Thanks very much! This is exactly what drove me to this business venture. Not only could I not find anything that centralized the sub, I couldn't find any products in this area that would accomodate the larger center channels we're starting to see in the market. I will definitely be updated my progress on this forum and, of course, I'd love to get to the point of shipping nation wide.
The idea is to be completely custom built for your specific components... so we'll see what happens!
On the topic of low end response in a centralized, surrounded setting like this; I only feel comfortable with this setup when the sub is of the front-firing, front-ported design. Not saying it can't happen with a front firing sub but I do know if you stuck a down-firing, rear ported sub in that location, you would cause some very funky problems with standing waves and who knows what else!
