Many have smaller bookshelves from their respective line of speakers for surround use, yet in my experiences, I found direct-rads too distracting, even if symmetrically setup 8-10 ft from listening position in a rect room. I have tried a small number of them, starting from Paradigm Titans to their Mini-Monitors to Hales Revelation Ones. I have also owned the Paradigm ADP-100 (dipole) and currently the Mirage OMR2 (bipole). Each time I prefer for HT (I don't do Multi-Ch music) the multi directional speakers because they were immersive and not distracting. I thought it would be interesting to hear from proponents of direct rad surrounds. Perhaps you guys have a diff setup or simply enjoy the diff presentation.
