In this review, we will be comparing C-308ASWi and ASW610, two Powered Subwoofer speakers from Klipsch and Bowers Wilkins. 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 C-308ASWi and B&W ASW610 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 C-308ASWi and B&W ASW610 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 Klipsch C-308ASWiand B&W ASW610 have a single woofer setup however the Klipsch C-308ASWi's woofer is 8-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
C-308ASWi has a frequency range of 28-150 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 27Hz, the ASW610 can go slightly deeper then the C-308ASWi's min frequency of 28Hz.
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 C-308ASWi has a Passive Radiator type cabinet. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs. On the other hand the B&W ASW610 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 C-308ASWi's and B&W ASW610's external dimensions. Klipsch C-308ASWi has external dimensions of 299.0 x 286.0 x 356.0mm ( 11-3/4 x 11-1/4 x 14inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm ( 12-5/8 x 12-1/4 x 15-1/2inch) .
B&W ASW610 is clearly the larger of the two speakers. Its body is 26mm wider, 22mm taller and 38mm deeper than Klipsch C-308ASWi.
Below you can see the front view size comparison of Klipsch C-308ASWi and B&W ASW610 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 C-308ASWi is approximately 1018.2cm2 / 157.8inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The C-308ASWi requires 17% less surface area than the ASW610 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 Klipsch C-308ASWi weighs 12.27kg / 27lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the ASW610 2% heavier than the C-308ASWi.
