OK, still talking about the S150s here: I guess In Walls are still a compromise regardless of how good the manufacturer is. If you have not got the size then you cannot get the sound. Do we therefore agree that the S150 in wall versions must be slightly inferior in most aspects than the standard speakers? For example the S150 standard speaker is THX certified whereas it appears the In wall versions are not THX certified. Or is the THX totally irrelvant in this situation?
