(not you ed) Look at anything off a 240v signal..they have no + or -. It is a/c. hence it has no + and -, - A/C stands for "alternating current" i.e it flows back and forth through both terminals. - D/c flows in through one terminal and out the other...just like a speaker works. Having a speaker in a boot firing in any direction has no relevance to its polarity or setup. you can wire up any speaker in any way to suit how you like the sound. Wiring a speaker out of phase doesnt damage the speaker in any way either. A speakers maximum excursion characteristics, are the max it can go forward without slapping the voice coil, and the maximum it can move backwards without smashing the voice coil on the magnet. E.g i have a 15" 2000w speaker. Its max excursion is around 2" or 50mm. This means, the speaker moves 1" out, and 1" in. overall movement being 2". All wiring the speaker out of phase does is time delay. I.e wiring it out of phase will give a delay on the speaker wired so. A lot of good quality speakers in boxes, with 2 way horns/ speakers. have the hf driver wired out of phase, because coupled to its horn flare, its magnet sits a lot further back then the speakers'. Hence you need to put a delay on the horn to make the sound co-herent...wire it out of phase is the answer. [Updated on: Mon, 08 March 2004 11:53] [Report message to a moderator]
