In this review, we will be comparing Q SUB120 and SPL-100, two Powered Subwoofer speakers from Q Acoustics and Klipsch. 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 Klipsch SPL-100 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 Klipsch SPL-100 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 SUB120and Klipsch SPL-100 have a single woofer setup however the Q Acoustics Q SUB120's woofer is 12-inch whereas the Klipsch SPL-100 features a 10-inch woofer.
Frequency Response
Q SUB120 has a frequency range of 28-250 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 27Hz, the SPL-100 can go slightly deeper then 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 Klipsch SPL-100'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 Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm ( 16-7/16 x 14-1/16 x 18-13/16inch) .
Q Acoustics Q SUB120 is 18mm shorter and 46mm less deeper than Klipsch SPL-100 but it is also 42mm wider.
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 Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Q SUB120 requires 1% more surface area than the SPL-100 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 Q Acoustics Q SUB120 weighs 22.50kg / 49.5lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the Q SUB120 34% heavier than the SPL-100.
Here is a comparison of how Q SUB120 and SPL-100's weights compare with the average, max and min weights in Powered Subwoofer class.
