In this review, we will be comparing Concord and Borea BR07, two Passive Floor-standing speakers from KLH and Triangle. Let's have a brief look at the main features
of KLH Concord and Triangle Borea BR07 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the KLH Concord 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 Concord 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.

Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer . 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
Concord has a frequency range of 28-23k Hz whereas Borea BR07 has a frequency range of 44 - 22k Hz. With a minimum frequency of 28Hz, the Concord 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
Concord and Borea BR07 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Concord sensitivity is rated at 94 dB and the Borea BR07's is at 91 dB. This 3 dB difference makes the KLH Concord a more sensitive speaker compared to Triangle Borea BR07, 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.
Concord can handle a max power of 120 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS , 120 watts less than the Borea BR07.
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
Concord features Binding post type posts and Borea BR07 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

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 KLH Concord's and Triangle Borea BR07's external dimensions. KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm ( 40-3/8 x 8-5/16 x 14-15/16inch) whereas Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm ( 38.5 x 8.1 x 12.3inch) .
KLH Concord is clearly the larger of the two speakers. Its body is 6mm wider, 46mm taller and 66mm deeper than Triangle Borea BR07.
Below you can see the front view size comparison of KLH Concord 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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the Triangle Borea BR07 is approximately 646.8cm2 / 100.3inch2. The Concord requires 25% 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 KLH Concord weighs 20.45kg / 45lbs and the Triangle Borea BR07 weighs 16.92kg / 37.2lbs. This makes the Concord 21% heavier than the Borea BR07.
Here is a comparison of how Concord and Borea BR07's weights compare with the average, max and min weights in Passive Floor-standing class.
