In this review, we will be comparing Abyss 10 and ForceField 40, two Powered Subwoofer speakers from MartinLogan and GoldenEar. 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 Abyss 10 and GoldenEar ForceField 40 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 Abyss 10and GoldenEar ForceField 40 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Abyss 10 has a frequency range of 22-200 Hz whereas ForceField 40 has a frequency range of 14-250 Hz. With a minimum frequency of 14Hz, the ForceField 40 can go significantly deeper on the low side and provide stronger bass compared to the Abyss 10's min frequency of 22Hz.
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.

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 Abyss 10's and GoldenEar ForceField 40's external dimensions. MartinLogan Abyss 10 has external dimensions of 392.1 x 406.4 x 438.2mm () whereas GoldenEar ForceField 40 has external dimensions of 378.0 x 339.0 x 485.0mm (14-7/8inch x 13-5/16inch x 19-1/16inch).
GoldenEar ForceField 40 is 67.4mm narrower and 14.1mm shorter than MartinLogan Abyss 10 but it is also 46.8mm deeper.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
MartinLogan Abyss 10 needs about 8% more floor or shelf area. GoldenEar ForceField 40 is 47mm deeper, so it stands that much further out from the wall. MartinLogan Abyss 10 is 14mm 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 MartinLogan Abyss 10 is approximately 1780.8cm2 / 276.0inch2 and base area of the GoldenEar ForceField 40 is approximately 1644.2cm2 / 254.9inch2. The Abyss 10 requires 8% more surface area than the ForceField 40 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 Abyss 10 weighs 25.22kg / 55.5lbs and the GoldenEar ForceField 40 weighs 18.41kg / 40.5lbs. This makes the Abyss 10 37% heavier than the ForceField 40.
Here is a comparison of how Abyss 10 and ForceField 40's weights compare with the average, max and min weights in Powered Subwoofer class.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | GoldenEar ForceField 40 goes deeper - 14Hz against 22Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | GoldenEar ForceField 40 has the bigger amplifier - 1000W against 800W RMS, about 1dB 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 | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Price | B | GoldenEar ForceField 40 costs less - $1,199 against $1,900, about 37% less. |
A MartinLogan Abyss 10 B GoldenEar ForceField 40
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 40 is the easier recommendation: it leads on most of the measured areas and costs less. Take MartinLogan Abyss 10 if one of the "depends" rows describes your room. 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 $1,199 each, two GoldenEar ForceField 40 cost about $2,398 against $1,900 for one of the other, which is worth a thought.
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.
