In this review, we will be comparing KC62 and RW-100SW, two Powered Subwoofer speakers from KEF 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 KEF KC62 and Klipsch RW-100SW first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the KEF KC62 and Klipsch RW-100SW 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.KEF KC62 and Klipsch RW-100SW have a totally different setup: the KEF KC62 features 2 x 6.5-inch drivers whereas the RW-100SW features 1 x 10-inch drivers.
Frequency Response
KC62 has a frequency range of 11-200 Hz whereas RW-100SW has a frequency range of 27-125 Hz. With a minimum frequency of 11Hz, the KC62 can go significantly deeper on the low side and provide stronger bass compared to the RW-100SW's min frequency of 27Hz.
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 KEF KC62 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 RW-100SW 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 KEF KC62's and Klipsch RW-100SW's external dimensions. KEF KC62 has external dimensions of 245.0 x 258.0 x 281.0mm ( 9-5/8inch x 10-1/8inch x 11-1/16inch ) whereas Klipsch RW-100SW has external dimensions of 383.0 x 383.0 x 472.0mm ( 15-1/16inch x 15-1/16inch x 18-9/16inch ) .
Klipsch RW-100SW is clearly the larger of the two speakers. Its body is 125mm wider, 138mm taller and 191mm deeper than KEF KC62.
Below you can see the front view size comparison of KEF KC62 and Klipsch RW-100SW 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 KEF KC62 is approximately 725.0cm2 / 112.4inch2 and base area of the Klipsch RW-100SW is approximately 1807.8cm2 / 280.2inch2. The KC62 requires 60% less surface area than the RW-100SW 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 KEF KC62 weighs 14.05kg / 30.9lbs and the Klipsch RW-100SW weighs 17.73kg / 39lbs. This makes the RW-100SW 26% heavier than the KC62.
Here is a comparison of how KC62 and RW-100SW's weights compare with the average, max and min weights in Powered Subwoofer class.
