In this review, we will be comparing Nero DueVoce DualX8 and 3000 Micro R Evolution, two Powered Subwoofer speakers from OSD and SVS. 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 SVS 3000 Micro R Evolution 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 DualX8 and SVS 3000 Micro R Evolution have a totally different setup: the OSD Nero DueVoce DualX8 features 1 x 8-inch drivers whereas the 3000 Micro R Evolution features 2 x 9-inch drivers.
Frequency Response
Nero DueVoce DualX8 has a frequency range of 17-165 Hz whereas 3000 Micro R Evolution has a frequency range of 20-230 Hz. With a minimum frequency of 17Hz, the Nero DueVoce DualX8 can go slightly deeper then the 3000 Micro R Evolution'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 SVS 3000 Micro R Evolution's external dimensions. OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm () whereas SVS 3000 Micro R Evolution has external dimensions of 277.8 x 301.0 x 313.0mm ().
SVS 3000 Micro R Evolution is 33.4mm shorter and 20.4mm less deeper than OSD Nero DueVoce DualX8 but it is also 35.9mm wider.
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 SVS 3000 Micro R Evolution is approximately 942.1cm2 / 146.0inch2. The Nero DueVoce DualX8 requires 6% less surface area than the 3000 Micro R Evolution 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 SVS 3000 Micro R Evolution weighs 10.23kg / 22.5lbs. This makes the 3000 Micro R Evolution 31% heavier than the Nero DueVoce DualX8.
Here is a comparison of how Nero DueVoce DualX8 and 3000 Micro R Evolution'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. OSD Nero DueVoce DualX8 stands 20mm further into the room. OSD Nero DueVoce DualX8 is 33mm taller.

A passive radiator subwoofer against a sealed 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 | 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 | SVS 3000 Micro R Evolution has the bigger amplifier - 1200W against 130W RMS, about 9.7dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS 3000 Micro R Evolution moves more air: 2 x 9" against 8" is 2.53x the cone area, not the 1.59x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | OSD Nero DueVoce DualX8 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; SVS 3000 Micro R Evolution is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Warranty | B | SVS 3000 Micro R Evolution carries 5 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 $999, about 70% 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?
The usual trade-off: SVS 3000 Micro R Evolution measures better, OSD Nero DueVoce DualX8 costs about 70% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, OSD Nero DueVoce DualX8 will hit harder for the money; if it is mainly for music in a normal-sized room, SVS 3000 Micro R Evolution is usually the easier one to make sound right. 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 $999 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.
