I have 2x R12SW for more than 5 years now and they still kickig out clean and deep bass. 0 issues. I even eq'd them so they play lower than their advertised spec. In my listening spot they hit as low as 27hz, but when i move to another spot in the house they hit 24hz easily, even 20hz very audible and shakes the entire appartment. I almost pee'd my pants when i was testing 20hz, because the TV or it's wall mount started to rattle at some point. Image suddenly hearing a loud metallic rattle sound from your TV😂😂 Just be carefull not to overdrive them or anything. But even that seems impossible to do because they (and like almost any active subs) have built in limiters and protection. For me, they are a great value!
"I don't know how to limit the volume to levels that my amp is capable of dishing out, and blew out the amp. The sub is trash because i'm incapable of using restraint."
