Seeking advice on height speakers and/or wall mounting R-51Ms. in Home Theater Posted September 6, 2021 @hobbyinn Thanks so much for the heads up about the rear port - my other speakers aren't rear ported so it hadn't occurred to me and I almost did the opposite. I have a set of wall mounts which is really a little multiple position shelf you put the speaker on but I didn't want to use them because the speakers weren't close enough to the wall. Considering your tip about the ports, I guess I should rethink and remeasure. Thanks again.
