In this review, we will be comparing SPL-100 and Debut 2.0 SUB3030, two Powered Subwoofer speakers from Klipsch and ELAC. 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 ELAC Debut 2.0 SUB3030 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 ELAC Debut 2.0 SUB3030 have a single woofer setup however the Klipsch SPL-100's woofer is 10-inch whereas the ELAC Debut 2.0 SUB3030 features a 12-inch woofer.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas Debut 2.0 SUB3030 has a frequency range of 25-150 Hz. With a minimum frequency of 25Hz, the Debut 2.0 SUB3030 can go slightly deeper then 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 ELAC Debut 2.0 SUB3030 have Passive radiator 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 Klipsch SPL-100's and ELAC Debut 2.0 SUB3030'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 ELAC Debut 2.0 SUB3030 has external dimensions of 462.0 x 451.0 x 464.0mm (18-3/16 x 17-3/4 x 18-1/4inch).
Klipsch SPL-100 is 93mm narrower and 44mm shorter than ELAC Debut 2.0 SUB3030 but it is also 14mm 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 SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the ELAC Debut 2.0 SUB3030 is approximately 2092.6cm2 / 324.4inch2. The SPL-100 requires 18% less surface area than the Debut 2.0 SUB3030 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 SPL-100 weighs 16.82kg / 37lbs and the ELAC Debut 2.0 SUB3030 weighs 22.80kg / 50.2lbs. This makes the Debut 2.0 SUB3030 36% heavier than the SPL-100.

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 | evenly matched | Effectively the same reach (27Hz vs 25Hz). |
| Amplifier power | B | ELAC Debut 2.0 SUB3030 has the bigger amplifier - 500W against 200W RMS, about 4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | ELAC Debut 2.0 SUB3030 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 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; ELAC Debut 2.0 SUB3030 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. |
| Cabinet size | depends | Klipsch SPL-100 is about 26% 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 SPL-100 carries 2 years on parts against 1 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 $900, about 56% less. |
A Klipsch SPL-100 B ELAC Debut 2.0 SUB3030
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?
ELAC Debut 2.0 SUB3030 is ahead, but on only 1 of the measured areas, and it costs about 126% more. Klipsch SPL-100 is the sensible buy unless your room is large enough to need the extra. 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 $900 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.
