparison of how 3010 and Q150's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - KEF Q150 costs roughly 5x what Q Acoustics 3010 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | KEF Q150 digs deeper - 51Hz against 68Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (86dB vs 86dB) - both want much the same power. |
| Amplifier match | B | KEF Q150 is the easier load at 8 ohms. |
| Headroom | B | KEF Q150 takes more power (100W vs 75W) - more in hand in a big room. |
| Size | depends | Q Acoustics 3010 is easier to place; KEF Q150 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. KEF Q150 sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | A | Q Acoustics 3010 is cheaper - $119 against $600, about 80% less; arguably a different class. |
A Q Acoustics 3010 B KEF Q150
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?
The usual trade-off: KEF Q150 measures better, Q Acoustics 3010 costs about about 5x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 68Hz anyway, which makes the cheaper Q Acoustics 3010 much easier to justify. Match it to your room: we rate Q Acoustics 3010 the better fit for near-field listening; elsewhere the two are rated the same.
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.
