In this review, we will be comparing WH S8E and KUBE 8b, two Powered Subwoofer speakers from Wharfedale and KEF. 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 WH-S8E and KEF KUBE 8b first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Wharfedale WH-S8E and KEF KUBE 8b compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Wharfedale WH-S8Eand KEF KUBE 8b have the same driver set up: Both subwoofers have 1 x 8" drivers.
Frequency Response
WH S8E has a frequency range of 40-200 Hz whereas KUBE 8b has a frequency range of 34-140 Hz. With a minimum frequency of 34Hz, the KUBE 8b can go significantly deeper on the low side and provide stronger bass compared to the WH S8E's min frequency of 40Hz.
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 WH-S8E 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 KEF KUBE 8b 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
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 WH-S8E's and KEF KUBE 8b's external dimensions. Wharfedale WH-S8E has external dimensions of 330.0 x 268.0 x 327.0mm ( 13 x 10-9/16 x 12-7/8inch) whereas KEF KUBE 8b has external dimensions of 294.0 x 296.0 x 339.0mm ( 11-9/16 x 11-5/8 x 13-5/16inch) .
Wharfedale WH-S8E is 28mm narrower and 12mm less deeper than KEF KUBE 8b but it is also 36mm taller.
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 WH-S8E is approximately 876.4cm2 / 135.8inch2 and base area of the KEF KUBE 8b is approximately 1003.4cm2 / 155.5inch2. The WH S8E requires 13% less surface area than the KUBE 8b 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 Wharfedale WH-S8E weighs 8.20kg / 18lbs and the KEF KUBE 8b weighs 11.36kg / 25lbs. This makes the KUBE 8b 39% heavier than the WH S8E.
Here is a comparison of how WH S8E and KUBE 8b's weights compare with the average, max and min weights in Powered Subwoofer class.
