Thank you for your responses JP. Pardon my ignorance, but what do you mean by a top portion? Build an OB sub into the bottom of the N3?
Due to real estate concerns I was thinking about building the subs into the entertainment center, but under the speakers would take care of that also. The N3S would be a perfect candidate to build in.
I love the concept of the A/V-1RS for the surrounds, considering what the surrounds actually do would they be a decent fit for the N3, N3S combo?
