Unfortunately, that is true about the disperson. The tweeter 'horn' looks like it is not square, so it cannot be rotated. Too bad. If I was willing to give up the space to have a pair of the RC-62 IIs on their sides I would jump to a pair of La Scalas. Perhaps I can convince (LOL) Klipsch to put the tweeter from the RF-7 II into the RB-82 II box. Thanks.
