AH! I totally read that post as a raised eyebrow to my current handy work and speaker choice. Words like "fartbox" were getting thrown around and it was starting to get weird ;-) I was poking fun back.
I am a game designer who is doing this as a fun project that the family can enjoy. And I know I am not going to build the best setup. It has been super fun and educational so far. The room shape and size cant be changed and will always be a limiting factor. The sub I have does make the system sound and feel better; to the tune of about $200. I assumed, due to the room shape and size, that an investment in a better sub would be me throwing money at a $1000+ sub only to have the room kill its performance.
I will take a look at the DIY article. I am capable but my wife may kill that particular project when she hears what I intend to do ;-)
Thank you again!
