In this review, we will be comparing Nero DueVoce DualX8 and SuperCube 2000, two Powered Subwoofer speakers from OSD and Definitive Technology. 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 DT SuperCube 2000 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 OSD Nero DueVoce DualX8and DT SuperCube 2000 have a single woofer setup however the OSD Nero DueVoce DualX8's woofer is 8-inch whereas the DT SuperCube 2000 features a 7.5-inch woofer.
Frequency Response
Nero DueVoce DualX8 has a frequency range of 17-165 Hz whereas SuperCube 2000 has a frequency range of 20-200 Hz. With a minimum frequency of 17Hz, the Nero DueVoce DualX8 can go slightly deeper then the SuperCube 2000's min frequency of 20Hz.
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 DT SuperCube 2000's external dimensions. OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm () whereas DT SuperCube 2000 has external dimensions of 275.0 x 261.0 x 321.0mm (10-13/16 x 10-1/4 x 12-5/8inch).
OSD Nero DueVoce DualX8 is clearly the larger of the two speakers. Its body is 4.1mm wider, 36.2mm taller and 12.4mm deeper than DT SuperCube 2000.
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.

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 DT SuperCube 2000 is approximately 837.8cm2 / 129.9inch2. The Nero DueVoce DualX8 requires 5% more surface area than the SuperCube 2000 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 OSD Nero DueVoce DualX8 weighs 7.80kg / 17.2lbs and the DT SuperCube 2000 weighs 11.36kg / 25lbs. This makes the SuperCube 2000 46% heavier than the Nero DueVoce DualX8.
Here is a comparison of how Nero DueVoce DualX8 and SuperCube 2000's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - DT SuperCube 2000 costs roughly 2x what OSD Nero DueVoce DualX8 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | OSD Nero DueVoce DualX8 goes deeper - 17Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | DT SuperCube 2000 has the bigger amplifier - 650W against 130W RMS, about 7dB 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 7.5"). |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Warranty | B | DT SuperCube 2000 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 $599, about 50% less. |
A OSD Nero DueVoce DualX8 B DT SuperCube 2000
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?
DT SuperCube 2000 is ahead, but on only 1 of the measured areas, and it costs about 100% more. OSD Nero DueVoce DualX8 is the sensible buy unless your room is large enough to need the extra. 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 $599 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.
