I was reading a recent article that looked at THX Ultra 2 and the way the THX spec has changed. THX EX originally called for dipole surrounds on the side and back positions in a home EX system. Ultra 2 has changed this recommendation to dipoles on the sides and monopoles (direct radiating) at the back surround positions. I have been considering just this thing lately so this article provided all the impetus I needed to dutifully bebop down to my local hi-fi emporium to audition some small monitor-type speakers to use for the back surround channels in my EX system. I found the B&W LM1 indoor/outdoor mini monitors that appeared to fill the bill nicely (I have neither the mounting space nor the budget for either the Nautilus or CDM surround speakers). I've just finished replacing the Atlantic Technology 354SR dipole surrounds I was using on the back channels with the B&Ws and I'm very pleased with the result. So pleased, in fact, that I am now considering replacing the ATs on the side surround channels. The LM1 is not exactly what I would like from a cosmetic standpoint in these positions, but B&W also has a slimline speaker, the VM1, in the same line as the LM1 and is said to be voice matched with the LM1. If anyone has any personal experience with this speaker, please offer any comments on performance, bearing in mind this is to be a surround speaker, not a front channel speaker, and how it looks in an "on wall" placement.
