In this review, we will be comparing ForceField 4 and Dynamo 800X, 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 4 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.GoldenEar ForceField 4and MartinLogan 800X have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
ForceField 4 has a frequency range of 14-250 Hz whereas Dynamo 800X has a frequency range of 24-200 Hz. With a minimum frequency of 14Hz, the ForceField 4 can go significantly deeper on the low side and provide stronger bass compared to 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
The GoldenEar ForceField 4 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 800X 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 GoldenEar ForceField 4's and MartinLogan 800X's external dimensions. GoldenEar ForceField 4 has external dimensions of 331.0 x 340.0 x 482.0mm (13inch x 13-3/8inch x 18-15/16inch) 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 800X is 22mm narrower and 132mm less deeper than GoldenEar ForceField 4 but it is also 20mm 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 GoldenEar ForceField 4 is approximately 1638.8cm2 / 254.0inch2 and base area of the MartinLogan 800X is approximately 1113.0cm2 / 172.5inch2. The ForceField 4 requires 47% 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 GoldenEar ForceField 4 weighs 14.55kg / 32lbs and the MartinLogan 800X weighs 13.64kg / 30lbs. This makes the ForceField 4 7% heavier than the Dynamo 800X.
Here is a comparison of how ForceField 4 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.
GoldenEar ForceField 4 needs about 47% more floor area. GoldenEar ForceField 4 stands 132mm further into the room. MartinLogan 800X is 20mm taller.

A passive radiator 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 | A | GoldenEar ForceField 4 goes deeper - 14Hz against 24Hz. 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 4 has the bigger amplifier - 1200W against 300W RMS, about 6dB 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 | GoldenEar ForceField 4 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; MartinLogan 800X 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 800X 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 800X 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 4 fires front and MartinLogan 800X fires front/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 | MartinLogan 800X is about 28% 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 4 costs less - $799 against $900, about 11% less. |

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?
GoldenEar ForceField 4 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, GoldenEar ForceField 4 will hit harder for the money; if it is mainly for music in a normal-sized room, MartinLogan 800X is usually the easier one to make sound right.
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.
