Anyone know what the ZA means? I have been soundbar shopping, I have seen this happen before where a company will add a couple of random letters at the end that is not on their website. In this particular case I am looking at the Samsung HW-R60M/ZA. When you search their site the model is not there. I was able to find a HW-R60M on their support section via google but it did not have the ZA. This was part of a black friday deal I believe so I am assuming these are some lower quality one off model made for black friday and clearance specials? Hard to make a choice here, seems like a great deal and a great soundbar but if it is a low end wal mart special then IDK. Edit: Sorry for the wasted bandwidth. I was able to find this quote with another search. Will leave here in case anyone else comes here searching for the same answer. "ZA: This is the country marker letting us know it's a unit built for use in the USA. You'll see others like HW-K550/ZC in which the ZC means it was built for use in Canada."
