Welcome aboard, Neuumann!
And thanks, Sparge.
Neuumann, don't take Sparge's post personally. It sent up a flare with me too.
We don't allow advertising in forum posts, ad placements are available for that to keep them corralled and support the site, but there have been those who try to game their way around those rules. I deal with them and spammers almost every night.
Anyway, good luck with your Backyard Theater. Looks like you'll have some great gear!
