Thanks for the input drseid,I probably listen to HT and music about the same amount of time,I love both,so a sub that will do all would be my pick.We will only be in our house for another 5 years then it's off to a much bigger home,so the Titan might be a keeper.The Infinity isn't the end all of subs,but set right it does it's job.Both are overkill for my space I think,I'm not sure I even need an external sub with the powered dual tens in each of my RSF1000's,thats four powered tens up front and they aren't shabby,they get tight and they go low,so I might be adding the overkill myself,my wife says I can return the Infinity for some rear surrounds,so I'm not going to step on any toes.
