ive installed a few of them, they are roughly equivalent to a decent factory sub. ive installed 3-4 different brands of those type of subs and the RF was the best of the ones ive installed. It is still not close to a dedicated D class monoblock amp with a proper sub in a correctly sized box, but it is better than nothing at a much lower cost.
Personally i would never own one, but i do understand the appeal of it, and if your not trying to get a lot out of it you will likely be happy. I have never had a customer be unhappy with one of them. If you own Martin Logan / B&W / Focal speakers at home or something though you will be disappointed. If you have a shop around that has one on display, it would be good to hear it before you buy it.
