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.
In the following sections, we will get into details in order to better understand how the Q Acoustics Q SUB80 and SVS PB-1000 compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

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.

Ported designs are generally more efficient than the Sealed designs.
Physical Specs
Size of a speaker can sometimes become 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.
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.
