IMHO, the super BAM really changes the character of the speaker. If you're going to place them out more than app 3 1/2' from the nearest wall, I'd say it's a must. If you're gonna put 'em closer to the walls, the SEs might be a practical option. IME, near wall placement causes imaging to suffer a bit, but Bobby has posted that he's had success with this placement by thoroughly damping the wall - something I couldn't do.
Either way, it's a great speaker.
