In this review, we will be comparing Varro PS250-BK and R-100SW, 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 Varro PS250-BK and Klipsch R-100SW 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.ELAC Varro PS250-BKand Klipsch R-100SW have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Varro PS250-BK has a frequency range of 27-150 Hz whereas R-100SW has a frequency range of 32-120 Hz. With a minimum frequency of 27Hz, the Varro PS250-BK can go significantly deeper on the low side and provide stronger bass compared to the R-100SW's min frequency of 32Hz.
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 ELAC Varro PS250-BK 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 Klipsch R-100SW have Bass reflex 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 ELAC Varro PS250-BK's and Klipsch R-100SW's external dimensions. ELAC Varro PS250-BK has external dimensions of 381.0 x 361.0 x 361.0mm (15inch x 14-3/16inch x 14-3/16inch) whereas Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm (14-5/8 x 12-9/16 x 18-1/16inch).
Klipsch R-100SW is 41mm narrower and 9mm shorter than ELAC Varro PS250-BK but it is also 98mm 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 ELAC Varro PS250-BK is approximately 1303.2cm2 / 202.0inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The Varro PS250-BK requires 11% less surface area than the R-100SW 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 Varro PS250-BK weighs 16.44kg / 36.2lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the Varro PS250-BK 51% heavier than the R-100SW.
Here is a comparison of how Varro PS250-BK and R-100SW'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 R-100SW needs about 13% more floor area. Klipsch R-100SW stands 98mm further into the room.

Different price classes - ELAC Varro PS250-BK costs roughly 2.4x what Klipsch R-100SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | ELAC Varro PS250-BK goes deeper - 27Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | ELAC Varro PS250-BK has the bigger amplifier - 250W against 150W RMS, about 2.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Driver placement | depends | ELAC Varro PS250-BK fires down and Klipsch R-100SW fires front. 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. |
| Warranty | B | Klipsch R-100SW 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 R-100SW costs less - $275 against $649, about 58% less. |
A ELAC Varro PS250-BK B Klipsch R-100SW
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 Varro PS250-BK is ahead, but on only 1 of the measured areas, and it costs about 136% more. Klipsch R-100SW 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 $275 each, two Klipsch R-100SW cost about $550 against $649 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.
