In this review, we will be comparing Vestra W10 and Nero DueVoce DualX8, two Powered Subwoofer speakers from Monitor Audio and OSD. 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 Monitor Audio Vestra W10 and OSD Nero DueVoce DualX8 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 Monitor Audio Vestra W10and OSD Nero DueVoce DualX8 have a single woofer setup however the Monitor Audio Vestra W10's woofer is 10.0-inch whereas the OSD Nero DueVoce DualX8 features a 8-inch woofer.
Frequency Response
Vestra W10 has a frequency range of 19-200 Hz whereas Nero DueVoce DualX8 has a frequency range of 17-165 Hz. With a minimum frequency of 17Hz, the Nero DueVoce DualX8 can go slightly deeper then the Vestra W10's min frequency of 19Hz.
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 Monitor Audio Vestra W10's and OSD Nero DueVoce DualX8's external dimensions. Monitor Audio Vestra W10 has external dimensions of 342.9 x 330.2 x 403.2mm () whereas OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm ().
Monitor Audio Vestra W10 is clearly the larger of the two speakers. Its body is 65.1mm wider, 31.7mm taller and 69.8mm 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 Monitor Audio Vestra W10 is approximately 1331.4cm2 / 206.4inch2 and base area of the OSD Nero DueVoce DualX8 is approximately 883.8cm2 / 137.0inch2. The Vestra W10 requires 51% more surface area than the Nero DueVoce DualX8 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 Monitor Audio Vestra W10 weighs 13.29kg / 29.2lbs and the OSD Nero DueVoce DualX8 weighs 7.80kg / 17.2lbs. This makes the Vestra W10 70% heavier than the Nero DueVoce DualX8.
Here is a comparison of how Vestra W10 and Nero DueVoce DualX8'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.
Monitor Audio Vestra W10 needs about 51% more floor area. Monitor Audio Vestra W10 stands 70mm further into the room. Monitor Audio Vestra W10 is 32mm taller.

A sealed 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 | evenly matched | Effectively the same reach (19Hz vs 17Hz). |
| Amplifier power | A | Monitor Audio Vestra W10 has the bigger amplifier - 250W against 130W RMS, about 2.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Monitor Audio Vestra W10 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 | depends | Monitor Audio Vestra W10 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; OSD Nero DueVoce DualX8 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. |
| Cabinet size | depends | OSD Nero DueVoce DualX8 is about 40% 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 | Monitor Audio Vestra W10 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 | B | OSD Nero DueVoce DualX8 costs less - $300 against $979, about 69% less. |
A Monitor Audio Vestra W10 B OSD Nero DueVoce DualX8
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: Monitor Audio Vestra W10 measures better, OSD Nero DueVoce DualX8 costs about 69% 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, Monitor Audio Vestra W10 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 $979 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.
