Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Tannoy iW 62TS and Wilson Audio Subsonic have a totally different setup: the Tannoy iW 62TS features x -inch drivers whereas the Subsonic features 3 x 12-inch drivers.
Frequency Response
iW 62TS has a frequency range of whereas Subsonic has a frequency range of 10-150 Hz. With a minimum frequency of Hz, the iW 62TS can go significantly deeper on the low side and provide stronger bass compared to the Subsonic's min frequency of 10Hz.
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.

Input Type and Bi-Amping / Bi-Wiring
iW 62TS features Binding post type posts and Subsonic has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type
Both Tannoy iW 62TS and Wilson Audio Subsonic have Bass Reflex type cabinets. 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
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 Tannoy iW 62TS's and Wilson Audio Subsonic's external dimensions. Tannoy iW 62TS has external dimensions of () whereas Wilson Audio Subsonic has external dimensions of 1653.0 x 459.0 x 691.0mm (65-1/16 x 18-1/16 x 27-3/16inch).
Wilson Audio Subsonic is clearly the larger of the two speakers. Its body is 459mm wider, 1653mm taller and 691mm deeper than Tannoy iW 62TS.
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 Tannoy iW 62TS weighs 7.39kg / 16.3lbs and the Wilson Audio Subsonic weighs 229.00kg / 503.8lbs. This makes the Subsonic 2,999% heavier than the iW 62TS.
Here is a comparison of how iW 62TS and Subsonic's weights compare with the average, max and min weights in Passive Subwoofer class.
