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
Dymension DM60 is a 4 ohms speaker compared to the Borea BR09 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Dymension DM60 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM60 sensitivity is rated at 88 dB and the Borea BR09's is rated at 92.5 dB. This 5 dB difference makes the Triangle Borea BR09 a more sensitive speaker compared to Definitive Dymension DM60, 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.
Dymension DM60 can handle a max power of 300 watts RMS from the amp the whereas Borea BR09 has a max power handling value of 170 watts RMS, 130 watts less than the Dymension DM60.
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
Dymension DM60 features Binding post type posts and Borea BR09 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 Definitive Dymension DM60's and Triangle Borea BR09's external dimensions. Definitive Dymension DM60 has external dimensions of 1153 x 287 x 349 mm ( 45.4 x 11.3 x 13.7 in) whereas Triangle Borea BR09 has external dimensions of 1095.0 x 206.0 x 314.0mm ( 43.1 x 8.1 x 12.3inch) .
Definitive Dymension DM60 is clearly the larger of the two speakers. Its body is 81mm wider, 58mm taller and 35mm deeper than Triangle Borea BR09.
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 Definitive Dymension DM60 is approximately 1001.6cm2 / 155.2inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The Dymension DM60 requires 55% more surface area than the Borea BR09 which gives it a small disadvantage on placement in tight spaces.
