AK6 features a 1" polyimide diaphragm compression Tractrix horn Tweeter , a 2" Midrange and 1 x 15" fiber-composite with a trihedral exponential folded horn Woofer . On the other hand, the Borea BR09 features a 1" silk dome Tweeter , a 6" Midrange and 3 x 6" fiberglass Woofer with a Crossover frequency at 310Hz and 3900Hz.
Frequency Response
AK6 has a frequency range of 33-20k Hz whereas Borea BR09 has a frequency range of 35 - 22k Hz. With a minimum frequency of 33Hz, the AK6 can go slightly deeper then the Borea BR09's min frequency of 35Hz.
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
AK6 and Borea BR09 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. AK6 sensitivity is rated at 105 dB and the Borea BR09's is at 92.5 dB. This 12 dB difference makes the Klipsch Klipschorn AK6 a more sensitive speaker compared to Triangle Borea BR09, 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.
AK6 can handle a max power of 170 watts RMS from the amp the whereas AK6 has a max power handling value of 100 watts RMS , 70 watts less than the Borea BR09.
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
AK6 features Binding post posts which make bi-amping or bi-wiring possible. Borea BR09 has a Binding post which doesn't 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 Klipsch Klipschorn AK6's and Triangle Borea BR09's external dimensions. Klipsch Klipschorn AK6 has external dimensions of 1347.0 x 794.0 x 718.0mm ( 53 x 31-1/4 x 28-1/4inch) whereas Triangle Borea BR09 has external dimensions of 1095.0 x 206.0 x 314.0mm ( 43.1 x 8.1 x 12.3inch) .
Klipsch Klipschorn AK6 is clearly the larger of the two speakers. Its body is 588mm wider, 252mm taller and 404mm deeper than Triangle Borea BR09.
Below you can see the front view size comparison of Klipsch Klipschorn AK6 and Triangle Borea BR09 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 Klipsch Klipschorn AK6 is approximately 5700.9cm2 / 883.6inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The AK6 requires 781% more surface area than the Borea BR09 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 Klipsch Klipschorn AK6 weighs 100.00kg / 220lbs and the Triangle Borea BR09 weighs 21.80kg / 48lbs. This makes the AK6 359% heavier than the Borea BR09.
Here is a comparison of how AK6 and Borea BR09's weights compare with the average, max and min weights in Passive Floor-standing class.
