In this review, we will be comparing DS123 and SPL-100, two Powered Subwoofer speakers from ELAC and 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 ELAC DS123 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 ELAC DS123and Klipsch SPL-100 have a single woofer setup however the ELAC DS123's woofer is 12-inch whereas the Klipsch SPL-100 features a 10-inch woofer.
Frequency Response
DS123 has a frequency range of 28-150 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 27Hz, the SPL-100 can go slightly deeper then the DS123's min frequency of 28Hz.
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.

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 ELAC DS123's and Klipsch SPL-100's external dimensions. ELAC DS123 has external dimensions of 374.7 x 360.4 x 446.1mm () 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).
ELAC DS123 is 43.3mm shorter and 31.9mm less deeper than Klipsch SPL-100 but it is also 2.4mm 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 ELAC DS123 is approximately 1607.7cm2 / 249.2inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The DS123 requires 6% 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 ELAC DS123 weighs 13.70kg / 30.1lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the SPL-100 23% heavier than the DS123.
Here is a comparison of how DS123 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.
Near-identical footprints. Klipsch SPL-100 stands 32mm further into the room. Klipsch SPL-100 is 43mm 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 | evenly matched | Effectively the same reach (28Hz vs 27Hz). |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | A | ELAC DS123 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 | ELAC DS123 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. |
| Warranty | B | 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 | B | Klipsch SPL-100 costs less - $399 against $599, about 33% less. |
A ELAC DS123 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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. 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, ELAC DS123 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.
