In this review, we will be comparing Stage 200P and SPL-120, 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 200P and Klipsch SPL-120 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 200P and Klipsch SPL-120 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 200P and Klipsch SPL-120 have a totally different setup: the JBL Stage 200P features x 10-inch drivers whereas the SPL-120 features 1 x 12-inch drivers.
Frequency Response
Stage 200P has a frequency range of 32-150 Hz whereas SPL-120 has a frequency range of 24-125 Hz. With a minimum frequency of 24Hz, the SPL-120 can go significantly deeper on the low side and provide stronger bass compared to the Stage 200P's min frequency of 32Hz.
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 200P 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 SPL-120 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 200P's and Klipsch SPL-120's external dimensions. JBL Stage 200P has external dimensions of 362.0 x 351.0 x 388.0mm ( 14-1/4inch x 13-13/16inch x 15-1/4inch ) whereas Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm ( 17-11/16 x 14-3/4 x 21-1/4inch) .
Klipsch SPL-120 is clearly the larger of the two speakers. Its body is 24mm wider, 88mm taller and 152mm deeper than JBL Stage 200P.
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 200P is approximately 1361.9cm2 / 211.1inch2 and base area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2. The Stage 200P requires 33% less surface area than the SPL-120 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 200P weighs 14.45kg / 31.8lbs and the Klipsch SPL-120 weighs 20.45kg / 45lbs. This makes the SPL-120 42% heavier than the Stage 200P.
Here is a comparison of how Stage 200P and SPL-120's weights compare with the average, max and min weights in Powered Subwoofer class.
