In this review, we will be comparing DS153 and ForceField 4, two Powered Subwoofer speakers from ELAC 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 ELAC DS153 and GoldenEar ForceField 4 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 ELAC DS153and GoldenEar ForceField 4 have a single woofer setup however the ELAC DS153's woofer is 15-inch whereas the GoldenEar ForceField 4 features a 10-inch woofer.
Frequency Response
DS153 has a frequency range of 20-150 Hz whereas ForceField 4 has a frequency range of 14-250 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 DS153's min frequency of 20Hz.
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 ELAC DS153's and GoldenEar ForceField 4's external dimensions. ELAC DS153 has external dimensions of 485.8 x 469.9 x 552.5mm () whereas GoldenEar ForceField 4 has external dimensions of 331.0 x 340.0 x 482.0mm (13inch x 13-3/8inch x 18-15/16inch).
ELAC DS153 is clearly the larger of the two speakers. Its body is 129.9mm wider, 154.8mm taller and 70.5mm deeper than GoldenEar ForceField 4.
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 ELAC DS153 is approximately 2596.2cm2 / 402.4inch2 and base area of the GoldenEar ForceField 4 is approximately 1638.8cm2 / 254.0inch2. The DS153 requires 58% more surface area than the ForceField 4 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 ELAC DS153 weighs 25.10kg / 55.2lbs and the GoldenEar ForceField 4 weighs 14.55kg / 32lbs. This makes the DS153 73% heavier than the ForceField 4.
Here is a comparison of how DS153 and ForceField 4'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.
ELAC DS153 needs about 58% more floor area. ELAC DS153 stands 71mm further into the room. ELAC DS153 is 155mm taller.

A sealed subwoofer against a passive radiator 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 | B | GoldenEar ForceField 4 goes deeper - 14Hz against 20Hz. 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 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 | A | ELAC DS153 moves more air: 15" against 10" is 2.25x the cone area, not the 1.5x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | ELAC DS153 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; GoldenEar ForceField 4 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Cabinet size | depends | GoldenEar ForceField 4 is about 57% 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 | B | 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 | B | GoldenEar ForceField 4 costs less - $799 against $949, about 16% less. |
A ELAC DS153 B GoldenEar ForceField 4
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 is the easier recommendation: it leads on most of the measured areas and costs less. Take ELAC DS153 if one of the "depends" rows describes your room. 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 DS153 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.
