I had the pleasure to audition mlong's SVS sub today. mlong is a new member and it was a pleasure to do business with and hang with 'em for a bit. This sub was an absolute monster and the most incredible sounding sub I have ever witnessed. Mark had SDA's front and back with my (his now) CSi30 and THAT SVS. It was just an incredible listening experience. Now I know why the SVS's have the reputation they do. Hope that concrete floor stands up to the abuse. Not to mention the structure integrity of his house. Mark, all ya need now is a kickass amp(s), some DVD-A equipement and a little tweaking. I'm in envy! Just wish I had more time to spend feeling the earth shake.
Just my thoughts.
