This is my home theater that I put together piece by piece over a couple years. I use all Psb speaker with 4 Sunfire HRS-12 subwoofers. It's just a 7.4 system meaning 7 channels and 4 subwoofers. After extensive room correction it sound wonderful. I plan to add Atmos speakers very soon. I've already purchased some Psb Atmos speakers I just haven't  found the time to install them. Until then me and my family will enjoy movies just the way it is!
