What size room are the JBL A130 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:

400 sq. ft / 36 m2.
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.)
In the following sections, we will get into more detail in order to better understand how the JBL A130 and KEF Q150 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

A130 features a 1" aluminum Hard-Dome Tweeter and 1 x 5.25" Polycellulose Woofer . 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
A130 has a frequency range of 55-40k Hz whereas Q150 has a frequency range of 51-28k Hz. With a minimum frequency of 51Hz, the Q150 can go slightly deeper then the A130's min frequency of 55Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
A130 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.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
A130 can handle a max power of 125 watts RMS from the amp the whereas Q150 has a max power handling value of 100 watts RMS, 25 watts less than the A130.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
A130 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 A130 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
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL A130's and KEF Q150's external dimensions. JBL A130 has external dimensions of 323.0 x 191.0 x 250.0mm ( 12-11/16 x 7-1/2 x 9-13/16inch) 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 11mm narrower and 20mm shorter than JBL A130 but it is also 28mm deeper.
Below you can see the front view size comparison of JBL A130 and KEF Q150 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 JBL A130 is approximately 477.5cm2 / 74.0inch2 and base area of the KEF Q150 is approximately 500.4cm2 / 77.6inch2. The A130 requires 5% less surface area than the Q150 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 JBL A130 weighs 5.46kg / 12lbs and the KEF Q150 weighs 5.60kg / 12.3lbs. This makes the Q150 3% heavier than the A130.
Here is a comparison of how A130 and Q150's weights compare with the average, max and min weights in Passive Bookshelf class.
