Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (19Hz vs 17Hz). |
| Amplifier power | A | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer has the bigger amplifier - 750W against 400W RMS, about 2.7dB 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 12" is 2x the cone area, not the 1.41x 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. |
| Cabinet size | depends | Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer is about 27% 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 | Klipsch RP-1200SW costs less - $1,100 against $2,999, about 63% less. |
A Aperion Bravus III B212S Dual 12" Slim Cinema Powered Subwoofer B Klipsch RP-1200SW
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, Klipsch RP-1200SW costs about 63% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $1,100 each, two Klipsch RP-1200SW cost about $2,200 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.
