Anyways, after 2 weeks of usage the sub has gotten a little bit more smooth. It's less bloaty especially. It's unreasonable to compare it with my entry level SVS PB-1000 since that's like a whole different league above the RT5.

But otherwise, I think it's decent at best.

I know many people are always skeptical about the whole wireless thing, which is a legitimate concern. I'm always a wired guy, never wireless when it comes to audio. But damn, hats off to Sony. Not a single drop out yet despite me having 14 wireless devices in my home.
I even turn all of them on in the same room to stream a random vid on YT, not a single distortion, cut or clip in the wireless sub and rear speakers of the RT5. 
If you only watch stereo sources, NT3. But at this point, I suggest going for the Philips HTL5140b instead which is even better.

Otherwise, RT5 hands down.
