In this review, we will be comparing Diamond 12.3 and Borea BR07, two Passive Floor-standing speakers from Wharfedale and Triangle. Let's have a brief look at the main features
of Wharfedale Diamond 12.3 and Triangle Borea BR07 first before getting into our more
detailed comparison.
What size room are the Wharfedale Diamond 12.3 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 Wharfedale Diamond 12.3 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 Diamond 12.3 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.

Diamond 12.3 features a 1" Textile Soft-Dome Tweeter and 2 x 5" Mica-infused polypropylene Woofer with a Crossover frequency at 2200Hz. 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
Diamond 12.3 has a frequency range of 45-20k Hz whereas Borea BR07 has a frequency range of 44 - 22k Hz. With a minimum frequency of 44Hz, the Borea BR07 can go slightly deeper then the Diamond 12.3's min frequency of 45Hz.
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
Diamond 12.3 and Borea BR07 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 12.3 sensitivity is rated at 88 dB and the Borea BR07's is at 91 dB. This 3 dB difference makes the Triangle Borea BR07 a more sensitive speaker compared to Wharfedale Diamond 12.3, 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.
Diamond 12.3 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 Diamond 12.3.
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
Diamond 12.3 features Binding post posts which make bi-amping or bi-wiring possible. Borea BR07 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Diamond 12.3 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 Wharfedale Diamond 12.3 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 Wharfedale Diamond 12.3's and Triangle Borea BR07's external dimensions. Wharfedale Diamond 12.3 has external dimensions of 985.0 x 180.0 x 362.0mm ( 38-3/4 x 7-1/8 x 14-1/4inch) 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 5mm shorter and 48mm less deeper than Wharfedale Diamond 12.3 but it is also 26mm wider.

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 Wharfedale Diamond 12.3 is approximately 651.6cm2 / 101.0inch2 and base area of the Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The Diamond 12.3 requires 1% more surface area than the Borea BR07 which gives it a small disadvantage 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 Wharfedale Diamond 12.3 weighs 19.50kg / 42.9lbs and the Triangle Borea BR07 weighs 16.92kg / 37.2lbs. This makes the Diamond 12.3 15% heavier than the Borea BR07.
