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 KEF Q750 and Triangle Borea BR07 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Q750 is a 2-way design whereas the Borea BR07 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.

Q750 features a 1" vented aluminum Dome Tweeter and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz. On the other hand, the Borea BR07 features a 1" silk Break_in Tweeter , a 6" Midrange and 1 x 6" fiberglass Woofer with a Crossover frequency at 350Hz and 3500Hz.
Frequency Response
Q750 has a frequency range of 48-28k Hz whereas Borea BR07 has a frequency range of 44 - 22k Hz. With a minimum frequency of 44Hz, the Borea BR07 can go slightly deeper then the Q750's min frequency of 48Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing Speakers
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
Q750 and Borea BR07 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Q750 sensitivity is rated at 88 dB and the Borea BR07's is at 91 dB. This 3 dB difference makes the Triangle Borea BR07 a more sensitive speaker compared to KEF Q750, 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.
Q750 can handle a max power of 150 watts RMS from the amp the whereas Borea BR07 has a max power handling value of 120 watts RMS, 30 watts less than the Q750.
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
Q750 features Binding post type posts and Borea BR07 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Q750 and Borea BR07 have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 Q750's and Triangle Borea BR07's external dimensions. KEF Q750 has external dimensions of 945.0 x 328.0 x 315.0mm ( 37-3/16 x 12-7/8 x 12-3/8inch) whereas Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm ( 38.5 x 8.1 x 12.3inch) .
Triangle Borea BR07 is 122mm narrower and 1mm less deeper than KEF Q750 but it is also 35mm 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 KEF Q750 is approximately 1033.2cm2 / 160.1inch2 and base area of the Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The Q750 requires 60% more surface area than the Borea BR07 which gives it a small disadvantage on placement in tight spaces.
