In this review, we will be comparing SPL-100 and Muro SUB2020, 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 Muro SUB2020 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.Klipsch SPL-100and ELAC Muro SUB2020 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas Muro SUB2020 has a frequency range of 28-200 Hz. With a minimum frequency of 27Hz, the SPL-100 can go slightly deeper then the Muro SUB2020'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.

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 Muro SUB2020 have Acoustic Suspension type enclosure. 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.
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 Muro SUB2020'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 Muro SUB2020 has external dimensions of 399.0 x 185.0 x 515.0mm (15-11/16 x 7-1/4 x 20-1/4inch).
ELAC Muro SUB2020 is 173mm narrower and 19mm shorter than Klipsch SPL-100 but it is also 37mm 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 Muro SUB2020 is approximately 952.8cm2 / 147.7inch2. The SPL-100 requires 80% more surface area than the Muro SUB2020 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 ELAC Muro SUB2020 weighs 12.73kg / 28lbs. This makes the SPL-100 32% heavier than the Muro SUB2020.
Here is a comparison of how SPL-100 and Muro SUB2020'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 80% more floor area. ELAC Muro SUB2020 stands 37mm further into the room. Klipsch SPL-100 is 19mm taller.

A ported subwoofer against a sealed 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 28Hz). |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| 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 Muro SUB2020 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Driver placement | depends | Klipsch SPL-100 fires front and ELAC Muro SUB2020 fires side or down. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | ELAC Muro SUB2020 is about 47% 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 $1,000, about 60% less. |

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?
Klipsch SPL-100 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. 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 Muro SUB2020 is usually the easier one to make sound right. 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 $1,000 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.
