In this review, we will be comparing PB-2000 Pro and SubSeries 350, two Powered Subwoofer speakers from SVS 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 SVS PB-2000 Pro and PSB SubSeries 350 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.SVS PB-2000 Proand PSB SubSeries 350 have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
PB-2000 Pro has a frequency range of 16-290 Hz whereas SubSeries 350 has a frequency range of 25-150 Hz. With a minimum frequency of 16Hz, the PB-2000 Pro can go significantly deeper on the low side and provide stronger bass compared to the SubSeries 350's min frequency of 25Hz.
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.

Cabinet Type
The SVS PB-2000 Pro has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the PSB SubSeries 350 have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
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 SVS PB-2000 Pro's and PSB SubSeries 350's external dimensions. SVS PB-2000 Pro has external dimensions of 534.0 x 442.0 x 609.0mm (21 x 17-3/8 x 23-15/16inch) whereas PSB SubSeries 350 has external dimensions of 407.0 x 394.0 x 445.0mm (16 x 15-1/2 x 17-1/2inch).
SVS PB-2000 Pro is clearly the larger of the two speakers. Its body is 48mm wider, 127mm taller and 164mm deeper than PSB SubSeries 350.

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 SVS PB-2000 Pro is approximately 2691.8cm2 / 417.2inch2 and base area of the PSB SubSeries 350 is approximately 1753.3cm2 / 271.8inch2. The PB-2000 Pro requires 54% more surface area than the SubSeries 350 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 SVS PB-2000 Pro weighs 29.45kg / 64.8lbs and the PSB SubSeries 350 weighs 23.18kg / 51lbs. This makes the PB-2000 Pro 27% heavier than the SubSeries 350.
Here is a comparison of how PB-2000 Pro and SubSeries 350'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.
SVS PB-2000 Pro needs about 54% more floor area. SVS PB-2000 Pro stands 164mm further into the room. SVS PB-2000 Pro is 127mm taller.

A ported 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 | SVS PB-2000 Pro goes deeper - 16Hz against 25Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS PB-2000 Pro has the bigger amplifier - 550W against 300W RMS, about 2.6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | SVS PB-2000 Pro is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; PSB SubSeries 350 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. |
| Speaker-level inputs | B | PSB SubSeries 350 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | PSB SubSeries 350 is about 50% 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 | SVS PB-2000 Pro carries 5 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 | SVS PB-2000 Pro costs less - $1,100 against $1,299, about 15% less. |
A SVS PB-2000 Pro B PSB SubSeries 350
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?
SVS PB-2000 Pro is the easier recommendation: it leads on most of the measured areas and costs less. Take PSB SubSeries 350 if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, SVS PB-2000 Pro will hit harder for the money; if it is mainly for music in a normal-sized room, PSB SubSeries 350 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, PSB SubSeries 350 is the only one of these two you can connect at all.
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.
