In this review, we will be comparing Dynamo 10 and SuperSub X, two Powered Subwoofer speakers from MartinLogan and GoldenEar. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of MartinLogan Dynamo 10 and GoldenEar SuperSub X first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.MartinLogan Dynamo 10 and GoldenEar SuperSub X have a totally different setup: the MartinLogan Dynamo 10 features 1 x 10-inch drivers whereas the SuperSub X features 2 x 8-inch drivers.
Frequency Response
Dynamo 10 has a frequency range of 23-200 Hz whereas SuperSub X has a frequency range of 12-250 Hz. With a minimum frequency of 12Hz, the SuperSub X can go significantly deeper on the low side and provide stronger bass compared to the Dynamo 10's min frequency of 23Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

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 MartinLogan Dynamo 10's and GoldenEar SuperSub X's external dimensions. MartinLogan Dynamo 10 has external dimensions of 373.1 x 349.3 x 404.8mm () whereas GoldenEar SuperSub X has external dimensions of 324.0 x 356.0 x 388.0mm (12-3/4inch x 14inch x 15-1/4inch).
GoldenEar SuperSub X is 49.1mm shorter and 16.8mm less deeper than MartinLogan Dynamo 10 but it is also 6.7mm wider.
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.
Near-identical footprints. MartinLogan Dynamo 10 is 17mm deeper, so it stands that much further out from the wall. MartinLogan Dynamo 10 is 49mm 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 MartinLogan Dynamo 10 is approximately 1414.0cm2 / 219.2inch2 and base area of the GoldenEar SuperSub X is approximately 1381.3cm2 / 214.1inch2. The Dynamo 10 requires 2% more surface area than the SuperSub X which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The MartinLogan Dynamo 10 weighs 19.41kg / 42.7lbs and the GoldenEar SuperSub X weighs 18.18kg / 40lbs. This makes the Dynamo 10 7% heavier than the SuperSub X.
Here is a comparison of how Dynamo 10 and SuperSub X's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed subwoofer against a passive radiator one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | B | GoldenEar SuperSub X goes deeper - 12Hz against 23Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | GoldenEar SuperSub X has the bigger amplifier - 1400W against 500W RMS, about 4.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | GoldenEar SuperSub X moves more air: 2 x 8" against 10" is 1.28x the cone area, not the 1.13x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | MartinLogan Dynamo 10 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; GoldenEar SuperSub X is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Price | A | MartinLogan Dynamo 10 costs less - $1,200 against $1,499, about 20% less. |
A MartinLogan Dynamo 10 B GoldenEar SuperSub X
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 subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
GoldenEar SuperSub X leads across most of the measured areas for a modest premium, so it is the easier pick if the budget stretches. MartinLogan Dynamo 10 is the one to take if it does not. Films or music? If this is mainly a home cinema, GoldenEar SuperSub X will hit harder for the money; if it is mainly for music in a normal-sized room, MartinLogan Dynamo 10 is usually the easier one to make sound right.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
