In this review, we will be comparing ForceField 3 and KUBE 10b, two Powered Subwoofer speakers from GoldenEar and KEF. 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 3 and KEF KUBE 10b 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 3and KEF KUBE 10b have a single woofer setup however the GoldenEar ForceField 3's woofer is 8-inch whereas the KEF KUBE 10b features a 10-inch woofer.
Frequency Response
ForceField 3 has a frequency range of 18-250 Hz whereas KUBE 10b has a frequency range of 24-140 Hz. With a minimum frequency of 18Hz, the ForceField 3 can go significantly deeper on the low side and provide stronger bass compared to the KUBE 10b's min frequency of 24Hz.
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 3 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 KEF KUBE 10b 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 3's and KEF KUBE 10b's external dimensions. GoldenEar ForceField 3 has external dimensions of 288.0 x 293.0 x 432.0mm (11-5/16inch x 11-1/2inch x 17inch) whereas KEF KUBE 10b has external dimensions of 372.0 x 356.0 x 397.0mm (14-5/8 x 14 x 15-5/8inch).
GoldenEar ForceField 3 is 63mm narrower and 84mm shorter than KEF KUBE 10b but it is also 35mm deeper.

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 3 is approximately 1265.8cm2 / 196.2inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The ForceField 3 requires 10% less surface area than the KUBE 10b 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 3 weighs 11.82kg / 26lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the KUBE 10b 48% heavier than the ForceField 3.
Here is a comparison of how ForceField 3 and KUBE 10b'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.
KEF KUBE 10b needs about 12% more floor area. GoldenEar ForceField 3 stands 35mm further into the room. KEF KUBE 10b is 84mm taller.

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 3 goes deeper - 18Hz against 24Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | GoldenEar ForceField 3 has the bigger amplifier - 1000W against 300W RMS, about 5.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | KEF KUBE 10b 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 | depends | GoldenEar ForceField 3 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; KEF KUBE 10b 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. |
| Speaker-level inputs | A | GoldenEar ForceField 3 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Wireless option | depends | Only KEF KUBE 10b offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Phase control | B | KEF KUBE 10b has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Cabinet size | depends | GoldenEar ForceField 3 is about 31% 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 3 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | GoldenEar ForceField 3 costs less - $599 against $750, about 20% less. |
A GoldenEar ForceField 3 B KEF KUBE 10b
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 3 is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF KUBE 10b if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, GoldenEar ForceField 3 will hit harder for the money; if it is mainly for music in a normal-sized room, KEF KUBE 10b is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, GoldenEar ForceField 3 is the only one of these two you can connect at all.
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.
