Hi. I am looking to add to my 7.2 media room to make it 7.2.2. My existing speakers are all Klipsch KHW-5 so I’m thinking that the 6.5” would be a better choice for balance but I’m stuck between the CDT-5650-C II and the CDT-3650-C II, and even whether the 5800 or 3800 would be options to look at as I’m only doing 2 ceiling speakers. I have looked at the specs on paper and see that they are made from different materials, but what is the real difference in terms of sound between the 3000 and 5000 series? Thx! James
