In this review, we will be comparing ForceField 3 and Monitor XT12, two Powered Subwoofer speakers from GoldenEar and Polk Audio. 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 Polk Monitor XT12 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 Polk Monitor XT12 have a single woofer setup however the GoldenEar ForceField 3's woofer is 8-inch whereas the Polk Monitor XT12 features a 12-inch woofer.
Frequency Response
ForceField 3 has a frequency range of 18-250 Hz whereas Monitor XT12 has a frequency range of 24-160 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 Monitor XT12'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 Polk Monitor XT12 have Bass Reflex type enclosure. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the 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 3's and Polk Monitor XT12'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 Polk Monitor XT12 has external dimensions of 418.0 x 408.0 x 485.0mm (16-7/16inch x 16-1/16inch x 19-1/16inch).
Polk Monitor XT12 is clearly the larger of the two speakers. Its body is 115mm wider, 130mm taller and 53mm deeper than GoldenEar ForceField 3.
Below you can see the front view size comparison of GoldenEar ForceField 3 and Polk Monitor XT12 in scale.

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 Polk Monitor XT12 is approximately 1978.8cm2 / 306.7inch2. The ForceField 3 requires 36% less surface area than the Monitor XT12 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 Polk Monitor XT12 weighs 17.73kg / 39lbs. This makes the Monitor XT12 50% heavier than the ForceField 3.
Here is a comparison of how ForceField 3 and Monitor XT12'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.
Polk Monitor XT12 needs about 56% more floor area. Polk Monitor XT12 stands 53mm further into the room. Polk Monitor XT12 is 130mm taller.

A passive radiator subwoofer against a ported 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 50W RMS, about 13dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Polk Monitor XT12 moves more air: 12" against 8" 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 | GoldenEar ForceField 3 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; Polk Monitor XT12 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Phase control | B | Polk Monitor XT12 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 56% 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 | Polk Monitor XT12 costs less - $399 against $599, about 33% less. |
A GoldenEar ForceField 3 B Polk Monitor XT12
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. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 3 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.
