OK, I just had a sales guy at a high end audio store that seemed mad that I ended up buying a Velodyne DLS5000R -vs- the Velodyne DD stuff they carry insult the %#$@#% of me.... I don't even know where to begin with some of the things he said to me... But, I don't think it is crazy or even that unique for that matter to run dual 15" subs in a 20'x30' room..... I am half tempted to call his boss, but he seemed so out of line I found it comedic, I almost enjoyed it even. Well I enjoyed the fact I didn't actually buy a sub from him more than anything else. I have always run my sub pretty darn hot. Maybe I am officially one of those bass freaks now?? I hate to name the store, I have actually had a good relationship with them over the past 10+ years.
