Did you wire for speakers in any of the other rooms in the basement/ outside?
This is what I do for a living. I may be able to offer suggestions.
The company I work for, Georgia Home Theater, is in the process of building our new 20k sq ft showroom, it should be done in a month or so. It will be a very nice showroom. We are even putting in a Golf simulator, and will offer those to sell as well. Cobb parkway across from dobbins. We also have a store in Buckhead. Mid to high end audio and video equip/ home automation, alarms, shades, dedicated theaters, housewideaudio and video.
Come see us!
