Drivers

One of the fundamental differences between these two speakers is that Dymension DM40 is a 2-way design whereas the Borea BR07 is a 3-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.

Driver Definitive Dymension DM40 Triangle Borea BR07
Driver Setup 2-way 3-way
Tweeter 1-inch 1-inch
Midrange - 1 x 6-inch
Woofer 4 x 4.5-inch 1 x 6-inch

Dymension DM40 features a 1" aluminum oxide 2 x Hard-Dome Tweeter and 4 x 4.5" Polypropelene Woofer . On the other hand, the 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.

Frequency Response

Dymension DM40 has a frequency range of 55-23 kHz whereas Borea BR07 has a frequency range of 44 - 22k Hz. With a minimum frequency of 44Hz, the Borea BR07 can go significantly deeper on the low side and provide stronger bass compared to the Dymension DM40's min frequency of 55Hz.

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

Dymension DM40 is a 4 ohms speaker compared to the Borea BR07 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 DM40 can provide this impedance level.

These two speakers also have different sensitivity levels. Dymension DM40 sensitivity is rated at 87 dB and the Borea BR07's is rated at 91 dB. This 4 dB difference makes the Triangle Borea BR07 a more sensitive speaker compared to Definitive Dymension DM40, 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 DM40 can handle a max power of 250 watts RMS from the amp the whereas Borea BR07 has a max power handling value of 120 watts RMS, 130 watts less than the Dymension DM40.

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 DM40 features Binding post type posts and Borea BR07 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
