Hello all, Looking for a little advice. Moved into a new home and previous owner left a bose Acoustimass 10 IV in the family room. Room is about 20 by 15 so not very big. I have been using them for a while and they are as we all know, not the best. I have a 5.1 setup of some older Mirage AVS-200's/100 and a Mirage FRX-s8 sub. Any opinions on if I can get the bose to sound better then the Mirage's. All of them are older speakers, but no budget to upgrade at this point. I have a new Denon-s930h receiver since my old onkyo just kicked the can after 10 years. Thanks
