In this review, we will be comparing RP-1400CSW and SB-3000 R|Evolution, two Powered Subwoofer speakers from Klipsch 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 Klipsch RP-1400CSW and SVS SB-3000 R|Evolution 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 Klipsch RP-1400CSWand SVS SB-3000 R|Evolution have a single woofer setup however the Klipsch RP-1400CSW's woofer is 14-inch whereas the SVS SB-3000 R|Evolution features a 13-inch woofer.
Frequency Response
RP-1400CSW has a frequency range of 15-180 Hz whereas SB-3000 R|Evolution has a frequency range of 17-230 Hz. With a minimum frequency of 15Hz, the RP-1400CSW can go slightly deeper then the SB-3000 R|Evolution's min frequency of 17Hz.
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
Both Klipsch RP-1400CSW and SVS SB-3000 R|Evolution have Acoustic Suspension type cabinets. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 Klipsch RP-1400CSW's and SVS SB-3000 R|Evolution's external dimensions. Klipsch RP-1400CSW has external dimensions of 444.0 x 421.6 x 421.6mm (17.48inch x 16.6inch x 16.6inch) whereas SVS SB-3000 R|Evolution has external dimensions of 396.0 x 386.0 x 427.0mm (15-9/16 x 15-3/16 x 16-13/16inch).
SVS SB-3000 R|Evolution is 35.6mm narrower and 48mm shorter than Klipsch RP-1400CSW but it is also 5.4mm deeper.
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.
Near-identical footprints. Klipsch RP-1400CSW is 48mm 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 Klipsch RP-1400CSW is approximately 1777.5cm2 / 275.5inch2 and base area of the SVS SB-3000 R|Evolution is approximately 1648.2cm2 / 255.5inch2. The RP-1400CSW requires 8% more surface area than the SB-3000 R|Evolution which gives it a small disadvantage on placement in tight spaces.
