M30.3 XD2 features a 1" Ferrofluid-cooled dome Dome Tweeter and 1 x 8" RADIAL Woofer. On the other hand, the Evoke 30 features a 1.1" Cerotar with Hexis Tweeter and 1 x 7" Magnesium Silicate Polymer Woofer with a Crossover frequency at 3200Hz.
Frequency Response
M30.3 XD2 has a frequency range of 50-20k Hz whereas Evoke 30 has a frequency range of 40-23k Hz. With a minimum frequency of 40Hz, the Evoke 30 can go significantly deeper on the low side and provide stronger bass compared to the M30.3 XD2's min frequency of 50Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
M30.3 XD2 and Evoke 30 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. M30.3 XD2 sensitivity is rated at 85 dB and the Evoke 30's is at 86 dB. This 1 dB difference makes the Dynaudio Evoke 20 a more sensitive speaker compared to Harbeth M30.3 XD2, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Evoke 30 can handle a max power of 180 watts RMS, whereas M30.3 XD2 has a max power handling value of 150 watts RMS, 30 watts less than the Evoke 30.
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
M30.3 XD2 features Binding post type posts and Evoke 30 has a Binding 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 Harbeth M30.3 XD2's and Dynaudio Evoke 20's external dimensions. Harbeth M30.3 XD2 has external dimensions of 460.0 x 277.0 x 275.0mm (18-1/8 x 10-7/8 x 10-13/16inch) whereas Dynaudio Evoke 20 has external dimensions of 380.0 x 215.0 x 343.0mm (15 x 8.5 x 12.1inch).
Dynaudio Evoke 20 is 62mm narrower and 80mm shorter than Harbeth M30.3 XD2 but it is also 68mm 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 Harbeth M30.3 XD2 is approximately 761.8cm2 / 118.1inch2 and base area of the Dynaudio Evoke 20 is approximately 737.5cm2 / 114.3inch2. The M30.3 XD2 requires 3% more surface area than the Evoke 30 which gives it a small disadvantage 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 Harbeth M30.3 XD2 weighs 11.60kg / 25.5lbs and the Dynaudio Evoke 20 weighs 9.90kg / 21.8lbs. This makes the M30.3 XD2 17% heavier than the Evoke 30.
Here is a comparison of how M30.3 XD2 and Evoke 30's weights compare with the average, max and min weights in Passive Bookshelf class.

A generation apart: Harbeth M30.3 XD2 is the newer design, against a 2019 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 |
Dynaudio Evoke 20 digs deeper - 40Hz against 50Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (85dB vs 86dB) - both want much the same power. |
| Headroom |
evenly matched |
Similar power handling (150W vs 180W). |
| Size |
depends |
Dynaudio Evoke 20 is easier to place; Harbeth M30.3 XD2 is bigger, which usually goes with fuller bass. Your room decides. |
| Price |
B |
Dynaudio Evoke 20 is cheaper - $4,798 against $6,290, about 24% less. |
A Harbeth M30.3 XD2
B Dynaudio Evoke 20
depends neither is better in the abstract - it turns on your room, placement 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?
Dynaudio Evoke 20 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 50Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Harbeth M30.3 XD2 the better fit for near-field listening and a small room, and Dynaudio Evoke 20 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.
