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 Cambridge Audio Minx X301 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's and Cambridge Audio Minx X301'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 Cambridge Audio Minx X301 has external dimensions of 312.0 x 267.0 x 310.0mm ( 12-1/4 x 10-1/2 x 12-3/16inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 114mm wider, 168mm taller and 222mm deeper than Cambridge Audio Minx X301.

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 Cambridge Audio Minx X301 is approximately 827.7cm2 / 128.3inch2. The PB-1000 requires 145% more surface area than the Minx X301 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 Cambridge Audio Minx X301 weighs 7.50kg / 16.5lbs. This makes the PB-1000 179% heavier than the Minx X301.
