In this review, we will be comparing ForceField 30 and ForceField 40, two Powered Subwoofer speakers by 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 GoldenEar ForceField 30 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.Both GoldenEar ForceField 30and GoldenEar ForceField 40 have a single woofer setup however the GoldenEar ForceField 30's woofer is 8-inch whereas the GoldenEar ForceField 40 features a 10-inch woofer.
Frequency Response
ForceField 30 has a frequency range of 18-250 Hz whereas ForceField 40 has a frequency range of 14-250 Hz. With a minimum frequency of 14Hz, the ForceField 40 can go slightly deeper then the ForceField 30's min frequency of 18Hz.
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
Both GoldenEar ForceField 30 and GoldenEar ForceField 40 have Passive Radiator type cabinets. 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.
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 30's and GoldenEar ForceField 40's external dimensions. GoldenEar ForceField 30 has external dimensions of 324.0 x 291.0 x 421.0mm (12-3/4inch x 11-7/16inch x 16-9/16inch) 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 clearly the larger of the two speakers. Its body is 48mm wider, 54mm taller and 64mm deeper than GoldenEar ForceField 30.
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 30 is approximately 1225.1cm2 / 189.9inch2 and base area of the GoldenEar ForceField 40 is approximately 1644.2cm2 / 254.9inch2. The ForceField 30 requires 25% less surface area than the ForceField 40 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 30 weighs 14.32kg / 31.5lbs and the GoldenEar ForceField 40 weighs 18.41kg / 40.5lbs. This makes the ForceField 40 29% heavier than the ForceField 30.
Here is a comparison of how ForceField 30 and ForceField 40'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 40 needs about 34% more floor area. GoldenEar ForceField 40 stands 64mm further into the room. GoldenEar ForceField 40 is 54mm taller.

Siblings in GoldenEar's ForceField range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | B | GoldenEar ForceField 40 goes deeper - 14Hz against 18Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | evenly matched | Much the same amplifier (1000W vs 1000W RMS) - under 1dB apart. |
| Driver area | B | GoldenEar ForceField 40 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 | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Cabinet size | depends | GoldenEar ForceField 30 is about 36% 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 30 costs less - $899 against $1,199, about 25% less. |
A GoldenEar ForceField 30 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?
The usual trade-off: GoldenEar ForceField 40 measures better, GoldenEar ForceField 30 costs about 25% less. In a normal room, placement will make a bigger difference than the gap between these two. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 30 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.
