Let me start off by saying I am no audiofile by any means, and this is actually my VERY first attempt at a surround sound setup.
I ordered 4 monoprice 8" in wall speakers for my living room and I must say, I am extremely satisfied with the results. I'm using them as the Front left and right, as well as the rear left and right. I'm using a polk Audio as my center channel, and just added a DIY sub using a SD12 from creativesound.ca and the Bash 300 amp. They sounded good before the subwoofer addition, but since adding it, the listening pleasure has greatly increased. My receiver is a Denon 1508. I am positive that there are much better speakers to be had, but in my opinion, you will not find a better sounding speaker for the price of these. I don't have any pictures, but I ended up not painting them just because I was to anxious to get them installed. I know, I'm impatient, but they look fine in my opinion. Installation was a breeze.
I haven't decided if I'll use these speakers when I start working on my dedicated HT yet. I may go with some higher end components for that, but it will depend on my financial situation at that time. If the bank account doesn't allow for upgrades, I'll have no problem at all using these again for the dedicated HT.
Again, keep in mind that this is my first 5.1 setup, and I have nothing to really compare it to, other than my previous experience with car audio, which is a totally different monster.
