In this review, we will be comparing Foundry F12 and RP-1200SW, two Powered Subwoofer speakers from PS Audio 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 PS Audio Foundry F12 and Klipsch RP-1200SW first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.PS Audio Foundry F12and Klipsch RP-1200SW have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Foundry F12 has a frequency range of 20-500 Hz whereas RP-1200SW has a frequency range of 16.5-138 Hz. With a minimum frequency of 17Hz, the RP-1200SW can go slightly deeper then the Foundry F12's min frequency of 20Hz.
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 PS Audio Foundry F12 has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch RP-1200SW 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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare PS Audio Foundry F12's and Klipsch RP-1200SW's external dimensions. PS Audio Foundry F12 has external dimensions of 425.0 x 375.0 x 444.0mm (16-3/4 x 14-3/4 x 17-1/2inch) whereas Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch).
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 57mm wider, 57mm taller and 215mm deeper than PS Audio Foundry F12.
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 PS Audio Foundry F12 is approximately 1665.0cm2 / 258.1inch2 and base area of the Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2. The Foundry F12 requires 42% less surface area than the RP-1200SW 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 PS Audio Foundry F12 weighs 35.00kg / 77lbs and the Klipsch RP-1200SW weighs 31.18kg / 68.6lbs. This makes the Foundry F12 12% heavier than the RP-1200SW.
Here is a comparison of how Foundry F12 and RP-1200SW's weights compare with the average, max and min weights in Powered Subwoofer class.
