In this review, we will be comparing RP-1600SW and KC62, 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 RP-1600SW and KEF KC62 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 RP-1600SW and KEF KC62 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 RP-1600SW and KEF KC62 have a totally different setup: the Klipsch RP-1600SW features 1 x 16-inch drivers whereas the KC62 features 2 x 6.5-inch drivers.
Frequency Response
RP-1600SW has a frequency range of 14.5-175 Hz whereas KC62 has a frequency range of 11-200 Hz. With a minimum frequency of 11Hz, the KC62 can go slightly deeper then the RP-1600SW's min frequency of 15Hz.
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 RP-1600SW 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 KC62 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 RP-1600SW's and KEF KC62's external dimensions. Klipsch RP-1600SW has external dimensions of 596.0 x 597.0 x 696.0mm ( 23-7/16inch x 23-1/2inch x 27-3/8inch ) whereas 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 ) .
Klipsch RP-1600SW is clearly the larger of the two speakers. Its body is 339mm wider, 351mm taller and 415mm deeper than KEF KC62.

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 RP-1600SW is approximately 4155.1cm2 / 644.0inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The RP-1600SW requires 473% more surface area than the KC62 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 RP-1600SW weighs 50.00kg / 110lbs and the KEF KC62 weighs 14.05kg / 30.9lbs. This makes the RP-1600SW 256% heavier than the KC62.
