In this review, we will be comparing Q SUB120 and PC-2000, 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 SUB120 and SVS PC-2000 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 SUB120 and SVS PC-2000 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.Q Acoustics Q SUB120and SVS PC-2000 have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Q SUB120 has a frequency range of 28-250 Hz whereas PC-2000 has a frequency range of 16-260 Hz. With a minimum frequency of 16Hz, the PC-2000 can go significantly deeper on the low side and provide stronger bass compared to the Q SUB120'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.

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 SUB120's and SVS PC-2000's external dimensions. Q Acoustics Q SUB120 has external dimensions of 400.0 x 400.0 x 432.0mm ( 15-3/4 x 15-3/4 x 17inch) whereas SVS PC-2000 has external dimensions of 872.0 x 422.0 x 422.0mm ( 34-5/16 x 16-5/8 x 16-5/8inch) .
Q Acoustics Q SUB120 is 22mm narrower and 472mm shorter than SVS PC-2000 but it is also 10mm deeper.
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 SUB120 is approximately 1728.0cm2 / 267.8inch2 and base area of the SVS PC-2000 is approximately 1780.8cm2 / 276.0inch2. The Q SUB120 requires 3% less surface area than the PC-2000 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 SUB120 weighs 22.50kg / 49.5lbs and the SVS PC-2000 weighs 22.70kg / 49.9lbs. This makes the PC-2000 1% heavier than the Q SUB120.
Here is a comparison of how Q SUB120 and PC-2000's weights compare with the average, max and min weights in Powered Subwoofer class.
