I kow this is a somewhat similar thread
that member "carp" started but it's for the L/C/R part of your system. Carp, I hope you're not offended
I'm curious to see pics of your frontstage setup when utilising a tower (identical or not) as your center speaker. I'm currently on the lookout for another AS-F1 for my center but would really like to see if you use 2 audio racks (one on each side of the tower), if you relocated your gears away or any other configuration for your audio gears. Or maybe you have a particular suggestion specifically for my setup (post #30 in my sig is the most up to date)
Also, how were the improvements for you? night and day? subtle? none at all?... Did it "widened" your frontstage? Did your off axis response imporve beyond what you expected?
Although my wife don't mind that I use a tower as my center, she has a hard time picturing what it's going to look like.
hope to see lotsa pics
