What size room are the Triangle Borea BR03 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 BR03 Triangle Borea BR04
Near-field Average Poor
Small Room Good Average
Mid-size Room Average Good
Large Room Poor Average
Very Large Room Bad 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.

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.

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 Borea BR03 has a max power handling value of 100 watts RMS, 10 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 BR03's and Triangle Borea BR04's external dimensions. Triangle Borea BR03 has external dimensions of 380.0 x 206.0 x 314.0mm (14.9 x 8.1 x 12.3inch) whereas Triangle Borea BR04 has external dimensions of 425.0 x 220.0 x 314.0mm (16.7 x 8.7 x 12.3inch).

Below you can see the front view size comparison of Triangle Borea BR03 and Triangle Borea BR04 in scale.

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 BR03 is approximately 646.8cm2 / 100.3inch2 and base area of the Triangle Borea BR04 is approximately 690.8cm2 / 107.1inch2. The Borea BR03 requires 6% less surface area than the Borea BR04 which gives it a small advantage on placement in tight spaces.

Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Triangle Borea BR03 weighs 6.26kg / 13.8lbs and the Triangle Borea BR04 weighs 8.64kg / 19lbs. This makes the Borea BR04 38% heavier than the Borea BR03.

Verdict

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

Bassevenly matchedMuch the same reach (46Hz vs 44Hz).

A Triangle Borea BR03  B Triangle Borea BR04
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?

Triangle Borea BR04 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate Triangle Borea BR03 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.
