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
Theva No1 and Borea BR02 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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.
Theva No1 can handle a max power of 120 watts RMS from the amp the whereas Borea BR02 has a max power handling value of 80 watts RMS, 40 watts less than the Theva No1.
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
Theva No1 features Binding post posts which make bi-amping or bi-wiring possible. Borea BR02 has a Binding post which doesn't feature bi-amping/bi-wiring.
Focal Theva No1's Binding post terminals allows Bi-amping or bi-wiring
Triangle Borea BR02's Binding post terminals
Cabinet Type and Port Position
Both Theva No1 and Borea BR02 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 Focal Theva No1's and Triangle Borea BR02's external dimensions. Focal Theva No1 has external dimensions of 391.0 x 213.0 x 261.0mm ( 153/8 x 83/8 x 101/4) whereas Triangle Borea BR02 has external dimensions of 310.0 x 176.0 x 274.0mm ( 12.2 x 6.9 x 10.7inch) .
Triangle Borea BR02 is 37mm narrower and 81mm shorter than Focal Theva No1 but it is also 13mm 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 Focal Theva No1 is approximately 555.9cm2 / 86.2inch2 and base area of the Triangle Borea BR02 is approximately 482.2cm2 / 74.7inch2. The Theva No1 requires 15% more surface area than the Borea BR02 which gives it a small disadvantage on placement in tight spaces.
