I am trying to help a friend find two pair of in-wall speakers for his new house & HT system. They can be any size because they are being custom installed however he can only spend $700 for both pair. He will have 18ft cathedrsl ceilings and the room will be 18ft x 15ft. He will use an existing VMPS center channel and sub. ANy help will be greatly appreciated. Does Madisound still offer in-wall's? I did not see them on their website.
