Borea BR02 features a 1" silk Tweeter and 1 x 5" fiberglass Woofer with a Crossover frequency at 2900Hz. 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
Borea BR02 has a frequency range of 51 - 22k Hz whereas Q150 has a frequency range of 51-28k Hz.
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
Borea BR02 and Q150 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Borea BR02 sensitivity is rated at 89 dB and the Q150's is at 86 dB. This 3 dB difference makes the Triangle Borea BR02 a more sensitive speaker compared to KEF Q150, hence will play louder with the same amount of watts.

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.
Borea BR02 can handle a max power of 100 watts RMS from the amp the whereas Borea BR02 has a max power handling value of 80 watts RMS , 20 watts less than the Q150.
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
Borea BR02 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 Borea BR02 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 Triangle Borea BR02's and KEF Q150's external dimensions. Triangle Borea BR02 has external dimensions of 310.0 x 176.0 x 274.0mm ( 12.2 x 6.9 x 10.7inch) whereas KEF Q150 has external dimensions of 303.0 x 180.0 x 278.0mm ( 11.9 x 7.0 x 10.9inch) .
Triangle Borea BR02 is 4mm narrower and 4mm less deeper than KEF Q150 but it is also 7mm taller.
Below you can see the front view size comparison of Triangle Borea BR02 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 Triangle Borea BR02 is approximately 482.2cm2 / 74.7inch2 and base area of the KEF Q150 is approximately 500.4cm2 / 77.6inch2. The Borea BR02 requires 4% 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 Triangle Borea BR02 weighs 4.87kg / 10.7lbs and the KEF Q150 weighs 5.60kg / 12.3lbs. This makes the Q150 15% heavier than the Borea BR02.
Here is a comparison of how Borea BR02 and Q150's weights compare with the average, max and min weights in Passive Bookshelf class.
