In this review, we will be comparing Dynamo 10 and Dynamo 1100X, two Powered Subwoofer speakers by MartinLogan. 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 MartinLogan 1100X 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.Both MartinLogan Dynamo 10and MartinLogan 1100X have a single woofer setup however the MartinLogan Dynamo 10's woofer is 10-inch whereas the MartinLogan 1100X features a 12-inch woofer.
Frequency Response
Dynamo 10 has a frequency range of 23-200 Hz whereas Dynamo 1100X has a frequency range of 22-200 Hz. With a minimum frequency of 22Hz, the Dynamo 1100X can go slightly deeper then 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 MartinLogan 1100X's external dimensions. MartinLogan Dynamo 10 has external dimensions of 373.1 x 349.3 x 404.8mm () whereas MartinLogan 1100X has external dimensions of 435.0 x 381.0 x 410.0mm (17-1/8 x 15 x 16-1/8inch).
MartinLogan 1100X is clearly the larger of the two speakers. Its body is 31.7mm wider, 61.9mm taller and 5.2mm deeper than MartinLogan Dynamo 10.
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.
MartinLogan 1100X needs about 10% more floor or shelf area. MartinLogan 1100X is 62mm 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 MartinLogan 1100X is approximately 1562.1cm2 / 242.1inch2. The Dynamo 10 requires 9% less surface area than the Dynamo 1100X which gives it a small advantage 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 MartinLogan 1100X weighs 20.91kg / 46lbs. This makes the Dynamo 1100X 8% heavier than the Dynamo 10.
Here is a comparison of how Dynamo 10 and Dynamo 1100X's weights compare with the average, max and min weights in Powered Subwoofer class.

Both are MartinLogan, so the design approach is shared and the differences are mostly in output, size and price.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (23Hz vs 22Hz). |
| Amplifier power | B | MartinLogan 1100X has the bigger amplifier - 650W against 500W RMS, about 1.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | MartinLogan 1100X moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | MartinLogan Dynamo 10 is about 22% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | A | MartinLogan Dynamo 10 costs less - $1,200 against $1,500, about 20% less. |
A MartinLogan Dynamo 10 B MartinLogan 1100X
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?
The usual trade-off: MartinLogan 1100X measures better, MartinLogan Dynamo 10 costs about 20% less. In a normal room, placement will make a bigger difference than the gap between these two.
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.
