Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both Wharfedale SW-15and Wharfedale SW-12 have a single woofer setup however the Wharfedale SW-15's woofer is 15-inch whereas the Wharfedale SW-12 features a 12-inch woofer.

Physical Specs
The size of a speaker can sometimes be 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 Wharfedale SW-12'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 Wharfedale SW-12 has external dimensions of 480.0 x 402.0 x 512.0mm (18-7/8inch x 15-13/16inch x 20-1/8inch).
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 91mm wider, 90mm taller and 103mm deeper than Wharfedale SW-12.
Below you can see the front view size comparison of Wharfedale SW-15 and Wharfedale SW-12 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 Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2 and base area of the Wharfedale SW-12 is approximately 2058.2cm2 / 319.0inch2. The SW-15 requires 47% more surface area than the SW-12 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 Wharfedale SW-12 weighs 21.54kg / 47.4lbs. This makes the SW-15 47% heavier than the SW-12.
