In this review, we will be comparing RW-100SW and KUBE 10b, two Powered Subwoofer speakers from Klipsch 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 Klipsch RW-100SW and KEF KUBE 10b first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Klipsch RW-100SW and KEF KUBE 10b 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.Klipsch RW-100SWand KEF KUBE 10b have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
RW-100SW has a frequency range of 27-125 Hz whereas KUBE 10b has a frequency range of 24-140 Hz. With a minimum frequency of 24Hz, the KUBE 10b can go slightly deeper then 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 Klipsch RW-100SW 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 10b 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 Klipsch RW-100SW's and KEF KUBE 10b's external dimensions. 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 ) whereas KEF KUBE 10b has external dimensions of 372.0 x 356.0 x 397.0mm ( 14-5/8 x 14 x 15-5/8inch) .
Klipsch RW-100SW is clearly the larger of the two speakers. Its body is 27mm wider, 11mm taller and 75mm deeper than KEF KUBE 10b.
Below you can see the front view size comparison of Klipsch RW-100SW and KEF KUBE 10b 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 Klipsch RW-100SW is approximately 1807.8cm2 / 280.2inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The RW-100SW requires 28% more surface area than the KUBE 10b 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 Klipsch RW-100SW weighs 17.73kg / 39lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the RW-100SW 1% heavier than the KUBE 10b.
Here is a comparison of how RW-100SW and KUBE 10b's weights compare with the average, max and min weights in Powered Subwoofer class.
