In this review, we will be comparing Dynamo 1100X and Dynamo 800X, 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 1100X and MartinLogan 800X 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 1100Xand MartinLogan 800X have a single woofer setup however the MartinLogan 1100X's woofer is 12-inch whereas the MartinLogan 800X features a 10-inch woofer.
Frequency Response
Dynamo 1100X has a frequency range of 22-200 Hz whereas Dynamo 800X has a frequency range of 24-200 Hz. With a minimum frequency of 22Hz, the Dynamo 1100X can go slightly deeper then the Dynamo 800X's min frequency of 24Hz.
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.

Cabinet Type
Both MartinLogan 1100X and MartinLogan 800X have Acoustic Suspension type cabinets. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
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 1100X's and MartinLogan 800X's external dimensions. MartinLogan 1100X has external dimensions of 435.0 x 381.0 x 410.0mm (17-1/8 x 15 x 16-1/8inch) whereas MartinLogan 800X has external dimensions of 351.0 x 318.0 x 350.0mm (13-13/16 x 12-1/2 x 13-3/4inch).
MartinLogan 1100X is clearly the larger of the two speakers. Its body is 63mm wider, 84mm taller and 60mm deeper than MartinLogan 800X.
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 1100X is approximately 1562.1cm2 / 242.1inch2 and base area of the MartinLogan 800X is approximately 1113.0cm2 / 172.5inch2. The Dynamo 1100X requires 40% more surface area than the Dynamo 800X 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 1100X weighs 20.91kg / 46lbs and the MartinLogan 800X weighs 13.64kg / 30lbs. This makes the Dynamo 1100X 53% heavier than the Dynamo 800X.
Here is a comparison of how Dynamo 1100X and Dynamo 800X's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers 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 floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
MartinLogan 1100X needs about 40% more floor area. MartinLogan 1100X stands 60mm further into the room. MartinLogan 1100X is 84mm taller.

Siblings in MartinLogan's Dynamo range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (22Hz vs 24Hz). |
| Amplifier power | A | MartinLogan 1100X has the bigger amplifier - 650W against 300W RMS, about 3.4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | 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. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction and app control). |
| Cabinet size | depends | MartinLogan 800X is about 43% 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 | B | MartinLogan 800X costs less - $900 against $1,500, about 40% less. |
A MartinLogan 1100X B MartinLogan 800X
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 800X costs about 40% less. In a normal room, placement will make a bigger difference than the gap between these two. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $900 each, two MartinLogan 800X cost about $1,800 against $1,500 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - MartinLogan 800X is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
