In this review, we will be comparing DS123 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 DS123 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.ELAC DS123and SVS SB-1000 Pro have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
DS123 has a frequency range of 28-150 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 20Hz, the SB-1000 Pro can go significantly deeper on the low side and provide stronger bass compared to the DS123's min frequency of 28Hz.
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.

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 DS123's and SVS SB-1000 Pro's external dimensions. ELAC DS123 has external dimensions of 374.7 x 360.4 x 446.1mm () 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).
ELAC DS123 is clearly the larger of the two speakers. Its body is 29.4mm wider, 31.7mm taller and 44.1mm deeper than SVS SB-1000 Pro.
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 DS123 is approximately 1607.7cm2 / 249.2inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The DS123 requires 21% 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 DS123 weighs 13.70kg / 30.1lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the DS123 16% heavier than the SB-1000 Pro.
Here is a comparison of how DS123 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.
ELAC DS123 needs about 21% more floor area. ELAC DS123 stands 44mm further into the room. ELAC DS123 is 32mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | SVS SB-1000 Pro goes deeper - 20Hz against 28Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS SB-1000 Pro has the bigger amplifier - 325W against 200W RMS, about 2.1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | SVS SB-1000 Pro is about 24% 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 | 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 | evenly matched | Priced within a few per cent of each other. |
A ELAC DS123 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.
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.
