In this review, we will be comparing Nero DueVoce DualX8 and ForceField 30, two Powered Subwoofer speakers from OSD 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 OSD Nero DueVoce DualX8 and GoldenEar ForceField 30 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.OSD Nero DueVoce DualX8and GoldenEar ForceField 30 have the same driver set up: Both subwoofers have 1 x 8" drivers.
Frequency Response
Nero DueVoce DualX8 has a frequency range of 17-165 Hz whereas ForceField 30 has a frequency range of 18-250 Hz. With a minimum frequency of 17Hz, the Nero DueVoce DualX8 can go slightly deeper then the ForceField 30's min frequency of 18Hz.
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 OSD Nero DueVoce DualX8's and GoldenEar ForceField 30's external dimensions. OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm () whereas GoldenEar ForceField 30 has external dimensions of 324.0 x 291.0 x 421.0mm (12-3/4inch x 11-7/16inch x 16-9/16inch).
GoldenEar ForceField 30 is clearly the larger of the two speakers. Its body is 25.9mm wider, 12.8mm taller and 87.6mm deeper than OSD Nero DueVoce DualX8.
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 OSD Nero DueVoce DualX8 is approximately 883.8cm2 / 137.0inch2 and base area of the GoldenEar ForceField 30 is approximately 1225.1cm2 / 189.9inch2. The Nero DueVoce DualX8 requires 28% less surface area than the ForceField 30 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 OSD Nero DueVoce DualX8 weighs 7.80kg / 17.2lbs and the GoldenEar ForceField 30 weighs 14.32kg / 31.5lbs. This makes the ForceField 30 84% heavier than the Nero DueVoce DualX8.
Here is a comparison of how Nero DueVoce DualX8 and ForceField 30'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.
GoldenEar ForceField 30 needs about 39% more floor area. GoldenEar ForceField 30 stands 88mm further into the room. GoldenEar ForceField 30 is 13mm taller.

Different price classes - GoldenEar ForceField 30 costs roughly 3x what OSD Nero DueVoce DualX8 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (17Hz vs 18Hz). |
| Amplifier power | B | GoldenEar ForceField 30 has the bigger amplifier - 1000W against 130W RMS, about 8.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (8" against 8"). |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Cabinet size | depends | OSD Nero DueVoce DualX8 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 | B | GoldenEar ForceField 30 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 | OSD Nero DueVoce DualX8 costs less - $300 against $899, about 67% less. |
A OSD Nero DueVoce DualX8 B GoldenEar ForceField 30
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?
The usual trade-off: GoldenEar ForceField 30 measures better, OSD Nero DueVoce DualX8 costs about 67% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $300 each, two OSD Nero DueVoce DualX8 cost about $600 against $899 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - OSD Nero DueVoce DualX8 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.
