In this review, we will be comparing Q SUB80 and PB-1000, two Powered Subwoofer speakers from Q Acoustics and SVS. 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 Q Acoustics Q SUB80 and SVS PB-1000 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 Q Acoustics Q SUB80and SVS PB-1000 have a single woofer setup however the Q Acoustics Q SUB80's woofer is 8-inch whereas the SVS PB-1000 features a 10-inch woofer.
Frequency Response
Q SUB80 has a frequency range of 36-250 Hz whereas PB-1000 has a frequency range of 19-270 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 Q SUB80's min frequency of 36Hz.
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 Q Acoustics Q SUB80 has a Infinite Baffle type cabinet. On the other hand the SVS PB-1000 have Bass Reflex type enclosure. 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 Q Acoustics Q SUB80's and SVS PB-1000's external dimensions. Q Acoustics Q SUB80 has external dimensions of 315.0 x 315.0 x 347.0mm (12-3/8 x 12-3/8 x 13-11/16inch) whereas SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch).
SVS PB-1000 is clearly the larger of the two speakers. Its body is 66mm wider, 165mm taller and 185mm deeper than Q Acoustics Q SUB80.
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.
SVS PB-1000 needs about 85% more floor or shelf area. SVS PB-1000 is 185mm deeper, so it stands that much further out from the wall. SVS PB-1000 is 165mm 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 Q Acoustics Q SUB80 is approximately 1093.1cm2 / 169.4inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The Q SUB80 requires 46% less surface area than the PB-1000 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 Q Acoustics Q SUB80 weighs 15.00kg / 33lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 39% heavier than the Q SUB80.
Here is a comparison of how Q SUB80 and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed subwoofer against a ported 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 | B | SVS PB-1000 goes deeper - 19Hz against 36Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS PB-1000 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS PB-1000 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 | Q Acoustics Q SUB80 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; SVS PB-1000 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. 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 | Q Acoustics Q SUB80 is about 65% 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. |
| Price | B | SVS PB-1000 costs less - $499 against $599, about 17% less. |
A Q Acoustics Q SUB80 B SVS PB-1000
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 Q Acoustics Q SUB80 if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, SVS PB-1000 will hit harder for the money; if it is mainly for music in a normal-sized room, Q Acoustics Q SUB80 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - Q Acoustics Q SUB80 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.
