I'm assembling a 7.1 HT setup and considering the TCi series - 3 rectangular in-wall for the front and 4 circular in-ceiling for side and rear. The TCi series are within budget - TC65i for the front. When looking for "matching" side and rear there is the TC60i and TC80i with 6.5" and 8" mid-range driver respectively.
How do I choose between the 6.5" and 8"? Simply listen to them?
