In this review, we will be comparing Q150 and M126Be, two Passive Bookshelf speakers from KEF and Revel. Let's have a brief look at the main features
of KEF Q150 and Revel M126Be first before getting into our more
detailed comparison.
What size room are the KEF Q150 and Revel M126Be 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:
In the following sections, we will get into more detail in order to better understand how the KEF Q150 and Revel M126Be compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Q150 features a 1" vented aluminum Dome Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2500Hz. On the other hand, the M126Be features a 1" beryllium Hard-Dome Tweeter and 1 x 6.5" DCC Aluminum Woofer .
Frequency Response
Q150 has a frequency range of 51-28k Hz whereas M126Be has a frequency range of 54-44k Hz. With a minimum frequency of 51Hz, the Q150 can go slightly deeper then the M126Be's min frequency of 54Hz.
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.

High Frequency

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
Q150 and M126Be have the same Impedance of 8 ohms and their sensitivity is also same at 86 dB.
Sensitivity

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.
Q150 can handle a max power of 150 watts RMS from the amp the whereas Q150 has a max power handling value of 100 watts RMS , 50 watts less than the M126Be.
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
Q150 features Binding post type posts and M126Be has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Q150 and M126Be 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 KEF Q150's and Revel M126Be's external dimensions. KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm ( 11.9 x 7.0 x 10.9inch) whereas Revel M126Be has external dimensions of 388.0 x 212.0 x 262.0mm ( 15-1/4 x 8-5/16 x 10-5/16inch) .
KEF Q150 is 32mm narrower and 85mm shorter than Revel M126Be but it is also 16mm deeper.
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 Q150 is approximately 500.4cm2 / 77.6inch2 and base area of the Revel M126Be is approximately 555.4cm2 / 86.1inch2. The Q150 requires 10% less surface area than the M126Be 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 Q150 weighs 5.60kg / 12.3lbs and the Revel M126Be weighs 10.00kg / 22lbs. This makes the M126Be 79% heavier than the Q150.
Here is a comparison of how Q150 and M126Be's weights compare with the average, max and min weights in Passive Bookshelf class.
