Let me start by saying, that I Love Bass. If the subwoofer does not pound or rattle anything, then I don't want it. I'll admit that I was underwhelmed at first because the sub just wasn't kicking right out of the box. I played it at a low volume to give the speakers a little break-in. Well, they broke in and I cranked it to 26 (it probably goes to 100 but I may blow a window), and WOW!!!!!!!!! This system is a monster. The clarity is crazy. I watched John Wick 3, the scene with Halle Berry and it sounded like they were shooting in my living room. I tried music with a lot of Bass (Future's Album: Mixtape Pluto - Teflon Don) and I wasn't able to turn it pass 25. Now, about MDG. Of course with certain site's you're a little skeptical. Well, MDG is official. They verified my information and the process was seamless. Thanks MDG. I will be ordering again.
