[QUOTE="Brian Murphy, post: 58273, member: 1805"] Re: Another thread on using different subs When you talk about phase cancellations it reminds me of an experiment I saw a number of years ago. They connected a mic near the tailpipe of a motorcycle and fed it into a preamp with a phase inverter and then to an amp feeding a speaker pointing towards the back of the cycle. Since the souind coming out of the speaker was 180 degrees out of phase with what was coming out of the muffler you could barely hear the cycle run. I suppose if you were off axis it would have been a different story but it was interesting none the less. [/QUOTE]
