What size room are the Definitive Dymension DM70 and GoldenEar Triton Five 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 Dymension DM70 is a 3-way design whereas the Triton Five 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.

Dymension DM70 features a 1" aluminum oxide 2 x Hard-Dome Tweeter, a 5.25" Midrange and 1 x 10" Polypropelene Woofer. On the other hand, the Triton Five features a " Folded Ribbon Tweeter and 2 x 6" Polypropylene Woofer.
Frequency Response
Dymension DM70 has a frequency range of 30-23 kHz whereas Triton Five has a frequency range of 26-35k Hz. With a minimum frequency of 26Hz, the Triton Five can go slightly deeper then the Dymension DM70's min frequency of 30Hz.
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
Dymension DM70 is a 4 ohms speaker compared to the Triton Five which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Dymension DM70 can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.
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.
Triton Five can handle a max power of 400 watts RMS, whereas Dymension DM70 has a max power handling value of 300 watts RMS, 100 watts less than the Triton Five.
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.

Input Type and Bi-Amping / Bi-Wiring
Dymension DM70 features 5-way Post type posts and Triton Five has a 5-way Post type posts. None of these speakers feature bi-amping/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 Dymension DM70's and GoldenEar Triton Five's external dimensions. Definitive Dymension DM70 has external dimensions of 1204 x 287 x 407 mm (47.4 x 11.3 x 16.0 in) whereas GoldenEar Triton Five has external dimensions of 1131.0 x 281.0 x 421.0mm (44-1/2 x 11-1/16 x 16-9/16inch).
GoldenEar Triton Five is 6mm narrower and 73mm shorter than Definitive Dymension DM70 but it is also 14mm deeper.
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 Dymension DM70 is approximately 1168.1cm2 / 181.1inch2 and base area of the GoldenEar Triton Five is approximately 1183.0cm2 / 183.4inch2. The Dymension DM70 requires 1% less surface area than the Triton Five 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 Dymension DM70 weighs 33.60kg / 73.9lbs and the GoldenEar Triton Five weighs 18.18kg / 40lbs. This makes the Dymension DM70 85% heavier than the Triton Five.

These sit in different price classes - Definitive Dymension DM70 costs roughly 1.7x what GoldenEar Triton Five does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | GoldenEar Triton Five digs deeper - 26Hz against 30Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (90dB vs 90dB) - both want much the same power. |
| Amplifier match | B | GoldenEar Triton Five is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | GoldenEar Triton Five takes more power (400W vs 300W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Definitive Dymension DM70: Atmos drivers. |
| Price | B | GoldenEar Triton Five is cheaper - $2,398 against $3,998, about 40% less; arguably a different class. |
A Definitive Dymension DM70 B GoldenEar Triton Five
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 Five is the easier recommendation: it leads on most of the measured areas and costs less. Take Definitive Dymension DM70 if its size, looks or fit in your room suit you better. If your amplifier is modest, vintage or valve-based, GoldenEar Triton Five is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $1,600 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.
