The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both SVS PB-1000and Monitor Audio CW8 have a single woofer setup however the SVS PB-1000's woofer is 10-inch whereas the Monitor Audio CW8 features a 8-inch woofer.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas CW8 has a frequency range of 35-135 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the CW8's min frequency of 35Hz.
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
The SVS PB-1000 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the Monitor Audio CW8 have Acoustic Suspension type enclosure. 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
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 PB-1000's and Monitor Audio CW8's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) whereas Monitor Audio CW8 has external dimensions of 274.0 x 262.0 x 326.0mm ( 10-3/4 x 10-5/16 x 12-13/16inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 119mm wider, 206mm taller and 206mm deeper than Monitor Audio CW8.
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-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the Monitor Audio CW8 is approximately 854.1cm2 / 132.4inch2. The PB-1000 requires 137% more surface area than the CW8 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 PB-1000 weighs 20.91kg / 46lbs and the Monitor Audio CW8 weighs 9.55kg / 21lbs. This makes the PB-1000 119% heavier than the CW8.
Here is a comparison of how PB-1000 and CW8's weights compare with the average, max and min weights in Powered Subwoofer class.
