In this review, we will be comparing Nero DueVoce DualX8 and SubSeries 150, two Powered Subwoofer speakers from OSD and PSB. 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 PSB SubSeries 150 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 PSB SubSeries 150 have a single woofer setup however the OSD Nero DueVoce DualX8's woofer is 8-inch whereas the PSB SubSeries 150 features a 6.5-inch woofer.
Frequency Response
Nero DueVoce DualX8 has a frequency range of 17-165 Hz whereas SubSeries 150 has a frequency range of 26-150 Hz. With a minimum frequency of 17Hz, the Nero DueVoce DualX8 can go significantly deeper on the low side and provide stronger bass compared to the SubSeries 150's min frequency of 26Hz.
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 PSB SubSeries 150's external dimensions. OSD Nero DueVoce DualX8 has external dimensions of 311.2 x 265.1 x 333.4mm () whereas PSB SubSeries 150 has external dimensions of 280.0 x 447.0 x 143.0mm (11 x 17-9/16 x 5-5/8inch).
PSB SubSeries 150 is 31.2mm shorter and 190.4mm less deeper than OSD Nero DueVoce DualX8 but it is also 181.9mm wider.
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.
OSD Nero DueVoce DualX8 needs about 38% more floor or shelf area. OSD Nero DueVoce DualX8 is 190mm deeper, so it stands that much further out from the wall. OSD Nero DueVoce DualX8 is 31mm taller.
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 PSB SubSeries 150 is approximately 639.2cm2 / 99.1inch2. The Nero DueVoce DualX8 requires 38% more surface area than the SubSeries 150 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 PSB SubSeries 150 weighs 6.05kg / 13.3lbs. This makes the Nero DueVoce DualX8 29% heavier than the SubSeries 150.
Here is a comparison of how Nero DueVoce DualX8 and SubSeries 150's weights compare with the average, max and min weights in Powered Subwoofer class.

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 26Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | OSD Nero DueVoce DualX8 has the bigger amplifier - 130W against 100W RMS, about 1.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | OSD Nero DueVoce DualX8 moves more air: 8" against 6.5" is 1.51x the cone area, not the 1.23x 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; PSB SubSeries 150 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. |
| Cabinet size | depends | PSB SubSeries 150 is about 35% 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 $499, about 40% less. |
A OSD Nero DueVoce DualX8 B PSB SubSeries 150
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?
OSD Nero DueVoce DualX8 is the easier recommendation: it leads on most of the measured areas and costs less. Take PSB SubSeries 150 if one of the "depends" rows describes your room. 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, PSB SubSeries 150 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 $499 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.
