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
BP-9040 and Borea BR09 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BP-9040 sensitivity is rated at 92 dB and the Borea BR09's is at 92.5 dB. This 1 dB difference makes the Triangle Borea BR09 a more sensitive speaker compared to Definitive BP-9040, 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.
BP-9040 can handle a max power of 300 watts RMS from the amp the whereas Borea BR09 has a max power handling value of 170 watts RMS, 130 watts less than the BP-9040.
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
BP-9040 features Binding post type posts and Borea BR09 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

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 Definitive BP-9040's and Triangle Borea BR09's external dimensions. Definitive BP-9040 has external dimensions of 993.0 x 281.0 x 351.0mm ( 39-1/16 x 11-1/16 x 13-13/16inch) whereas Triangle Borea BR09 has external dimensions of 1095.0 x 206.0 x 314.0mm ( 43.1 x 8.1 x 12.3inch) .
Triangle Borea BR09 is 75mm narrower and 37mm less deeper than Definitive BP-9040 but it is also 102mm 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 Definitive BP-9040 is approximately 986.3cm2 / 152.9inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The BP-9040 requires 52% more surface area than the Borea BR09 which gives it a small disadvantage on placement in tight spaces.
