In this review, we will be comparing Varro RS500-SB and SuperSub X, two Powered Subwoofer speakers from ELAC and GoldenEar. 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 GoldenEar SuperSub X 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 RS500-SB and GoldenEar SuperSub X have a totally different setup: the ELAC Varro RS500-SB features 1 x 10-inch drivers whereas the SuperSub X features 2 x 8-inch drivers.
Frequency Response
Varro RS500-SB has a frequency range of 18-150 Hz whereas SuperSub X has a frequency range of 12-250 Hz. With a minimum frequency of 12Hz, the SuperSub X can go significantly deeper on the low side and provide stronger bass compared to the Varro RS500-SB's min frequency of 18Hz.
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 RS500-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 GoldenEar SuperSub X have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed 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 GoldenEar SuperSub X'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 GoldenEar SuperSub X has external dimensions of 324.0 x 356.0 x 388.0mm (12-3/4inch x 14inch x 15-1/4inch).
GoldenEar SuperSub X is 5mm narrower and 57mm shorter than ELAC Varro RS500-SB but they have the same thickness of 388.0mm.

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 GoldenEar SuperSub X is approximately 1381.3cm2 / 214.1inch2. The Varro RS500-SB requires 1% more surface area than the SuperSub X 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 GoldenEar SuperSub X weighs 18.18kg / 40lbs. This makes the Varro RS500-SB 15% heavier than the SuperSub X.
Here is a comparison of how Varro RS500-SB and SuperSub X'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.

A sealed subwoofer against a passive radiator 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 | B | GoldenEar SuperSub X goes deeper - 12Hz against 18Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | GoldenEar SuperSub X has the bigger amplifier - 1400W against 500W RMS, about 4.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | GoldenEar SuperSub X moves more air: 2 x 8" against 10" is 1.28x the cone area, not the 1.13x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | ELAC Varro RS500-SB is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; GoldenEar SuperSub X is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. 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 RS500-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 RS500-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. |
| Phase control | A | ELAC Varro RS500-SB has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Driver placement | depends | ELAC Varro RS500-SB fires down and GoldenEar SuperSub X fires side. 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 | GoldenEar SuperSub X carries 3 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 | ELAC Varro RS500-SB costs less - $1,299 against $1,499, about 13% less. |
A ELAC Varro RS500-SB B GoldenEar SuperSub X
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: GoldenEar SuperSub X measures better, ELAC Varro RS500-SB costs about 13% 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, GoldenEar SuperSub X will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC Varro RS500-SB is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, ELAC Varro RS500-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.
