Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both ELAC Varro PS350-BKand ELAC Varro PS250-BK have a single woofer setup however the ELAC Varro PS350-BK's woofer is 12-inch whereas the ELAC Varro PS250-BK features a 10-inch woofer.

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 PS350-BK's and ELAC Varro PS250-BK's external dimensions. ELAC Varro PS350-BK has external dimensions of 439.0 x 418.0 x 420.0mm (17-1/4inch x 16-7/16inch x 16-1/2inch) whereas ELAC Varro PS250-BK has external dimensions of 381.0 x 361.0 x 361.0mm (15inch x 14-3/16inch x 14-3/16inch).
ELAC Varro PS350-BK is clearly the larger of the two speakers. Its body is 57mm wider, 58mm taller and 59mm deeper than ELAC Varro PS250-BK.
Below you can see the front view size comparison of ELAC Varro PS350-BK and ELAC Varro PS250-BK in scale.

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 PS350-BK is approximately 1755.6cm2 / 272.1inch2 and base area of the ELAC Varro PS250-BK is approximately 1303.2cm2 / 202.0inch2. The Varro PS350-BK requires 35% more surface area than the Varro PS250-BK 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 PS350-BK weighs 21.86kg / 48.1lbs and the ELAC Varro PS250-BK weighs 16.44kg / 36.2lbs. This makes the Varro PS350-BK 33% heavier than the Varro PS250-BK.

Siblings in ELAC's Varro range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | A | ELAC Varro PS350-BK goes deeper - 24Hz against 27Hz. A real difference, though most music has little content below 27Hz. |
| Amplifier power | A | ELAC Varro PS350-BK has the bigger amplifier - 350W against 250W RMS, about 1.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Varro PS350-BK 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 ported 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). |
| Cabinet size | depends | ELAC Varro PS250-BK is about 36% 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 | ELAC Varro PS250-BK costs less - $649 against $799, about 19% less. |
A ELAC Varro PS350-BK B ELAC Varro PS250-BK
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?
ELAC Varro PS350-BK leads across most of the measured areas for a modest premium, so it is the easier pick if the budget stretches. ELAC Varro PS250-BK is the one to take if it does not. If placement is the constraint - a corner, behind a sofa, under a desk - ELAC Varro PS250-BK is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
