makes since. Is it 8+ sub or 9+ sub?

a. Answer: .9 Speakers plus 1 subwoofer for a total of 10.

RFI 77

1. The specification is calling for 72" door and panel height. The description sounds like our Hiny Hider system.

On the drawing is a detail for what might look like our ARIA system. Our ARIA system can have a 1"

clearance for the 79" door with 0" standard for the panels. It has a headrail just beneath the ceiling and is

available in heights from 86" to 110" . Can you please clarify product type? I have attached an ARIA form if

ARIA is required.
