In this review, we will be comparing Oberon 5 and Borea BR07, two Passive Floor-standing speakers from DALI and Triangle. Let's have a brief look at the main features
of DALI Oberon 5 and Triangle Borea BR07 first before getting into our more
detailed comparison.
What size room are the DALI Oberon 5 and Triangle Borea BR07 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the DALI Oberon 5 and Triangle Borea BR07 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Oberon 5 is a 2-way design whereas the Borea BR07 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 5 features a 1.125" Soft-Dome Tweeter and 2 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2400Hz. On the other hand, the Borea BR07 features a 1" silk Break_in Tweeter , a 6" Midrange and 1 x 6" fiberglass Woofer with a Crossover frequency at 350Hz and 3500Hz.
Frequency Response
Oberon 5 has a frequency range of 39-26k Hz whereas Borea BR07 has a frequency range of 44 - 22k Hz. With a minimum frequency of 39Hz, the Oberon 5 can go significantly deeper on the low side and provide stronger bass compared to the Borea BR07's min frequency of 44Hz.
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.

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 5 is a 6 ohms speaker compared to the Borea BR07 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 5 sensitivity is rated at 88 dB and the Borea BR07's is rated at 91 dB. This 3 dB difference makes the Triangle Borea BR07 a more sensitive speaker compared to DALI Oberon 5, 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 5 can handle a max power of 150 watts RMS from the amp the whereas Borea BR07 has a max power handling value of 120 watts RMS, 30 watts less than the Oberon 5.
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 5 features Binding post type posts and Borea BR07 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Oberon 5 has a rear firing port whereas Borea BR07 has a front firing ports. Triangle Borea BR07's front-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Oberon 5 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 5's and Triangle Borea BR07's external dimensions. DALI Oberon 5 has external dimensions of 832.0 x 202.0 x 277.0mm ( 32-3/4 x 7-15/16 x 10-7/8inch) whereas Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm ( 38.5 x 8.1 x 12.3inch) .
Triangle Borea BR07 is clearly the larger of the two speakers. Its body is 4mm wider, 148mm taller and 37mm deeper than DALI Oberon 5.
Below you can see the front view size comparison of DALI Oberon 5 and Triangle Borea BR07 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 5 is approximately 559.5cm2 / 86.7inch2 and base area of the Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The Oberon 5 requires 13% less surface area than the Borea BR07 which gives it a small advantage on placement in tight spaces.
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 DALI Oberon 5 weighs 10.80kg / 23.8lbs and the Triangle Borea BR07 weighs 16.92kg / 37.2lbs. This makes the Borea BR07 57% heavier than the Oberon 5.
