In this review, we will be comparing Varro DS1000-BG and A120P, two Powered Subwoofer speakers from ELAC and JBL. 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 DS1000-BG and JBL Stage A120P 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 DS1000-BG and JBL Stage A120P have a totally different setup: the ELAC Varro DS1000-BG features 2 x 10-inch drivers whereas the A120P features 1 x 12-inch drivers.
Frequency Response
Varro DS1000-BG has a frequency range of 18-150 Hz whereas A120P has a frequency range of 32-150 Hz. With a minimum frequency of 18Hz, the Varro DS1000-BG can go significantly deeper on the low side and provide stronger bass compared to the A120P'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 DS1000-BG 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 JBL Stage A120P 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 DS1000-BG's and JBL Stage A120P's external dimensions. ELAC Varro DS1000-BG has external dimensions of 372.0 x 431.0 x 372.0mm (14-5/8inch x 16-15/16inch x 14-5/8inch) whereas JBL Stage A120P has external dimensions of 415.0 x 393.0 x 475.0mm (16-5/16 x 15-7/16 x 18-11/16inch).
ELAC Varro DS1000-BG is 43mm shorter and 103mm less deeper than JBL Stage A120P but it is also 38mm wider.

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 DS1000-BG is approximately 1603.3cm2 / 248.5inch2 and base area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2. The Varro DS1000-BG requires 14% less surface area than the A120P 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 DS1000-BG weighs 32.45kg / 71.4lbs and the JBL Stage A120P weighs 18.68kg / 41.1lbs. This makes the Varro DS1000-BG 74% heavier than the A120P.

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 DS1000-BG goes deeper - 18Hz 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 DS1000-BG has the bigger amplifier - 1000W against 250W RMS, about 6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Varro DS1000-BG moves more air: 2 x 10" against 12" is 1.39x the cone area, not the 1.18x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | ELAC Varro DS1000-BG is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; JBL Stage A120P 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 DS1000-BG 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 DS1000-BG 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. |
| Driver placement | depends | ELAC Varro DS1000-BG fires side and JBL Stage A120P 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. |
| Cabinet size | depends | ELAC Varro DS1000-BG is about 23% 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. |
| Price | B | JBL Stage A120P costs less - $300 against $2,499, about 88% less. |
A ELAC Varro DS1000-BG B JBL Stage A120P
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 DS1000-BG measures better, JBL Stage A120P costs about 88% 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, JBL Stage A120P will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC Varro DS1000-BG is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, ELAC Varro DS1000-BG 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.
