In this review, we will be comparing RP-1600CSW and RP-1200SW, 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-1600CSW 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.Both Klipsch RP-1600CSWand Klipsch RP-1200SW have a single woofer setup however the Klipsch RP-1600CSW's woofer is 16-inch whereas the Klipsch RP-1200SW features a 12-inch woofer.
Frequency Response
RP-1600CSW has a frequency range of 14.5-175 Hz whereas RP-1200SW has a frequency range of 16.5-138 Hz. With a minimum frequency of 15Hz, the RP-1600CSW can go slightly deeper then the RP-1200SW's min frequency of 17Hz.
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-1600CSW 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 Klipsch RP-1600CSW's and Klipsch RP-1200SW's external dimensions. Klipsch RP-1600CSW has external dimensions of 488.2 x 465.6 x 465.6mm (19.22inch x 18.33inch x 18.33inch) 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 33.6mm narrower and 6.2mm shorter than Klipsch RP-1600CSW but it is also 193.4mm deeper.
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-1600CSW is approximately 2167.8cm2 / 336.0inch2 and base area of the Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2. The RP-1600CSW requires 24% 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 Klipsch RP-1600CSW weighs 35.74kg / 78.6lbs and the Klipsch RP-1200SW weighs 31.18kg / 68.6lbs. This makes the RP-1600CSW 15% heavier than the RP-1200SW.
Here is a comparison of how RP-1600CSW and RP-1200SW'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 RP-1200SW needs about 31% more floor area. Klipsch RP-1200SW stands 193mm further into the room.

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 | evenly matched | Effectively the same reach (15Hz vs 17Hz). |
| Amplifier power | A | Klipsch RP-1600CSW has the bigger amplifier - 800W against 400W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1600CSW moves more air: 16" against 12" is 1.78x the cone area, not the 1.33x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Klipsch RP-1600CSW is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch RP-1200SW 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. |
| Cabinet size | depends | Klipsch RP-1600CSW is about 23% 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. |
| Price | B | Klipsch RP-1200SW costs less - $1,100 against $1,500, about 27% less. |
A Klipsch RP-1600CSW B Klipsch RP-1200SW
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-1600CSW measures better, Klipsch RP-1200SW costs about 27% 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 RP-1200SW will hit harder for the money; if it is mainly for music in a normal-sized room, Klipsch RP-1600CSW is usually the easier one to make sound right.
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.
