In this review, we will be comparing Dynamo 600X and ASW610, two Powered Subwoofer speakers from MartinLogan and Bowers Wilkins. 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 B&W ASW610 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 600Xand B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Dynamo 600X has a frequency range of 27-200 Hz whereas ASW610 has a frequency range of 27-140 Hz.
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 B&W ASW610 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 B&W ASW610'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 B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm (12-5/8 x 12-1/4 x 15-1/2inch).
MartinLogan 600X is clearly the larger of the two speakers. Its body is 57mm wider, 94mm taller and 26mm deeper than B&W ASW610.

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 B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Dynamo 600X requires 26% more surface area than the ASW610 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 600X weighs 15.91kg / 35lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Dynamo 600X 27% heavier than the ASW610.
Here is a comparison of how Dynamo 600X and ASW610'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 600X needs about 26% more floor area. MartinLogan 600X stands 26mm further into the room. MartinLogan 600X is 94mm 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 | evenly matched | Effectively the same reach (27Hz vs 27Hz). |
| Amplifier power | B | B&W ASW610 has the bigger amplifier - 200W against 120W RMS, about 2.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| 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; B&W ASW610 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. |
| Wireless option | depends | Only MartinLogan 600X offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Driver placement | depends | MartinLogan 600X fires down and B&W ASW610 fires front. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | B&W ASW610 is about 39% 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. |
| Warranty | A | MartinLogan 600X carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | MartinLogan 600X costs less - $700 against $899, about 22% less. |
A MartinLogan 600X B B&W ASW610
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. 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, B&W ASW610 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - B&W ASW610 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.
