In this review, we will be comparing Dynamo 600X and Dynamo 1600X, 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 600X and MartinLogan 1600X 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 600Xand MartinLogan 1600X have a single woofer setup however the MartinLogan 600X's woofer is 10-inch whereas the MartinLogan 1600X features a 15-inch woofer.
Frequency Response
Dynamo 600X has a frequency range of 27-200 Hz whereas Dynamo 1600X has a frequency range of 20-200 Hz. With a minimum frequency of 20Hz, the Dynamo 1600X can go significantly deeper on the low side and provide stronger bass compared to the Dynamo 600X's min frequency of 27Hz.
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
The MartinLogan 600X has a Bass reflex type cabinet. On the other hand the MartinLogan 1600X have Acoustic Suspension type enclosure. 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 600X's and MartinLogan 1600X's external dimensions. MartinLogan 600X has external dimensions of 415.0 x 369.0 x 420.0mm (16-5/16 x 14-1/2 x 16-1/2inch) whereas MartinLogan 1600X has external dimensions of 510.0 x 456.0 x 470.0mm (20-1/16 x 17-15/16 x 18-1/2inch).
MartinLogan 1600X is clearly the larger of the two speakers. Its body is 87mm wider, 95mm taller and 50mm deeper than MartinLogan 600X.
Below you can see the front view size comparison of MartinLogan 600X and MartinLogan 1600X in scale.

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 600X is approximately 1549.8cm2 / 240.2inch2 and base area of the MartinLogan 1600X is approximately 2143.2cm2 / 332.2inch2. The Dynamo 600X requires 28% less surface area than the Dynamo 1600X 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 600X weighs 15.91kg / 35lbs and the MartinLogan 1600X weighs 25.91kg / 57lbs. This makes the Dynamo 1600X 63% heavier than the Dynamo 600X.
Here is a comparison of how Dynamo 600X and Dynamo 1600X'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 1600X needs about 38% more floor area. MartinLogan 1600X stands 50mm further into the room. MartinLogan 1600X is 95mm taller.

A ported subwoofer against a sealed 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 | MartinLogan 1600X goes deeper - 20Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | MartinLogan 1600X has the bigger amplifier - 900W against 120W RMS, about 8.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | MartinLogan 1600X moves more air: 15" against 10" is 2.25x the cone area, not the 1.5x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | MartinLogan 600X is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; MartinLogan 1600X is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction and app control). |
| Speaker-level inputs | A | MartinLogan 600X takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | MartinLogan 600X is about 41% 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 600X costs less - $700 against $2,000, about 65% less. |
A MartinLogan 600X B MartinLogan 1600X
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 1600X measures better, MartinLogan 600X costs about 65% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, MartinLogan 600X will hit harder for the money; if it is mainly for music in a normal-sized room, MartinLogan 1600X is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, MartinLogan 600X is the only one of these two you can connect at all.
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.
