In this review, we will be comparing SW-15 and Sub 6, two Powered Subwoofer speakers from Wharfedale and Dynaudio. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Wharfedale SW-15 and Dynaudio Sub 6 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.

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 Dynaudio Sub 6 have a single woofer setup however the Wharfedale SW-15's woofer is 15-inch whereas the Dynaudio Sub 6 features a 9.5-inch woofer.
Frequency Response
SW-15 has a frequency range of 30-120 Hz whereas Sub 6 has a frequency range of 16-230 Hz. With a minimum frequency of 16Hz, the Sub 6 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 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 Dynaudio Sub 6 have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 Wharfedale SW-15's and Dynaudio Sub 6'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 Dynaudio Sub 6 has external dimensions of 334.0 x 477.0 x 312.0mm (13-1/8 x 18-3/4 x 12-1/4inch).
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 16mm wider, 236mm taller and 303mm deeper than Dynaudio Sub 6.
Below you can see the front view size comparison of Wharfedale SW-15 and Dynaudio Sub 6 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 Dynaudio Sub 6 is approximately 1488.2cm2 / 230.7inch2. The SW-15 requires 104% more surface area than the Sub 6 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 Dynaudio Sub 6 weighs 20.55kg / 45.2lbs. This makes the SW-15 54% heavier than the Sub 6.
Here is a comparison of how SW-15 and Sub 6's weights compare with the average, max and min weights in Powered Subwoofer class.
