No regrets

Rocking a nice set of Snells and this is exactly what was missing. I will be getting another because I like lots of bass and this thing is amazing. Should have done it sooner.

Need One More!

Connected One 12S to a pair of Swan OS-10 powered desktop speakers with 31 watts RMS per channel maybe. Stupid Fun I guess? But the 12S works even with small speakers. I Do have a Outlaw Receiver and some Schiit Audio EQ and Elac Towers. You still need a second sub even with the level I have. Best Bag For The Buck Subwoofer Period.

Night and Day Difference; if you've got the room, go big

I was on the hook for a 10S MKII; and last minute elected to jump up to the 12S. I have not one single time since them thought about the 10S. This 12S delivers amazing depth and punch to movies; TV shows; and music that I couldnt even image. I'm using it in a rather large open-concept living room that is easily 800 sq ft or larger; and it delivers amazing depth and bass in the entire space. I'm blown away at how much of a difference this made in my home theater. Yeah; its a bit large, but again, I've not thought about that one single time since buying. Even my wife didnt bring it up after the first time we used it. I'd gladly trade off the footprint for the impact this subwoofer has had.

If you're on the fence; just buy it. I LOVE mine.

Meticulously crafted for excellence
