In this review, we will be comparing Nero DueVoce DualX8 and Debut 2.0 SUB3010, two Powered Subwoofer speakers from OSD and ELAC. 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 ELAC Debut 2.0 SUB3010 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.

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 ELAC Debut 2.0 SUB3010's external dimensions. OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm () whereas ELAC Debut 2.0 SUB3010 has external dimensions of 374.0 x 355.0 x 383.0mm (14-11/16 x 13-15/16 x 15-1/16inch).
ELAC Debut 2.0 SUB3010 is clearly the larger of the two speakers. Its body is 89.9mm wider, 62.8mm taller and 49.6mm 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 ELAC Debut 2.0 SUB3010 is approximately 1359.7cm2 / 210.8inch2. The Nero DueVoce DualX8 requires 35% less surface area than the Debut 2.0 SUB3010 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 ELAC Debut 2.0 SUB3010 weighs 14.59kg / 32.1lbs. This makes the Debut 2.0 SUB3010 87% heavier than the Nero DueVoce DualX8.
Here is a comparison of how Nero DueVoce DualX8 and Debut 2.0 SUB3010's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - ELAC Debut 2.0 SUB3010 costs roughly 2.2x 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 28Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | ELAC Debut 2.0 SUB3010 has the bigger amplifier - 200W against 130W RMS, about 1.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | ELAC Debut 2.0 SUB3010 moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| 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 46% 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 | OSD Nero DueVoce DualX8 carries 2 years on parts against 1 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 $650, about 54% less. |
A OSD Nero DueVoce DualX8 B ELAC Debut 2.0 SUB3010
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. 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 $650 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.
