In this review, we will be comparing ForceField 4 and SUB3070, two Powered Subwoofer speakers from GoldenEar and ELAC. 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 ELAC SUB3070 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 4and ELAC SUB3070 have a single woofer setup however the GoldenEar ForceField 4's woofer is 10-inch whereas the ELAC SUB3070 features a 12-inch woofer.
Frequency Response
ForceField 4 has a frequency range of 14-250 Hz whereas SUB3070 has a frequency range of 18-180 Hz. With a minimum frequency of 14Hz, the ForceField 4 can go slightly deeper then the SUB3070'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
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 ELAC SUB3070 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 ELAC SUB3070'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 ELAC SUB3070 has external dimensions of 435.0 x 520.0 x 477.0mm (17-1/8 x 20-7/16 x 18-3/4inch).
GoldenEar ForceField 4 is 180mm narrower and 104mm shorter than ELAC SUB3070 but it is also 5mm 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.
ELAC SUB3070 needs about 51% more floor or shelf area. ELAC SUB3070 is 104mm 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 ELAC SUB3070 is approximately 2480.4cm2 / 384.5inch2. The ForceField 4 requires 34% less surface area than the SUB3070 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 4 weighs 14.55kg / 32lbs and the ELAC SUB3070 weighs 35.00kg / 77lbs. This makes the SUB3070 141% heavier than the ForceField 4.
Here is a comparison of how ForceField 4 and SUB3070's weights compare with the average, max and min weights in Powered Subwoofer class.

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 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 (1200W vs 1200W RMS) - under 1dB apart. |
| Driver area | B | ELAC SUB3070 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | GoldenEar ForceField 4 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; ELAC SUB3070 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 ELAC SUB3070 offers a wireless link. It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Phase control | B | ELAC SUB3070 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 ELAC SUB3070 fires side. 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 4 is about 50% 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 | GoldenEar ForceField 4 carries 3 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | GoldenEar ForceField 4 costs less - $799 against $999, about 20% less. |
A GoldenEar ForceField 4 B ELAC SUB3070
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, GoldenEar ForceField 4 will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC SUB3070 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 4 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.
