Guys - I really don't know what version I have. I am the third owner. I looked, and there is no "aim toward center of room" sticker on either speaker. My system is a 7.1 setup, with the MWTs on the sidewalls, just behind my chair, and a pair of Paradigm Atoms on tall stands near the back wall, some 8 feet behind the listening seat.
IMO, the one thing that makes Ohm Walsh speakers ideal for surround applications, other than the omni-dispersion pattern, is the uniformity of the sonics throughout the line. If you keep up with the columns of Kal Rubinson ("Music In the Round" in Stereophile), and other writers on the subject of surround music (not film soundtracks), having a mismatched surround system, especially in the center, is worse than having no surround at all. Problems arise for people like me who have a combined 2-channel/home theater system, since putting a third tower in the center would match the mains, but block the TV. If my experience with the MWTs and the 2000s is any guide, the Ohm Walsh Center should be a very, very close sonic match for the 2000s, making multichannel music a future possibility for me (although for now, I have no multichannel format player, and use non-matching amps and preamps for the mains and center/surround channels). But I could see how Ohm's approach could solve a lot of problems for those with TVs who want to move to surround sound for music and have uniform sound in each channel. Of course, this use of different size Ohm Walsh speakers requires a subwoofer to handle the deep bass that the smaller Ohms and Ohm center channel speaker obviously cannot reproduce in medium size and larger rooms.
Even though they were close, my Vandersteen VCC-1 center did not match exactly the Vandersteen 1C mains and surrounds I replaced with the Ohms. IMO, few manufacturers even aim for identical sound throughout their product line. Even when they do, the center is usually a compromised design, and a poor sonic match for the tower models in the same line. Ohm is one of the few speaker makers that truly has one "sound" that is just scaled for different room volumes.
