this friday i brought out all 4 cabs ( i just got a great deal on a used bag end S12), for a test drive. the room is notoriously quiet (i.e. you can turn up pretty loud and 20 feet away you can have a conversation at normal levels.) so i figured it would be a good place to try it. besides i thought it would be funny to see the reaction of the woman who always asks us to keep it down when she saw my stack. the contestants were all bag end; a D10B on it's side, an S15, and two S12's, all in the deep red flavor. Total height was a bit over six feet when adding the addtional height from the stack lock corners. With the two 2 space skb racks and my electric blue head (used as a 2nd preamp) an top, i think i was pushing over 7 feet tall. do a search and you'll find why vertical arays are superior to horozontal placement. all i'll tell ya here is it sounded as good as i ever have. (i even got a bunch of "tone" compliments - ). of course i never got past about 3 on the volume. on saturday i had all that with me for a much smaller gig, and as i was so wiped out i never unpacked the car from the night before. i had to bring it all in as we were in a sketchy area. much different band, plays quieter, smaller room, had the amp on about 1. that night i just made two side by side stacks. guess what? it sounded ok, but nowere near as clear and articulate as the vertical stack. i know a pic exits so i'll post it for a laugh when i get a copy.
