In this review, we will be comparing SB-1000 Pro and SubSeries 450, 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 SB-1000 Pro and PSB SubSeries 450 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 SB-1000 Proand PSB SubSeries 450 have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
SB-1000 Pro has a frequency range of 20-270 Hz whereas SubSeries 450 has a frequency range of 20-150 Hz.
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 SB-1000 Pro has a Acoustic Suspension type cabinet. 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. On the other hand the PSB SubSeries 450 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed 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 SB-1000 Pro's and PSB SubSeries 450's external dimensions. SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch) whereas PSB SubSeries 450 has external dimensions of 401.0 x 413.0 x 453.0mm (15-3/4 x 16-1/4 x 17-13/16inch).
PSB SubSeries 450 is clearly the larger of the two speakers. Its body is 82mm wider, 58mm taller and 51mm deeper than SVS SB-1000 Pro.
Below you can see the front view size comparison of SVS SB-1000 Pro and PSB SubSeries 450 in scale.

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 SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2 and base area of the PSB SubSeries 450 is approximately 1870.9cm2 / 290.0inch2. The SB-1000 Pro requires 29% less surface area than the SubSeries 450 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 SVS SB-1000 Pro weighs 11.82kg / 26lbs and the PSB SubSeries 450 weighs 20.45kg / 45lbs. This makes the SubSeries 450 73% heavier than the SB-1000 Pro.
Here is a comparison of how SB-1000 Pro and SubSeries 450'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.
PSB SubSeries 450 needs about 41% more floor area. PSB SubSeries 450 stands 51mm further into the room. PSB SubSeries 450 is 58mm 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 (20Hz vs 20Hz). |
| Amplifier power | evenly matched | Much the same amplifier (325W vs 400W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | SVS SB-1000 Pro is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; PSB SubSeries 450 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. |
| Wireless option | depends | Only SVS SB-1000 Pro offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Cabinet size | depends | SVS SB-1000 Pro is about 39% 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 SB-1000 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 SB-1000 Pro costs less - $600 against $1,999, about 70% less. |
A SVS SB-1000 Pro B PSB SubSeries 450
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 SB-1000 Pro has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, PSB SubSeries 450 will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-1000 Pro 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 $600 each, two SVS SB-1000 Pro cost about $1,200 against $1,999 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.
