In this review, we will be comparing Nostala FT12 and ForceField 40, two Powered Subwoofer speakers from Emotiva 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 Emotiva Nostala FT12 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 Emotiva Nostala FT12and GoldenEar ForceField 40 have a single woofer setup however the Emotiva Nostala FT12's woofer is 12-inch whereas the GoldenEar ForceField 40 features a 10-inch woofer.
Frequency Response
Nostala FT12 has a frequency range of 25-150 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 Nostala FT12's min frequency of 25Hz.
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 Emotiva Nostala FT12 has a Bass Reflex type cabinet. 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. On the other hand the GoldenEar ForceField 40 have Passive Radiator type enclosure. 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.
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 Emotiva Nostala FT12's and GoldenEar ForceField 40's external dimensions. Emotiva Nostala FT12 has external dimensions of 495.0 x 387.0 x 508.0mm (19-1/2 x 15-1/4 x 20inch) 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).
Emotiva Nostala FT12 is clearly the larger of the two speakers. Its body is 48mm wider, 117mm taller and 23mm deeper than GoldenEar ForceField 40.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Emotiva Nostala FT12 needs about 20% more floor or shelf area. Emotiva Nostala FT12 is 23mm deeper, so it stands that much further out from the wall. Emotiva Nostala FT12 is 117mm taller.
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 Emotiva Nostala FT12 is approximately 1966.0cm2 / 304.7inch2 and base area of the GoldenEar ForceField 40 is approximately 1644.2cm2 / 254.9inch2. The Nostala FT12 requires 20% 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 Emotiva Nostala FT12 weighs 30.84kg / 67.8lbs and the GoldenEar ForceField 40 weighs 18.41kg / 40.5lbs. This makes the Nostala FT12 68% heavier than the ForceField 40.
Here is a comparison of how Nostala FT12 and ForceField 40's weights compare with the average, max and min weights in Powered Subwoofer class.

A ported 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 25Hz. 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 40 has the bigger amplifier - 1000W against 800W RMS, about 1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Emotiva Nostala FT12 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Emotiva Nostala FT12 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; 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. |
| Phase control | A | Emotiva Nostala FT12 has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Driver placement | depends | Emotiva Nostala FT12 fires front and GoldenEar ForceField 40 fires front/down. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | GoldenEar ForceField 40 is about 36% 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 | Emotiva Nostala FT12 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 | B | GoldenEar ForceField 40 costs less - $1,199 against $1,799, about 33% less. |
A Emotiva Nostala FT12 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?
Emotiva Nostala FT12 is ahead, but on only 1 of the measured areas, and it costs about 50% more. GoldenEar ForceField 40 is the sensible buy unless your room is large enough to need the extra. 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.
