The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both Wharfedale SW-15and Definitive ProSub 1000 have a single woofer setup however the Wharfedale SW-15's woofer is 15-inch whereas the Definitive ProSub 1000 features a 10-inch woofer.

Cabinet Type
The Wharfedale SW-15 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 Definitive ProSub 1000 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 Wharfedale SW-15's and Definitive ProSub 1000's external dimensions. Wharfedale SW-15 has external dimensions of 570.0 x 493.0 x 615.0mm ( 22-7/16inch x 19-3/8inch x 24-3/16inch ) whereas Definitive ProSub 1000 has external dimensions of 366.0 x 307.0 x 486.0mm ( 14-3/8 x 12-1/16 x 19-1/8inch) .
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 186mm wider, 204mm taller and 129mm deeper than Definitive ProSub 1000.
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 Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2 and base area of the Definitive ProSub 1000 is approximately 1492.0cm2 / 231.3inch2. The SW-15 requires 103% more surface area than the ProSub 1000 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 Wharfedale SW-15 weighs 31.57kg / 69.5lbs and the Definitive ProSub 1000 weighs 14.09kg / 31lbs. This makes the SW-15 124% heavier than the ProSub 1000.
Here is a comparison of how SW-15 and ProSub 1000's weights compare with the average, max and min weights in Powered Subwoofer class.
