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 BR07 can handle a max power of 180 watts RMS from the amp the whereas Borea BR07 has a max power handling value of 120 watts RMS , 60 watts less than the C 97 II.
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
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
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 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.
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.
