What size room are the Definitive Demand D15 and GoldenEar Triton Seven 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:

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
One of the fundamental differences between these two speakers is that Demand D15 is a 3-way design whereas the Triton Seven is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Demand D15 features a 1" aluminum dome Tweeter, a 5.25" Midrange and 2 x 5.25" Carbon-fiber Woofer. On the other hand, the Triton Seven features a " Folded Ribbon Tweeter and 2 x 5.25" Polypropylene Woofer.
Frequency Response
Demand D15 has a frequency range of 48-22k Hz whereas Triton Seven has a frequency range of 29-35k Hz. With a minimum frequency of 29Hz, the Triton Seven can go significantly deeper on the low side and provide stronger bass compared to the Demand D15's min frequency of 48Hz.
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
Demand D15 and Triton Seven have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Demand D15 sensitivity is rated at 85.5 dB and the Triton Seven's is at 89 dB. This 3 dB difference makes the GoldenEar Triton Seven a more sensitive speaker compared to Definitive Demand D15, 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.
Both handle the same maximum of 300 watts RMS, though Demand D15 is rated 30-300 watts and Triton Seven 10-300 watts.
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
Demand D15 features 5-Way post posts which make bi-amping or bi-wiring possible. Triton Seven has a 5-way Post which doesn't feature bi-amping/bi-wiring.
Definitive Demand D15's 5-Way post terminals allows Bi-amping or bi-wiring
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 Definitive Demand D15's and GoldenEar Triton Seven's external dimensions. Definitive Demand D15 has external dimensions of 1023.0 x 231.0 x 324.0mm (40-1/4 x 9-1/16 x 12-3/4inch) whereas GoldenEar Triton Seven has external dimensions of 1029.0 x 267.0 x 369.0mm (40-1/2 x 10-1/2 x 14-1/2inch).
GoldenEar Triton Seven is clearly the larger of the two speakers. Its body is 36mm wider, 6mm taller and 45mm deeper than Definitive Demand D15.
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 Definitive Demand D15 is approximately 748.4cm2 / 116.0inch2 and base area of the GoldenEar Triton Seven is approximately 985.2cm2 / 152.7inch2. The Demand D15 requires 24% less surface area than the Triton Seven 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 Definitive Demand D15 weighs 23.60kg / 51.9lbs and the GoldenEar Triton Seven weighs 14.55kg / 32lbs. This makes the Demand D15 62% heavier than the Triton Seven.
Here is a comparison of how Demand D15 and Triton Seven's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Definitive Demand D15 is the newer design, against a 2013 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | GoldenEar Triton Seven digs deeper - 29Hz against 48Hz. |
| Amplifier needs | B | GoldenEar Triton Seven is more sensitive (89dB vs 86dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | Definitive Demand D15 is easier to place; GoldenEar Triton Seven is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | Definitive Demand D15: bi-amping. |
| Price | B | GoldenEar Triton Seven is cheaper - $1,798 against $2,798, about 36% less. |
A Definitive Demand D15 B GoldenEar Triton Seven
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?
GoldenEar Triton Seven 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 48Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, GoldenEar Triton Seven is the safer partner - the other will want more current or more watts to sound its best.
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.
