Is this a bad idea? In my quest to find small bookshelf size speakers, I need to wall mount these. But finding a speaker that meets all of my criteria has been challenging. When I find something I like, there is usually an issue. So I have been looking at the Polk Monitor 30, which are a decent size and weight for wall mounting, but they are rear ported. Will that be an issue? I looked at the Infinity Primus 150 which is dirt cheap, but I think they are too large in size and weight. I also found a pair of NHT - an older model for sale at Onecall the smallest bookshelf, SB1for $79 each in white which would actually be very cool for my application, but they only have 2 left. I would like 3 and use one for center as well. I could also go for the new(er) NHT Absolute Zero Mini that are on sale at J&R Music for $129 each. Then I could get 3 across, which I like, and they are small enough to wall mount I think too, and are not rear ported. I haven't read any reviews of these speakers though. Anyone know anything about them? Are those Polk R30 pretty decent for HT? Reviews seem mostly positive.
