I am in the process of building my EC/HT Center. Before I make a mistake is it OK to place the sw(vtf-2)in the front of the entertainment center? It will be off the ground approx. 30 inches. Also it will be enclosed on 2 sides and back. Don't ask why it can't go on the floor...there are a lot of issues re: that question. However last resort it may have to live there. I have not purchased the SW yet. However the vtf-2 size is right. If in the wall sub would work that may be a possibility. (Will regular speaker wire work with a sw? The back wall is pre-wired, with a outlet .) Thanks in Advance.
