In this review, we will be comparing HT 1510 Predator and ForceField 40, two Powered Subwoofer speakers from REL 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 REL HT 1510 Predator 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 REL HT 1510 Predatorand GoldenEar ForceField 40 have a single woofer setup however the REL HT 1510 Predator's woofer is 15-inch whereas the GoldenEar ForceField 40 features a 10-inch woofer.
Frequency Response
HT 1510 Predator has a frequency range of 20-200 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 HT 1510 Predator'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 REL HT 1510 Predator's and GoldenEar ForceField 40's external dimensions. REL HT 1510 Predator has external dimensions of 458.8 x 542.9 x 544.5mm () 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).
REL HT 1510 Predator is clearly the larger of the two speakers. Its body is 203.9mm wider, 80.8mm taller and 59.5mm deeper than GoldenEar ForceField 40.
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 REL HT 1510 Predator is approximately 2956.1cm2 / 458.2inch2 and base area of the GoldenEar ForceField 40 is approximately 1644.2cm2 / 254.9inch2. The HT 1510 Predator requires 80% 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 REL HT 1510 Predator weighs 45.22kg / 99.5lbs and the GoldenEar ForceField 40 weighs 18.41kg / 40.5lbs. This makes the HT 1510 Predator 146% heavier than the ForceField 40.
Here is a comparison of how HT 1510 Predator 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.
REL HT 1510 Predator needs about 80% more floor area. REL HT 1510 Predator stands 60mm further into the room. REL HT 1510 Predator is 81mm 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 40 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 | evenly matched | Much the same amplifier (1000W vs 1000W RMS) - under 1dB apart. |
| Driver area | A | REL HT 1510 Predator 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 | REL HT 1510 Predator is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; GoldenEar ForceField 40 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 40 is about 54% 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 | B | GoldenEar ForceField 40 costs less - $1,199 against $1,799, about 33% less. |
A REL HT 1510 Predator 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?
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 40 will hit harder for the money; if it is mainly for music in a normal-sized room, REL HT 1510 Predator is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 40 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.
