The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Borea BR10 is a 3-way design whereas the Concord is a 2-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.

Borea BR10 features a 1" silk dome Tweeter, a 6" Midrange and 2 x 8" fiberglass Woofer with a Crossover frequency at 310Hz and 3900Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
Borea BR10 has a frequency range of 30 - 22k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the Borea BR10's min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Borea BR10 and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Borea BR10 sensitivity is rated at 92 dB and the Concord's is at 94 dB. This 2 dB difference makes the KLH Concord a more sensitive speaker compared to Triangle Borea BR10, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Concord can handle a max power of 225 watts RMS, whereas Borea BR10 has a max power handling value of 200 watts RMS, 25 watts less than the Concord.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Borea BR10 features 5-Way post type posts and Concord has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 BR10's and KLH Concord's external dimensions. Triangle Borea BR10 has external dimensions of 1110 x 245 x 380mm (43.7 x 9.6 x 15inch) whereas 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).
KLH Concord is 33mm narrower and 84mm shorter than Triangle Borea BR10 but they have the same thickness of 380.0mm.

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 BR10 is approximately 931.0cm2 / 144.3inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Borea BR10 requires 16% more surface area than the Concord 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 Triangle Borea BR10 weighs 29.55kg / 65lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Borea BR10 44% heavier than the Concord.

These sit in different price classes - Triangle Borea BR10 costs roughly 2.3x what KLH Concord does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (30Hz vs 28Hz). |
| Amplifier needs | B | KLH Concord is more sensitive (94dB vs 92dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (200W vs 225W). |
| Size | depends | KLH Concord is easier to place; Triangle Borea BR10 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | KLH Concord is cheaper - $1,000 against $2,299, about 57% less; arguably a different class. |
A Triangle Borea BR10 B KLH Concord
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KLH Concord has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If your amplifier is modest, vintage or valve-based, KLH Concord is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $1,299 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
