Prime Tower features a 1" aluminum dome Tweeter, a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz. 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
Prime Tower has a frequency range of 30-25k Hz whereas Borea BR09 has a frequency range of 35 - 22k Hz. With a minimum frequency of 30Hz, the Prime Tower can go significantly deeper on the low side and provide stronger bass compared to the Borea BR09's min frequency of 35Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Prime Tower and Borea BR09 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Prime Tower sensitivity is rated at 87 dB and the Borea BR09's is at 92.5 dB. This 6 dB difference makes the Triangle Borea BR09 a more sensitive speaker compared to SVS Prime Tower, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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.
Prime Tower can handle a max power of 250 watts RMS, whereas Borea BR09 has a max power handling value of 170 watts RMS, 80 watts less than the Prime Tower.
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
Prime Tower features Binding post type posts and Borea BR09 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Prime Tower has a rear firing port whereas Borea BR09 has a front firing ports. Triangle Borea BR09's front-firing port gives more flexibility in placement in regards to proximity to walls compared to SVS Prime Tower with its rear-firing port.
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 SVS Prime Tower's and Triangle Borea BR09's external dimensions. SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm (36-5/8 x 8 x 11-11/16inch) 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 BR09 is clearly the larger of the two speakers. Its body is 2mm wider, 164mm taller and 17mm deeper than SVS Prime Tower.
Below you can see the front view size comparison of SVS Prime Tower and Triangle Borea BR09 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 SVS Prime Tower is approximately 605.9cm2 / 93.9inch2 and base area of the Triangle Borea BR09 is approximately 646.8cm2 / 100.3inch2. The Prime Tower requires 6% less surface area than the Borea BR09 which gives it a small advantage on placement in tight spaces.
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 SVS Prime Tower weighs 18.23kg / 40.1lbs and the Triangle Borea BR09 weighs 21.80kg / 48lbs. This makes the Borea BR09 20% heavier than the Prime Tower.

A generation apart: Triangle Borea BR09 is the newer design, against a 2015 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | SVS Prime Tower digs deeper - 30Hz against 35Hz. A subwoofer would even that out. |
| Amplifier needs | B | Triangle Borea BR09 is more sensitive (93dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | A | SVS Prime Tower takes more power (250W vs 170W) - more in hand in a big room. |
| Size | depends | SVS Prime Tower is easier to place; Triangle Borea BR09 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. Triangle Borea BR09 sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | A | SVS Prime Tower is cheaper - $1,400 against $1,850, about 24% less. |
A SVS Prime Tower B Triangle Borea BR09
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?
SVS Prime Tower has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 35Hz anyway, so judge these on the other rows instead. Match it to your room: we rate SVS Prime Tower the better fit for a very large room, and Triangle Borea BR09 for a mid-size 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.
