In this review, we will be comparing SB-4000 and SB-1000 Pro, 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-1000 Pro first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the SVS SB-4000 and SVS SB-1000 Pro 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 SVS SB-4000and SVS SB-1000 Pro have a single woofer setup however the SVS SB-4000's woofer is 13.5-inch whereas the SVS SB-1000 Pro features a 12-inch woofer.
Frequency Response
SB-4000 has a frequency range of 19-310 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 19Hz, the SB-4000 can go slightly deeper then the SB-1000 Pro's min frequency of 20Hz.
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-1000 Pro have Acoustic Suspension type cabinets.

Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 SVS SB-4000's and SVS SB-1000 Pro'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-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm ( 13-1/2inch x 13inch x 15-13/16inch ) .
SVS SB-4000 is clearly the larger of the two speakers. Its body is 122mm wider, 123mm taller and 130mm deeper than SVS SB-1000 Pro.
Below you can see the front view size comparison of SVS SB-4000 and SVS SB-1000 Pro in scale.

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-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The SB-4000 requires 81% more surface area than the SB-1000 Pro 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 SVS SB-4000 weighs 46.50kg / 102.3lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the SB-4000 293% heavier than the SB-1000 Pro.
Here is a comparison of how SB-4000 and SB-1000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.
