In this review, we will be comparing PB-3000 R|Evolution and R-101SW, two Powered Subwoofer speakers from SVS 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 SVS PB-3000 R|Evolution and Klipsch R-101SW 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 SVS PB-3000 R|Evolutionand Klipsch R-101SW have a single woofer setup however the SVS PB-3000 R|Evolution's woofer is 13-inch whereas the Klipsch R-101SW features a 10-inch woofer.
Frequency Response
PB-3000 R|Evolution has a frequency range of 16-235 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 16Hz, the PB-3000 R|Evolution can go significantly deeper on the low side and provide stronger bass compared to the R-101SW's min frequency of 30Hz.
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.

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-3000 R|Evolution's and Klipsch R-101SW's external dimensions. SVS PB-3000 R|Evolution has external dimensions of 556.0 x 465.0 x 627.0mm (21-7/8 x 18-5/16 x 24-11/16inch) whereas Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm (14-9/16inch x 14-1/16inch x 20-13/16inch).
SVS PB-3000 R|Evolution is clearly the larger of the two speakers. Its body is 107mm wider, 186mm taller and 98mm deeper than Klipsch R-101SW.
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-3000 R|Evolution is approximately 2915.6cm2 / 451.9inch2 and base area of the Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The PB-3000 R|Evolution requires 54% more surface area than the R-101SW which gives it a small disadvantage on placement in tight spaces.
