I am planning on getting the Tosh 57HL83 when it comes out this fall. As I understand it, there are no focusing issues as compared to a conventional RPTV. If this is the case, could I safely place a 20-39 PC+ immediately behind the TV knowing that I would not have to worry about any lenses drifting, or would the sub literally shake the TV apart (or damage it in some way)? Both would be placed in the corner of my living room. Thanks for the info.
