Well I have decided to bite the bullet and do it. And I have decided that I want to go with a Cylinder and not a cube, I just like the looks. From their a narrowed it down to either the PC-Ultra or the CS-Ultra with their Samson 1000w amp (500 per channel). My room is 2,600 cu.ft. - it is attached to a 1,700 cu.ft. room buy a 5' wide arch way. This is 95% for watching movies. So I guess the big question is, is their any real difference with a PC and the 525 watt PEQ BASH amp -vrs- the CS with the Samson amp at 500w? With the CS I can see where I can easily add another CS for duals because the Samson will support duals. Also if I only run one CS I can run my bass shackers off the other side of the amp (even though I probably wont need them anymore,LOL) The CS with the Samson is only $150 more then the PS. Also can anyone give me an idea of the out put of say a Ultra or Dual Ultra's -vrs- PB2-Plus. Sorry for all the questions, it got kinda long I guess.
