I researched what kind of speakers I should install in my ABUS whole house audio kit that I recently bought and ended up trying multiple speakers before choosing these. I tried: On-Q ceiling speakers and Dayton speakers and found both of them to be too shallow for my needs. I asked Best Buy if I could get any better deal on these (retail $184.99) and they offered $99.99! I bought 5 pairs on the spot. It took only 10 minutes per set to install and I must say that they sound fantastic! I do have blown in insulation which greatly helps create a box of air for the bass. I would suggested throwing some roll in insulation behind these if you do not currently have it. I will buy more as I expand my system! A+
