In this review, we will be comparing Debut S10 2 and ProSub 800, two Powered Subwoofer speakers from ELAC and Definitive Technology. 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 Debut S10 2 and Definitive ProSub 800 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 Debut S10 2and Definitive ProSub 800 have a single woofer setup however the ELAC Debut S10 2's woofer is 10-inch whereas the Definitive ProSub 800 features a 8-inch woofer.
Frequency Response
Debut S10 2 has a frequency range of 35-150 Hz whereas ProSub 800 has a frequency range of 20-150 Hz. With a minimum frequency of 20Hz, the ProSub 800 can go significantly deeper on the low side and provide stronger bass compared to the Debut S10 2's min frequency of 35Hz.
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 Debut S10 2's and Definitive ProSub 800's external dimensions. ELAC Debut S10 2 has external dimensions of 368.3 x 344.5 x 379.4mm () whereas Definitive ProSub 800 has external dimensions of 328.0 x 262.0 x 423.0mm (12-7/8 x 10-5/16 x 16-5/8inch).
Definitive ProSub 800 is 82.5mm narrower and 40.3mm shorter than ELAC Debut S10 2 but it is also 43.6mm 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 Debut S10 2 is approximately 1307.0cm2 / 202.6inch2 and base area of the Definitive ProSub 800 is approximately 1108.3cm2 / 171.8inch2. The Debut S10 2 requires 18% more surface area than the ProSub 800 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 Debut S10 2 weighs 13.02kg / 28.6lbs and the Definitive ProSub 800 weighs 11.82kg / 26lbs. This makes the Debut S10 2 10% heavier than the ProSub 800.
Here is a comparison of how Debut S10 2 and ProSub 800'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 Debut S10 2 needs about 18% more floor area. Definitive ProSub 800 stands 44mm further into the room. ELAC Debut S10 2 is 40mm taller.

A ported 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 | Definitive ProSub 800 goes deeper - 20Hz against 35Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | Definitive ProSub 800 has the bigger amplifier - 300W against 100W RMS, about 4.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Debut S10 2 moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | ELAC Debut S10 2 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; Definitive ProSub 800 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. |
| Cabinet size | depends | Definitive ProSub 800 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. |
| Price | evenly matched | Priced within a few per cent of each other. |
A ELAC Debut S10 2 B Definitive ProSub 800
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?
Definitive ProSub 800 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.
