In this review, we will be comparing PB-1000 and Alpha S10, 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-1000 and PSB Alpha S10 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-1000and PSB Alpha S10 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas Alpha S10 has a frequency range of 28-150 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the Alpha S10's min frequency of 28Hz.
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
Both SVS PB-1000 and PSB Alpha S10 have Bass Reflex type cabinets. 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.
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-1000's and PSB Alpha S10's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch) whereas PSB Alpha S10 has external dimensions of 358.0 x 358.0 x 472.0mm (14-1/16 x 14-1/16 x 18-9/16inch).
SVS PB-1000 is clearly the larger of the two speakers. Its body is 23mm wider, 122mm taller and 60mm deeper than PSB Alpha S10.
Below you can see the front view size comparison of SVS PB-1000 and PSB Alpha S10 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 PB-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the PSB Alpha S10 is approximately 1689.8cm2 / 261.9inch2. The PB-1000 requires 20% more surface area than the Alpha S10 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-1000 weighs 20.91kg / 46lbs and the PSB Alpha S10 weighs 13.64kg / 30lbs. This makes the PB-1000 53% heavier than the Alpha S10.
Here is a comparison of how PB-1000 and Alpha S10'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-1000 needs about 20% more floor area. SVS PB-1000 stands 60mm further into the room. SVS PB-1000 is 122mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | A | SVS PB-1000 goes deeper - 19Hz against 28Hz. 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-1000 has the bigger amplifier - 300W against 150W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Speaker-level inputs | A | SVS PB-1000 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 Alpha S10 is about 38% 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-1000 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-1000 costs less - $499 against $699, about 29% less. |
A SVS PB-1000 B PSB Alpha S10
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-1000 is the easier recommendation: it leads on most of the measured areas and costs less. Take PSB Alpha S10 if one of the "depends" rows describes your room. Check your amplifier first: if it has no subwoofer or preamp output, SVS PB-1000 is the only one of these two you can connect at all. If placement is the constraint - a corner, behind a sofa, under a desk - PSB Alpha S10 is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
