In this review, we will be comparing WH S10E and SPL-120, two Powered Subwoofer speakers from Wharfedale and Klipsch. 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-S10E and Klipsch SPL-120 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-S10E and Klipsch SPL-120 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.Both Wharfedale WH-S10Eand Klipsch SPL-120 have a single woofer setup however the Wharfedale WH-S10E's woofer is 10-inch whereas the Klipsch SPL-120 features a 12-inch woofer.
Frequency Response
WH S10E has a frequency range of 35-120 Hz whereas SPL-120 has a frequency range of 24-125 Hz. With a minimum frequency of 24Hz, the SPL-120 can go significantly deeper on the low side and provide stronger bass compared to the WH S10E's min frequency of 35Hz.
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-S10E has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch SPL-120 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 Wharfedale WH-S10E's and Klipsch SPL-120's external dimensions. Wharfedale WH-S10E has external dimensions of 394.0 x 333.0 x 397.0mm ( 15-1/2 x 13-1/8 x 15-5/8inch) whereas Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm ( 17-11/16 x 14-3/4 x 21-1/4inch) .
Klipsch SPL-120 is clearly the larger of the two speakers. Its body is 42mm wider, 56mm taller and 143mm deeper than Wharfedale WH-S10E.
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-S10E is approximately 1322.0cm2 / 204.9inch2 and base area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2. The WH S10E requires 35% less surface area than the SPL-120 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-S10E weighs 14.40kg / 31.7lbs and the Klipsch SPL-120 weighs 20.45kg / 45lbs. This makes the SPL-120 42% heavier than the WH S10E.
Here is a comparison of how WH S10E and SPL-120's weights compare with the average, max and min weights in Powered Subwoofer class.
