In the process of upgrading my gf's(this is where in-wall comes into play) AV set up. There is limited space, so I am going to mount the TV above the mantle. The speakers will be under the TV. Leaning towards going with just a 2 speaker/LR system, although I could possibly go LCR. Not going to use any side or rear speakers. I have a HSU STF2 to go with it. I would like to keep things around $500-$600 if possible. Looked at some of the Def Tech speakers, but I have no experience with in-wall speakers. I saw some HSU in-wall speakers on their website, but not many reviews online. Anyone have any suggestions?
