Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both SVS PB-1000 Proand Monitor Audio Radius 380 have a single woofer setup however the SVS PB-1000 Pro's woofer is 12-inch whereas the Monitor Audio Radius 380 features a 8-inch woofer.
Frequency Response
PB-1000 Pro has a frequency range of 17-260 Hz whereas Radius 380 has a frequency range of 30-120 Hz. With a minimum frequency of 17Hz, the PB-1000 Pro can go significantly deeper on the low side and provide stronger bass compared to the Radius 380'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.

Cabinet Type
The SVS PB-1000 Pro 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 Radius 380 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed 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 Pro's and Monitor Audio Radius 380's external dimensions. SVS PB-1000 Pro has external dimensions of 479.0 x 380.0 x 509.0mm ( 18-13/16inch x 15inch x 20-15/16inch ) whereas Monitor Audio Radius 380 has external dimensions of 308.0 x 291.0 x 345.0mm ( 12-1/8 x 11-7/16 x 13-9/16inch) .
SVS PB-1000 Pro is clearly the larger of the two speakers. Its body is 89mm wider, 171mm taller and 164mm deeper than Monitor Audio Radius 380.
Below you can see the front view size comparison of SVS PB-1000 Pro and Monitor Audio Radius 380 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 PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2 and base area of the Monitor Audio Radius 380 is approximately 1004.0cm2 / 155.6inch2. The PB-1000 Pro requires 93% more surface area than the Radius 380 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 Pro weighs 19.30kg / 42.5lbs and the Monitor Audio Radius 380 weighs 10.18kg / 22.4lbs. This makes the PB-1000 Pro 90% heavier than the Radius 380.
Here is a comparison of how PB-1000 Pro and Radius 380's weights compare with the average, max and min weights in Powered Subwoofer class.
