Borea BR03 features a 1" silk Tweeter and 1 x 6" fiberglass Woofer with a Crossover frequency at 3600Hz. On the other hand, the Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Borea BR03 has a frequency range of 46 - 22k Hz whereas Diamond 225 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go slightly deeper then the Borea BR03's min frequency of 46Hz.
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 Bookshelf class in our database.

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
Borea BR03 and Diamond 225 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Borea BR03 sensitivity is rated at 90 dB and the Diamond 225's is at 87 dB. This 3 dB difference makes the Triangle Borea BR03 a more sensitive speaker compared to Wharfedale 225, 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.
Borea BR03 can handle a max power of 120 watts RMS from the amp the whereas Borea BR03 has a max power handling value of 100 watts RMS , 20 watts less than the Diamond 225.
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
Diamond 225 features Post posts which make bi-amping or bi-wiring possible. Borea BR03 has a Binding post which doesn't feature bi-amping/bi-wiring.

Wharfedale 225's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Borea BR03 has a front firing port whereas Diamond 225 has a bottom firing ports. Triangle Borea BR03's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale 225 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 Triangle Borea BR03's and Wharfedale 225's external dimensions. Triangle Borea BR03 has external dimensions of 380.0 x 206.0 x 314.0mm ( 14.9 x 8.1 x 12.3inch) whereas Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) .
Triangle Borea BR03 is clearly the larger of the two speakers. Its body is 10mm wider, 25mm taller and 24mm deeper than Wharfedale 225.
Below you can see the front view size comparison of Triangle Borea BR03 and Wharfedale 225 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 BR03 is approximately 646.8cm2 / 100.3inch2 and base area of the Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The Borea BR03 requires 14% more surface area than the Diamond 225 which gives it a small disadvantage on placement in tight spaces.
