High Frequency
Bookshelf 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
Oberon 3 is a 6 ohms speaker compared to the Borea BR03 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 3 sensitivity is rated at 87 dB and the Borea BR03's is rated at 90 dB. This 3 dB difference makes the Triangle Borea BR03 a more sensitive speaker compared to DALI Oberon 3, 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.
Oberon 3 can handle a max power of 150 watts RMS from the amp the whereas Borea BR03 has a max power handling value of 100 watts RMS, 50 watts less than the Oberon 3.
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
Oberon 3 features Binding post type posts and Borea BR03 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Oberon 3 has a rear firing port whereas Borea BR03 has a front firing ports. Triangle Borea BR03's front-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Oberon 3 with its rear-firing port.
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 DALI Oberon 3's and Triangle Borea BR03's external dimensions. DALI Oberon 3 has external dimensions of 350.0 x 201.0 x 310.0mm ( 13-3/4 x 7-7/8 x 12-3/16inch) 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 clearly the larger of the two speakers. Its body is 5mm wider, 30mm taller and 4mm deeper than DALI Oberon 3.
Below you can see the front view size comparison of DALI Oberon 3 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 DALI Oberon 3 is approximately 623.1cm2 / 96.6inch2 and base area of the Triangle Borea BR03 is approximately 646.8cm2 / 100.3inch2. The Oberon 3 requires 4% less surface area than the Borea BR03 which gives it a small advantage on placement in tight spaces.
