I am new to this forum. I have ONKYO a/v receiver and 5.1 BOSE speakers and having it for more than two years. Its being good syetem watching movies with small rooms. Now i am planning to upgrade only front speakers and planning to move my bose speakers to surround as my a/v receiver support 7.1 channel output. I am expecting the real Deep bass effect so of course my Sub woofer also need to be changed. Can any one recommend me front speakers and sub woofer?.
