In this review, we will be comparing Varro RS700-SB 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 RS700-SB 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.Both ELAC Varro RS700-SBand Klipsch R-100SW have a single woofer setup however the ELAC Varro RS700-SB's woofer is 12-inch whereas the Klipsch R-100SW features a 10-inch woofer.
Frequency Response
Varro RS700-SB has a frequency range of 17-150 Hz whereas R-100SW has a frequency range of 32-120 Hz. With a minimum frequency of 17Hz, the Varro RS700-SB 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 RS700-SB has a Acoustic Suspension type cabinet. 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. 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 RS700-SB's and Klipsch R-100SW's external dimensions. ELAC Varro RS700-SB has external dimensions of 439.0 x 418.0 x 420.0mm (17-1/4inch x 16-7/16inch x 16-1/2inch) 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 98mm narrower and 67mm shorter than ELAC Varro RS700-SB but it is also 39mm 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 RS700-SB is approximately 1755.6cm2 / 272.1inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The Varro RS700-SB requires 20% more surface area than the R-100SW 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 ELAC Varro RS700-SB weighs 25.35kg / 55.8lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the Varro RS700-SB 132% heavier than the R-100SW.
Here is a comparison of how Varro RS700-SB and R-100SW's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | A | ELAC Varro RS700-SB goes deeper - 17Hz against 32Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | ELAC Varro RS700-SB has the bigger amplifier - 700W against 150W RMS, about 6.7dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Varro RS700-SB 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 Varro RS700-SB is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch R-100SW 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. |
| Speaker-level inputs | A | ELAC Varro RS700-SB takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Wireless option | depends | Only ELAC Varro RS700-SB 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 R-100SW is about 29% 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 | 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 $1,499, about 82% less. |
A ELAC Varro RS700-SB 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?
The usual trade-off: ELAC Varro RS700-SB measures better, Klipsch R-100SW costs about 82% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch R-100SW will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC Varro RS700-SB is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, ELAC Varro RS700-SB is the only one of these two you can connect at all.
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.
