In this review, we will be comparing HTS 12 and R-100SW, two Powered Subwoofer speakers from Polk 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 Polk HTS 12 and Klipsch R-100SW 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.Both Polk HTS 12and Klipsch R-100SW have a single woofer setup however the Polk HTS 12's woofer is 12-inch whereas the Klipsch R-100SW features a 10-inch woofer.
Frequency Response
HTS 12 has a frequency range of 28-120 Hz whereas R-100SW has a frequency range of 32-120 Hz. With a minimum frequency of 28Hz, the HTS 12 can go slightly deeper then the R-100SW'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 Polk HTS 12 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 Klipsch R-100SW have Bass reflex type enclosure.

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 Polk HTS 12's and Klipsch R-100SW's external dimensions. Polk HTS 12 has external dimensions of 478.0 x 437.0 x 510.0mm (18-13/16 x 17-3/16 x 20-1/16inch) whereas Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm (14-5/8 x 12-9/16 x 18-1/16inch).
Polk HTS 12 is clearly the larger of the two speakers. Its body is 117mm wider, 106mm taller and 51mm deeper than Klipsch R-100SW.
Below you can see the front view size comparison of Polk HTS 12 and Klipsch R-100SW 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 Polk HTS 12 is approximately 2228.7cm2 / 345.4inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The HTS 12 requires 52% more surface area than the R-100SW 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 Polk HTS 12 weighs 22.68kg / 49.9lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the HTS 12 108% heavier than the R-100SW.
Here is a comparison of how HTS 12 and R-100SW's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
Polk HTS 12 needs about 52% more floor area. Polk HTS 12 stands 51mm further into the room. Polk HTS 12 is 106mm taller.

Different price classes - Polk HTS 12 costs roughly 2x what Klipsch R-100SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Polk HTS 12 goes deeper - 28Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | Polk HTS 12 has the bigger amplifier - 200W against 150W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Polk HTS 12 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Klipsch R-100SW is about 49% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Warranty | A | Polk HTS 12 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | Klipsch R-100SW costs less - $275 against $549, about 50% less. |
A Polk HTS 12 B Klipsch R-100SW
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Polk HTS 12 measures better, Klipsch R-100SW costs about 50% less. In a normal room, placement will make a bigger difference than the gap between these two. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $275 each, two Klipsch R-100SW cost about $550 against $549 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Klipsch R-100SW is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
