In this review, we will be comparing SB-4000 and SB-3000 R|Evolution, two Powered Subwoofer speakers by 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 SVS SB-4000 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 SVS SB-4000and SVS SB-3000 R|Evolution have a single woofer setup however the SVS SB-4000's woofer is 13.5-inch whereas the SVS SB-3000 R|Evolution features a 13-inch woofer.
Frequency Response
SB-4000 has a frequency range of 19-310 Hz whereas SB-3000 R|Evolution has a frequency range of 17-230 Hz. With a minimum frequency of 17Hz, the SB-3000 R|Evolution can go slightly deeper then the SB-4000's min frequency of 19Hz.
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 SVS SB-4000 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 SVS SB-4000's and SVS SB-3000 R|Evolution's external dimensions. SVS SB-4000 has external dimensions of 466.0 x 453.0 x 532.0mm (18-5/16 x 17-13/16 x 20-15/16inch) 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-4000 is clearly the larger of the two speakers. Its body is 67mm wider, 70mm taller and 105mm deeper than SVS SB-3000 R|Evolution.
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 SB-4000 is approximately 2410.0cm2 / 373.6inch2 and base area of the SVS SB-3000 R|Evolution is approximately 1648.2cm2 / 255.5inch2. The SB-4000 requires 46% more surface area than the SB-3000 R|Evolution which gives it a small disadvantage on placement in tight spaces.
