Hi. I am a new member from Brazil and i am looking forward to purchase a hi end in-wall speaker system. Doing some research in AV forums, i found the Martin Logan option. However, i need some advice in order to choose the right speakers for my needs. I have a 6,6 X 6,4 multiroom and am planning to have a 7.1 system. Could you suggest me some options for the speakers and the subwoofer? Thanks.
