In this review, we will be comparing Varro RS500-SB and SB-1000 Pro, two Powered Subwoofer speakers from ELAC and SVS. 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 RS500-SB and SVS SB-1000 Pro 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 RS500-SBand SVS SB-1000 Pro have a single woofer setup however the ELAC Varro RS500-SB's woofer is 10-inch whereas the SVS SB-1000 Pro features a 12-inch woofer.
Frequency Response
Varro RS500-SB has a frequency range of 18-150 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 18Hz, the Varro RS500-SB can go slightly deeper then the SB-1000 Pro's min frequency of 20Hz.
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
Both ELAC Varro RS500-SB and SVS SB-1000 Pro have Acoustic Suspension type cabinets. 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 ELAC Varro RS500-SB's and SVS SB-1000 Pro's external dimensions. ELAC Varro RS500-SB has external dimensions of 381.0 x 361.0 x 388.0mm (15inch x 14-3/16inch x 15-1/4inch) whereas SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch).
SVS SB-1000 Pro is 30mm narrower and 38mm shorter than ELAC Varro RS500-SB 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 ELAC Varro RS500-SB is approximately 1400.7cm2 / 217.1inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Varro RS500-SB requires 5% more surface area than the SB-1000 Pro 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 RS500-SB weighs 20.85kg / 45.9lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the Varro RS500-SB 76% heavier than the SB-1000 Pro.
Here is a comparison of how Varro RS500-SB and SB-1000 Pro'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. ELAC Varro RS500-SB is 38mm taller.

Different price classes - ELAC Varro RS500-SB costs roughly 2.2x what SVS SB-1000 Pro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (18Hz vs 20Hz). |
| Amplifier power | A | ELAC Varro RS500-SB has the bigger amplifier - 500W against 325W RMS, about 1.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS SB-1000 Pro 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction, onboard DSP and app control). |
| Driver placement | depends | ELAC Varro RS500-SB fires down and SVS SB-1000 Pro 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 | SVS SB-1000 Pro carries 5 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 | SVS SB-1000 Pro costs less - $600 against $1,299, about 54% less. |
A ELAC Varro RS500-SB B SVS SB-1000 Pro
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?
SVS SB-1000 Pro has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. 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 $600 each, two SVS SB-1000 Pro cost about $1,200 against $1,299 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.
