History
What size room are the Triangle Borea BRS1 and Triangle Borea BR09 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that BRS1 is a 2-way design whereas the Borea BR09 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.

BRS1 features a 1" Silk Soft-Dome Tweeter and 1 x 6.5" Natural cellulose pulp 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
BRS1 has a frequency range of 55-22k Hz whereas Borea BR09 has a frequency range of 35 - 22k Hz. With a minimum frequency of 35Hz, the Borea BR09 can go significantly deeper on the low side and provide stronger bass compared to the BRS1's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Surround class in our database.
Low Frequency
Surround 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
BRS1 and Borea BR09 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BRS1 sensitivity is rated at 89 dB and the Borea BR09's is at 92.5 dB. This 4 dB difference makes the Triangle Borea BR09 a more sensitive speaker compared to Triangle Borea BRS1, hence will play louder with the same amount of watts.
Sensitivity
Surround 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.
Borea BR09 can handle a max power of 170 watts RMS, whereas BRS1 has a max power handling value of 90 watts RMS, 80 watts less than the Borea BR09.
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.
Which plays louder on your 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
BRS1 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
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 BRS1's and Triangle Borea BR09's external dimensions. Triangle Borea BRS1 has external dimensions of 275.0 x 380.0 x 150.0mm (10-13/16 x 14-15/16 x 5-7/8inch) whereas Triangle Borea BR09 has external dimensions of 1095.0 x 206.0 x 314.0mm (43.1 x 8.1 x 12.3inch).
Triangle Borea BRS1 is 820mm shorter and 164mm less deeper than Triangle Borea BR09 but it is also 174mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Triangle Borea BR09 needs about 13% more floor or shelf area. Triangle Borea BR09 is 164mm deeper, so it stands that much further out from the wall. Triangle Borea BR09 is 820mm taller.
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 BRS1 is approximately 570.0cm2 / 88.4inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The BRS1 requires 12% less surface area than the Borea BR09 which gives it a small advantage on placement in tight spaces.
