Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.GoldenEar SuperSub X and Wharfedale SW-15 have a totally different setup: the GoldenEar SuperSub X features 2 x 8-inch drivers whereas the SW-15 features 1 x 15-inch drivers.
Frequency Response
SuperSub X has a frequency range of 12-250 Hz whereas SW-15 has a frequency range of 30-120 Hz. With a minimum frequency of 12Hz, the SuperSub X can go significantly deeper on the low side and provide stronger bass compared to the SW-15'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 GoldenEar SuperSub X has a Passive Radiator type cabinet. 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. On the other hand the Wharfedale SW-15 have Bass Reflex type enclosure. 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.

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 GoldenEar SuperSub X's and Wharfedale SW-15's external dimensions. GoldenEar SuperSub X has external dimensions of 324.0 x 356.0 x 388.0mm ( 12-3/4inch x 14inch x 15-1/4inch ) whereas 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 ) .
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 137mm wider, 246mm taller and 227mm deeper than GoldenEar SuperSub X.

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 GoldenEar SuperSub X is approximately 1381.3cm2 / 214.1inch2 and base area of the Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2. The SuperSub X requires 54% less surface area than the SW-15 which gives it a small advantage 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 GoldenEar SuperSub X weighs 18.18kg / 40lbs and the Wharfedale SW-15 weighs 31.57kg / 69.5lbs. This makes the SW-15 74% heavier than the SuperSub X.
