In this review, we will be comparing ForceField 4 and Concerta2 B10, two Powered Subwoofer speakers from GoldenEar and Revel. 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 Revel Concerta2 B10 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.GoldenEar ForceField 4and Revel Concerta2 B10 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
ForceField 4 has a frequency range of 14-250 Hz whereas Concerta2 B10 has a frequency range of 35-150 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 Concerta2 B10's min frequency of 35Hz.
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 Revel Concerta2 B10 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 4's and Revel Concerta2 B10'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 Revel Concerta2 B10 has external dimensions of 420.0 x 377.0 x 440.0mm (16-1/2 x 14-13/16 x 17-5/16inch).
GoldenEar ForceField 4 is 37mm narrower and 89mm shorter than Revel Concerta2 B10 but it is also 42mm 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 4 is approximately 1638.8cm2 / 254.0inch2 and base area of the Revel Concerta2 B10 is approximately 1658.8cm2 / 257.1inch2. The ForceField 4 requires 1% less surface area than the Concerta2 B10 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 Revel Concerta2 B10 weighs 21.36kg / 47lbs. This makes the Concerta2 B10 47% heavier than the ForceField 4.
Here is a comparison of how ForceField 4 and Concerta2 B10'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.
Near-identical footprints. GoldenEar ForceField 4 stands 42mm further into the room. Revel Concerta2 B10 is 89mm 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 4 goes deeper - 14Hz against 35Hz. 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 4 has the bigger amplifier - 1200W against 800W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | GoldenEar ForceField 4 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; Revel Concerta2 B10 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. |
| Speaker-level inputs | A | GoldenEar ForceField 4 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. |
| Phase control | B | Revel Concerta2 B10 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 4 is about 22% 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 | Revel Concerta2 B10 carries 5 years on parts against 3 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 $1,650, about 52% less. |

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 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Check your amplifier first: if it has no subwoofer or preamp output, GoldenEar ForceField 4 is the only one of these two you can connect at all. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $799 each, two GoldenEar ForceField 4 cost about $1,598 against $1,650 for one of the other, which is worth a thought.
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.
