In this review, we will be comparing RP-1200CSW and SPL-100, two Powered Subwoofer speakers by 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 Klipsch RP-1200CSW and Klipsch SPL-100 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 Klipsch RP-1200CSWand Klipsch SPL-100 have a single woofer setup however the Klipsch RP-1200CSW's woofer is 12-inch whereas the Klipsch SPL-100 features a 10-inch woofer.
Frequency Response
RP-1200CSW has a frequency range of 17-160 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 17Hz, the RP-1200CSW can go significantly deeper on the low side and provide stronger bass compared to the SPL-100's min frequency of 27Hz.
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-1200CSW 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 SPL-100 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 Klipsch RP-1200CSW's and Klipsch SPL-100's external dimensions. Klipsch RP-1200CSW has external dimensions of 399.5 x 376.9 x 416.1mm (15.73inch x 14.84inch x 16.38inch) whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch).
Klipsch RP-1200CSW is 18.5mm shorter and 61.9mm less deeper than Klipsch SPL-100 but it is also 18.9mm wider.
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-1200CSW is approximately 1568.3cm2 / 243.1inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The RP-1200CSW requires 8% less surface area than the SPL-100 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 Klipsch RP-1200CSW weighs 21.64kg / 47.6lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the RP-1200CSW 29% heavier than the SPL-100.
Here is a comparison of how RP-1200CSW and SPL-100'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.
Klipsch SPL-100 needs about 9% more floor area. Klipsch SPL-100 stands 62mm further into the room. Klipsch SPL-100 is 19mm taller.

A sealed subwoofer against a ported one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | A | Klipsch RP-1200CSW goes deeper - 17Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | Klipsch RP-1200CSW has the bigger amplifier - 400W against 200W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1200CSW 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 | depends | Klipsch RP-1200CSW is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch SPL-100 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Price | B | Klipsch SPL-100 costs less - $399 against $850, about 53% less. |
A Klipsch RP-1200CSW B Klipsch SPL-100
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: Klipsch RP-1200CSW measures better, Klipsch SPL-100 costs about 53% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch SPL-100 will hit harder for the money; if it is mainly for music in a normal-sized room, Klipsch RP-1200CSW is usually the easier one to make sound right. 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 $399 each, two Klipsch SPL-100 cost about $798 against $850 for one of the other, which is worth a thought.
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.
