[QUOTE="kouger, post: 8855623, member: 689597"] I did come across another forum where they were changing out the speakers and one of the posts mentioned the reverse polarity. Now this is beyond me and I am not understanding it all - just want to make sure I connect the speakers up correctly. Should I connect the speakers in reverse per the post below or connect them correctly according to what I tested? Here is the comment from the other forum: With very, very few exceptions (like a manufacturing error) a + voltage applied to the + speaker terminal results in forward/outward movement of the cone. It easy to see on a woof or mid, but you may have to use your finger to feel the movement on a tweet. In any case, in [B]system [/B]design, especially for even order (2nd, 4th...) passive crossovers, the crossover electrical terminals will be flipped in polarity on [U]one [/U]driver; + crossover output to - terminal on tweet, for example. This is done to prevent a rather deep response hole in the [U]combined acoustic response[/U], where the woof and tweet interact (cancel each other) acoustically at crossover. Flipping the tweet to + polarity connection for a even order crossover (popular topologies) will create a hole that some people might initially find pleasant, but may later realize it just ***** out that portion of the music. For electronic crossovers, the polarity flip typically happens in the electronics, where all the drivers are electrically connected + to +. [/QUOTE]
