Drivers
One of the fundamental differences between these two speakers is that Oberon 7 is a 2-way design whereas the Borea BR09 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.

Oberon 7 features a 1.125" Soft-Dome Tweeter and 2 x 7" Wood Fiber Woofer with a Crossover frequency at 2300Hz. On the other hand, the Borea BR09 features a 1" silk dome Tweeter , a 6" Midrange and 3 x 6" fiberglass Woofer with a Crossover frequency at 310Hz and 3900Hz.
Frequency Response
Oberon 7 has a frequency range of 36-26k Hz whereas Borea BR09 has a frequency range of 35 - 22k Hz. With a minimum frequency of 35Hz, the Borea BR09 can go slightly deeper then the Oberon 7's min frequency of 36Hz.
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
Oberon 7 is a 6 ohms speaker compared to the Borea BR09 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 7 sensitivity is rated at 88.5 dB and the Borea BR09's is rated at 92.5 dB. This 4 dB difference makes the Triangle Borea BR09 a more sensitive speaker compared to DALI Oberon 7, 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 7 can handle a max power of 180 watts RMS from the amp the whereas Borea BR09 has a max power handling value of 170 watts RMS, 10 watts less than the Oberon 7.
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 7 features Binding post type posts and Borea BR09 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Oberon 7 has a rear firing port whereas Borea BR09 has a front firing ports. Triangle Borea BR09's front-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Oberon 7 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 7's and Triangle Borea BR09's external dimensions. DALI Oberon 7 has external dimensions of 1016.0 x 200.0 x 329.0mm ( 40 x 7-7/8 x 12-15/16inch) whereas Triangle Borea BR09 has external dimensions of 1095.0 x 206.0 x 314.0mm ( 43.1 x 8.1 x 12.3inch) .
DALI Oberon 7 is 6mm narrower and 79mm shorter than Triangle Borea BR09 but it is also 15mm deeper.
Below you can see the front view size comparison of DALI Oberon 7 and Triangle Borea BR09 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 7 is approximately 658.0cm2 / 102.0inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The Oberon 7 requires 2% more surface area than the Borea BR09 which gives it a small disadvantage on placement in tight spaces.
