History
What size room are the Triangle Borea BRS1 and Triangle Borea BRA1 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.)
In the following sections, we will get into more detail in order to better understand how the Triangle Borea BRS1 and Triangle Borea BRA1 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

BRS1 features a 1" Silk Soft-Dome Tweeter and 1 x 6.5" Natural cellulose pulp Woofer . On the other hand, the BRA1 features a 1" Silk Soft-Dome Tweeter and 1 x 6.5" Natural cellulose pulp Woofer .
Frequency Response
BRS1 has a frequency range of 55-22k Hz whereas BRA1 has a frequency range of 90-22k Hz. With a minimum frequency of 55Hz, the BRS1 can go significantly deeper on the low side and provide stronger bass compared to the BRA1's min frequency of 90Hz.
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 Surround class in our database.

High Frequency
Surround Speakers
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
BRS1 and BRA1 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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.
BRS1 can handle a max power of 90 watts RMS from the amp the whereas BRA1 has a max power handling value of 80 watts RMS, 10 watts less than the BRS1.
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
BRS1 features Binding post type posts and BRA1 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 Triangle Borea BRS1's and Triangle Borea BRA1'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 BRA1 has external dimensions of 180.0 x 206.0 x 300.0mm ( 7-1/16 x 8-1/8 x 11-13/16inch) .
Triangle Borea BRA1 is 174mm narrower and 95mm shorter than Triangle Borea BRS1 but it is also 150mm deeper.
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 BRA1 is approximately 618.0cm2 / 95.8inch2. The BRS1 requires 8% less surface area than the BRA1 which gives it a small advantage on placement in tight spaces.
