I'm sure you are aware that the RC-Mini is a very small speaker, much smaller than the RTi6 or P152. For reference, the palm of your hand will probably completely cover the face of the cabinet. Having said that, it seems to be a high quality speaker for it's size. I've heard them and I like the way they sound within their limitations. As long as the room isn't huge and you aren't asking for crazy loud volume, they can make a nice sounding yet discrete audio system when combined with the Hsu sub.
