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.Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer and B&W ASW608 have a totally different setup: the Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer features 2 x 12-inch drivers whereas the ASW608 features 1 x 8-inch drivers.

A ported subwoofer against a sealed 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 | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer goes deeper - 19Hz 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 | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer has the bigger amplifier - 750W against 200W RMS, about 5.7dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer moves more air: 2 x 12" against 8" is 4.5x the cone area, not the 2.12x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; B&W ASW608 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. 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 | B&W ASW608 is about 75% 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 | B&W ASW608 costs less - $599 against $2,999, about 80% less. |
A Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer B B&W ASW608
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: Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer measures better, B&W ASW608 costs about 80% 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, Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW608 is usually the easier one to make sound right. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $599 each, two B&W ASW608 cost about $1,198 against $2,999 for one of the other, which is worth a thought.
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.
