... or anywhere else for that matter. Sometimes I just don't understand what possesses people to do the things they do. That's the case with my good friend Doug. Doug knows more about sound and mixing than anyone I know or have met. He used to have a sound company but he sold all his stuff because he became frustrated that people were unwillingly to pay for quality and, basically, expected him to work for free. As musicians, I am sure we all feel his pain. Anyway, one of his earliest PAs was one he designed and built himself. He ended up parting it out and buying a bigger, name-brand one because promoters have an aversion to custom-built speakers. The subs he designed were awesome. He still has one of them - it's mate is in an installed system. This cabinet has two 18-inch JBLs woofers in it and it was designed to have an F3 of 30Hz which has been verified with RTA equipment. Each cabinet is about like a full-sized refigerator so they were not fun to haul around. It is truly spectacular to hear four of those cabinets thundering away and it is a rare thing to hear frequencies that low reproduced so loud and clean. Anyway, here is the weird part. I went over to visit Doug the other day and he did something I never, ever would have even considered doing. Apparently, he became bored for a while and with this guy that can be a dangerous thing. He told me that he had popped the jack panel off of his sole remaining subwoofer cabinet and rewired the speakers to be in series. Since they are each 8Ω that means the cabinet was a 16Ω load. What I hadn't noticed was he had taken an old AC cord and put a Speak-On connector on one end of it. He looked over and told me, "brace yourself and listen to this, ..." With that, he plugged the AC cord straight into the wall. That's right, a cabinet with two 18-inch JBLs was plugged straight into the wall and fed 60Hz at 120V. I have only ever been around something like that once (I won't bother you with that story) and it was an unbelievable thing. The sound from the cabinet was so damned loud I could feel it all over - it was overwhelming. If you do a bit of math with Ohm's law you will find that this meant 7.5A and 900W were being drawn by the cabinet which was no strain for those woofers. He told me he had verified this before he did anything to make sure it was safe. For the speakers, that is. For the building - not so much. As kids, we used to amuse ourselves with capacitor "bombs" and stuff like that but, damn, plugging a speaker into the wall? Who thinks of things like that? Remember folks, don't try this at home! Serious damage is entirely likely and bodily injury is possible.
