In this review, we will be comparing RP-1200SW and SuperCube 2000, two Powered Subwoofer speakers from Klipsch and Definitive Technology. 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-1200SW and DT SuperCube 2000 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-1200SWand DT SuperCube 2000 have a single woofer setup however the Klipsch RP-1200SW's woofer is 12-inch whereas the DT SuperCube 2000 features a 7.5-inch woofer.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas SuperCube 2000 has a frequency range of 20-200 Hz. With a minimum frequency of 17Hz, the RP-1200SW can go slightly deeper then the SuperCube 2000'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 Klipsch RP-1200SW 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 DT SuperCube 2000 have Passive Radiator type enclosure. 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.
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-1200SW's and DT SuperCube 2000's external dimensions. Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch) whereas DT SuperCube 2000 has external dimensions of 275.0 x 261.0 x 321.0mm (10-13/16 x 10-1/4 x 12-5/8inch).
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 171mm wider, 207mm taller and 338mm deeper than DT SuperCube 2000.

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-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the DT SuperCube 2000 is approximately 837.8cm2 / 129.9inch2. The RP-1200SW requires 240% more surface area than the SuperCube 2000 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 Klipsch RP-1200SW weighs 31.18kg / 68.6lbs and the DT SuperCube 2000 weighs 11.36kg / 25lbs. This makes the RP-1200SW 174% heavier than the SuperCube 2000.

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 240% more floor area. Klipsch RP-1200SW stands 338mm further into the room. Klipsch RP-1200SW is 207mm taller.

A ported subwoofer against a passive radiator 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-1200SW goes deeper - 17Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | DT SuperCube 2000 has the bigger amplifier - 650W against 400W RMS, about 2.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1200SW moves more air: 12" against 7.5" is 2.56x the cone area, not the 1.6x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | 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; DT SuperCube 2000 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Wireless option | depends | Only Klipsch RP-1200SW offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Phase control | A | Klipsch RP-1200SW has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Cabinet size | depends | DT SuperCube 2000 is about 83% 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 | Klipsch RP-1200SW carries 5 years on parts against 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | DT SuperCube 2000 costs less - $599 against $1,100, about 46% less. |
A Klipsch RP-1200SW B DT SuperCube 2000
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-1200SW measures better, DT SuperCube 2000 costs about 46% 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 $599 each, two DT SuperCube 2000 cost about $1,198 against $1,100 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - DT SuperCube 2000 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.
