In this review, we will be comparing Stage 220P and R-121SW, two Powered Subwoofer speakers from JBL 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 JBL Stage 220P and Klipsch R-121SW first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the JBL Stage 220P and Klipsch R-121SW 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.JBL Stage 220P and Klipsch R-121SW have a totally different setup: the JBL Stage 220P features x 12-inch drivers whereas the R-121SW features 1 x 12-inch drivers.
Frequency Response
Stage 220P has a frequency range of 29-150 Hz whereas R-121SW has a frequency range of 28-120 Hz. With a minimum frequency of 28Hz, the R-121SW can go slightly deeper then the Stage 220P's min frequency of 29Hz.
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 JBL Stage 220P 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 Klipsch R-121SW 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 JBL Stage 220P's and Klipsch R-121SW's external dimensions. JBL Stage 220P has external dimensions of 418.0 x 405.0 x 445.0mm ( 16-7/16inch x 15-15/16inch x 17-1/2inch ) whereas Klipsch R-121SW has external dimensions of 423.0 x 407.0 x 532.0mm ( 16-5/8inch x 16inch x 20-15/16inch ) .
Klipsch R-121SW is clearly the larger of the two speakers. Its body is 2mm wider, 5mm taller and 87mm deeper than JBL Stage 220P.
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 JBL Stage 220P is approximately 1802.3cm2 / 279.4inch2 and base area of the Klipsch R-121SW is approximately 2165.2cm2 / 335.6inch2. The Stage 220P requires 17% less surface area than the R-121SW 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 JBL Stage 220P weighs 18.73kg / 41.2lbs and the Klipsch R-121SW weighs 16.00kg / 35.2lbs. This makes the Stage 220P 17% heavier than the R-121SW.
Here is a comparison of how Stage 220P and R-121SW's weights compare with the average, max and min weights in Powered Subwoofer class.
