What size room are the Triangle Borea BRS1 and Triangle Borea BR04 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:

Listening Environment* Triangle Borea BRS1 Triangle Borea BR04
Near-field Good Poor
Small Room Good Average
Mid-size Room Average Good
Large Room Poor Average
Very Large Room No way Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 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

Both BRS1 and Borea BR04 are 2-way speakers.

Woofer 1 x 6.5-inch 1 x 6-inch

BRS1 features a 1" Silk Soft-Dome Tweeter and 1 x 6.5" Natural cellulose pulp Woofer. On the other hand, the Borea BR04 features a 1" silk Dome Tweeter and 1 x 6" Paper Cone Woofer with a Crossover frequency at 3200Hz.

Frequency Response

BRS1 has a frequency range of 55-22k Hz whereas Borea BR04 has a frequency range of 44 - 22k Hz. With a minimum frequency of 44Hz, the Borea BR04 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.

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 BR04 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 BR04's is at 90 dB. This 1 dB difference makes the Triangle Borea BR04 a more sensitive speaker compared to Triangle Borea BRS1, 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. Staying within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.

Borea BR04 can handle a max power of 110 watts RMS, whereas BRS1 has a max power handling value of 90 watts RMS, 20 watts less than the Borea BR04.

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.

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 BR04'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 BR04 has external dimensions of 425.0 x 220.0 x 314.0mm (16.7 x 8.7 x 12.3inch).

Triangle Borea BRS1 is 150mm shorter and 164mm less deeper than Triangle Borea BR04 but it is also 160mm wider.

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 BR04 needs about 21% more floor or shelf area. Triangle Borea BR04 is 164mm deeper, so it stands that much further out from the wall. Triangle Borea BR04 is 150mm 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 BR04 is approximately 690.8cm2 / 107.1inch2. The BRS1 requires 17% less surface area than the Borea BR04 which gives it a small advantage on placement in tight spaces.

Verdict

Siblings in Triangle's Borea series, so they share a family sound. It comes down to size, output and price.

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

The usual trade-off: Triangle Borea BR04 measures better, Triangle Borea BRS1 costs about about 13% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, which makes the cheaper Triangle Borea BRS1 much easier to justify. Match it to your room: we rate Triangle Borea BRS1 the better fit for near-field listening and a small room, and Triangle Borea BR04 for a mid-size room and a large room.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
