In this review, we will be comparing SPL-100 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 SPL-100 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 SPL-100and DT SuperCube 2000 have a single woofer setup however the Klipsch SPL-100's woofer is 10-inch whereas the DT SuperCube 2000 features a 7.5-inch woofer.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas SuperCube 2000 has a frequency range of 20-200 Hz. With a minimum frequency of 20Hz, the SuperCube 2000 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 SPL-100 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 SPL-100's and DT SuperCube 2000's external dimensions. 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) 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 SPL-100 is clearly the larger of the two speakers. Its body is 97mm wider, 143mm taller and 157mm 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 SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the DT SuperCube 2000 is approximately 837.8cm2 / 129.9inch2. The SPL-100 requires 104% 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 SPL-100 weighs 16.82kg / 37lbs and the DT SuperCube 2000 weighs 11.36kg / 25lbs. This makes the SPL-100 48% heavier than the SuperCube 2000.
Here is a comparison of how SPL-100 and SuperCube 2000'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 104% more floor area. Klipsch SPL-100 stands 157mm further into the room. Klipsch SPL-100 is 143mm 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 | B | DT SuperCube 2000 goes deeper - 20Hz against 27Hz. 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 200W RMS, about 5.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch SPL-100 moves more air: 10" against 7.5" 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 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; 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 SPL-100 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 SPL-100 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 68% 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 | B | DT SuperCube 2000 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 | A | Klipsch SPL-100 costs less - $399 against $599, about 33% less. |
A Klipsch SPL-100 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?
DT SuperCube 2000 is ahead, but on only 1 of the measured areas, and it costs about 50% more. Klipsch SPL-100 is the sensible buy unless your room is large enough to need the extra. 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.
