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 BR04 and Borea BR03 have the same Impedance of 8 ohms and their sensitivity is also same at 90 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.
Borea BR04 can handle a max power of 110 watts RMS from the amp the whereas Borea BR03 has a max power handling value of 100 watts RMS, 10 watts less than the Borea BR04.
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 BR04 features Dual binding posts posts which make bi-amping or bi-wiring possible. Borea BR03 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Borea BR04 and Borea BR03 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 Triangle Borea BR04's and Triangle Borea BR03's external dimensions. Triangle Borea BR04 has external dimensions of 425.0 x 220.0 x 314.0mm ( 16.7 x 8.7 x 12.3inch) whereas Triangle Borea BR03 has external dimensions of 380.0 x 206.0 x 314.0mm ( 14.9 x 8.1 x 12.3inch) .
Triangle Borea BR03 is 14mm narrower and 45mm shorter than Triangle Borea BR04 but they have the same thickness of 314.0mm.
Below you can see the front view size comparison of Triangle Borea BR04 and Triangle Borea BR03 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 BR04 is approximately 690.0cm2 / 107.0inch2 and base area of the Triangle Borea BR03 is approximately 646.8cm2 / 100.3inch2. The Borea BR04 requires 7% more surface area than the Borea BR03 which gives it a small disadvantage 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 BR04 weighs 8.60kg / 18.9lbs and the Triangle Borea BR03 weighs 6.26kg / 13.8lbs. This makes the Borea BR04 37% heavier than the Borea BR03.
