What size room are the Triangle Esprit Voce Ez and Triangle Solstice C3 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:

Voce Ez features a 1" Titanium dome Horn-Loaded Tweeter and 2 x 5" Fibreglass Woofer with a Crossover frequency at 3300Hz. On the other hand, the Solstice C3 features a 1" Magnesium alloy dome Horn-Loaded Tweeter and 2 x 6.5" Natural cellulose pulp Woofer with a Crossover frequency at 2850Hz.
Frequency Response
Voce Ez has a frequency range of 60-22k Hz whereas Solstice C3 has a frequency range of 50-22k Hz. With a minimum frequency of 50Hz, the Solstice C3 can go significantly deeper on the low side and provide stronger bass compared to the Voce Ez's min frequency of 60Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
Voce Ez and Solstice C3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Voce Ez sensitivity is rated at 91 dB and the Solstice C3's is at 92 dB. This 1 dB difference makes the Triangle Solstice C3 a more sensitive speaker compared to Triangle Esprit Voce Ez, hence will play louder with the same amount of watts.
Sensitivity
Center Channel 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.
Solstice C3 can handle a max power of 120 watts RMS, whereas Voce Ez has a max power handling value of 60 watts RMS, 60 watts less than the Solstice C3.
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.

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 Esprit Voce Ez's and Triangle Solstice C3's external dimensions. Triangle Esprit Voce Ez has external dimensions of 168.0 x 510.0 x 290.0mm (6-5/8 x 20-1/16 x 11-7/16inch) whereas Triangle Solstice C3 has external dimensions of 205.0 x 540.0 x 305.0mm (8-1/16 x 21-1/4 x 12inch).
Triangle Solstice C3 is clearly the larger of the two speakers. Its body is 30mm wider, 37mm taller and 15mm deeper than Triangle Esprit Voce Ez.
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 Solstice C3 needs about 11% more floor or shelf area. Triangle Solstice C3 is 15mm deeper, so it stands that much further out from the wall. Triangle Solstice C3 is 37mm 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 Esprit Voce Ez is approximately 1479.0cm2 / 229.2inch2 and base area of the Triangle Solstice C3 is approximately 1647.0cm2 / 255.3inch2. The Voce Ez requires 10% less surface area than the Solstice C3 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 Triangle Esprit Voce Ez weighs 9.50kg / 20.9lbs and the Triangle Solstice C3 weighs 11.75kg / 25.9lbs. This makes the Solstice C3 24% heavier than the Voce Ez.
Here is a comparison of how Voce Ez and Solstice C3's weights compare with the average, max and min weights in Passive Center Channel class.

Both are Triangle, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | B | Triangle Solstice C3 digs deeper - 50Hz against 60Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (91dB vs 92dB) - both want much the same power. |
| Headroom | B | Triangle Solstice C3 takes more power (120W vs 60W) - more in hand in a big room. |
| Size | depends | Triangle Esprit Voce Ez is easier to place; Triangle Solstice C3 is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | A | Triangle Esprit Voce Ez: bi-amping. Triangle Esprit Voce Ez sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | A | Triangle Esprit Voce Ez is cheaper - $525 against $749, about 30% less. |
A Triangle Esprit Voce Ez B Triangle Solstice C3
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 Solstice C3 is ahead, but only on 1 of the measured areas, and it costs about 43% more. That is a lot of money for a narrow margin on paper - Triangle Esprit Voce Ez looks like the sensible buy unless something else about the Triangle Solstice C3 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, which makes the cheaper Triangle Esprit Voce Ez much easier to justify. Think about the whole system, not just the speakers: the roughly $224 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
