Hi All, Just recently I bought a new house and am now in the process of planning. I'm considering installing 4 ceiling speakers as Atmos addition to my 5.1 Reference Premiere setup. Now that I'm doing some preparation and reading I found a lot of websites stating that a backbox should be used for/with ceiling speakers. However, unfortunately I can hardly find any information if this also counts for products from klipsch, particularly for for example the 160rpc which I currently have shortlisted as the addition. Is there someone who may be able to answer the question; is it recommended (also) for the 160rpc to use a backbox with it? I tried searching the forum but couldn't really find a straightforward answer. I hope someone may be able to help me. https://www.klipsch.com/products/pro-160rpc-in-ceiling-speaker https://www.klipsch.com/architectural-accessories
