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. On the other hand, the C 97 II features a 1" Tweeter, a 6" Midrange and 3 x 6" Composite Woofer.
Frequency Response
Borea BR07 has a frequency range of 44 - 22k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the Borea BR07's min frequency of 44Hz.
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 BR07 is a 8 ohms speaker compared to the C 97 II which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Borea BR07 sensitivity is rated at 91 dB and the C 97 II's is rated at 89 dB. This 2 dB difference makes the Triangle Borea BR07 a more sensitive speaker compared to Jamo C 97 II, 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.
C 97 II can handle a max power of 180 watts RMS, whereas Borea BR07 has a max power handling value of 120 watts RMS, 60 watts less than the C 97 II.
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
C 97 II features Posts posts which make bi-amping or bi-wiring possible. Borea BR07 has a Binding post which doesn't feature bi-amping/bi-wiring.

Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Borea BR07 has a front firing port whereas C 97 II has a rear firing ports. Triangle Borea BR07's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Jamo C 97 II with its rear-firing port.
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 BR07's and Jamo C 97 II's external dimensions. Triangle Borea BR07 has external dimensions of 980.0 x 206.0 x 314.0mm (38.5 x 8.1 x 12.3inch) whereas Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm (42-1/8 x 9-3/4 x 15-13/16inch).
Jamo C 97 II is clearly the larger of the two speakers. Its body is 42mm wider, 90mm taller and 88mm deeper than Triangle Borea BR07.
Below you can see the front view size comparison of Triangle Borea BR07 and Jamo C 97 II 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 BR07 is approximately 646.8cm2 / 100.3inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Borea BR07 requires 35% less surface area than the C 97 II 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 Triangle Borea BR07 weighs 16.92kg / 37.2lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 45% heavier than the Borea BR07.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass |
B |
Jamo C 97 II digs deeper - 32Hz against 44Hz. |
| Amplifier needs |
A |
Triangle Borea BR07 is more sensitive (91dB vs 89dB), so it goes louder on the same amplifier. |
| Amplifier match |
A |
Triangle Borea BR07 is the easier load at 8 ohms. |
| Headroom |
B |
Jamo C 97 II takes more power (180W vs 120W) - more in hand in a big room. |
| Size |
depends |
Triangle Borea BR07 is easier to place; Jamo C 97 II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
depends |
Jamo C 97 II: bi-amping. Triangle Borea BR07 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price |
A |
Triangle Borea BR07 is cheaper - $1,200 against $1,378, about 13% less. |
A Triangle Borea BR07
B Jamo C 97 II
depends neither is better in the abstract - it turns on your room, placement 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 44Hz anyway, which makes the cheaper Triangle Borea BR07 much easier to justify. In a large or open-plan room, Jamo C 97 II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Triangle Borea BR07 is the easier speaker to get right.
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.
