So even after several days of research I'm still leaning toward one of the 2 systems that you recommended, however after reviewing the 2 systems I am left with a few questions & would like to get your opinion on them that way in the end I have the best system in my price range, first off, I know how great you say these 15" subs are, and I am sure they are bad ass, in your opinion are these 15 inch subs a make or break deal, I have been checking out the 12" sub from each of the two systems, they look pretty amazing also, i'm just not sure that I need 600 W of power from a 15 inch speaker, but I am asking your opinion as I don't know a lot about this stuff, is going down to the smaller speaker too much of a sacrifice in quality in your opinion, secondly I have my speakers narrowed down to three sets, The first one being five of the HB-1 MK2's and the second option, and this is where I wanted to get your opinion, i've considered upscaling on my front three speakers going with three CMT-340 SE's in the front & two of the CBM-170 SE's in the back, and the third option would just be five of the CBM-170 SE's, considering these three configuration options what in your opinion would give me the best quality of sound, I know this is a lot but I feel like I'm getting better advice from you than anything out there as far as reviews and research goes, thanks once again
