In this review, we will be comparing ForceField 3 and Dynamo 600X, two Powered Subwoofer speakers from GoldenEar and 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 GoldenEar ForceField 3 and MartinLogan 600X 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 GoldenEar ForceField 3and MartinLogan 600X have a single woofer setup however the GoldenEar ForceField 3's woofer is 8-inch whereas the MartinLogan 600X features a 10-inch woofer.
Frequency Response
ForceField 3 has a frequency range of 18-250 Hz whereas Dynamo 600X has a frequency range of 27-200 Hz. With a minimum frequency of 18Hz, the ForceField 3 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 GoldenEar ForceField 3 has a Passive Radiator type cabinet. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs. On the other hand the MartinLogan 600X have Bass reflex type enclosure.
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 GoldenEar ForceField 3's and MartinLogan 600X's external dimensions. GoldenEar ForceField 3 has external dimensions of 288.0 x 293.0 x 432.0mm (11-5/16inch x 11-1/2inch x 17inch) whereas 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).
GoldenEar ForceField 3 is 76mm narrower and 127mm shorter than MartinLogan 600X but it is also 12mm deeper.

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 GoldenEar ForceField 3 is approximately 1265.8cm2 / 196.2inch2 and base area of the MartinLogan 600X is approximately 1549.8cm2 / 240.2inch2. The ForceField 3 requires 18% less surface area than the Dynamo 600X 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 GoldenEar ForceField 3 weighs 11.82kg / 26lbs and the MartinLogan 600X weighs 15.91kg / 35lbs. This makes the Dynamo 600X 35% heavier than the ForceField 3.
Here is a comparison of how ForceField 3 and Dynamo 600X'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 22% more floor area. MartinLogan 600X is 127mm taller.

A passive radiator subwoofer against a ported 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 | A | GoldenEar ForceField 3 goes deeper - 18Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | GoldenEar ForceField 3 has the bigger amplifier - 1000W against 120W RMS, about 9.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | MartinLogan 600X moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | GoldenEar ForceField 3 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; 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. 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. |
| Phase control | B | MartinLogan 600X has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Driver placement | depends | GoldenEar ForceField 3 fires front and MartinLogan 600X fires down. 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 | GoldenEar ForceField 3 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 | A | GoldenEar ForceField 3 costs less - $599 against $700, about 14% less. |
A GoldenEar ForceField 3 B MartinLogan 600X
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. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 3 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.
