MickyMcD Posted November 4, 2009 Report Share Posted November 4, 2009 (edited) wow wrong answers, glad ed was hereif u invert, u need to either switch positives and negatives or change phase from 0 to 180 u have to do this once u are ready to fine tune then u can see what sounds best but 90% of the time having the sub in-phase with the rest of the system sounds correct and more accurate inverting will raise box volume and raise tuning u can hook a sub to a wall outlet and it will make sound, does that mean thats what ur suppose to do just because it works, no And what if your system is out of phase by 180 degrees to begin with? What if when you installed your bass driver, it was actually out of phase? And inverting its wiring polarity placed it back in phase? According to you, you MUST invert the phase when inverting driver placement, so in this situation, you just placed your bass driver 180 degrees out from your system phase response. Good job. And further, what if your enclosure had such a terrible group delay that the resulting output was close to inverse phase? And what if the incident wave is being bounced around inside the boot (trunk) badly, and it is almost inverse phase? Tune with your ears, not with the knowledge of how someone else tuned their system. Best RTA you have are located either side of the head.

Decaf Posted November 4, 2009 Report Share Posted November 4, 2009 see the nice thing mick is im fully aware of this and you of all people have an ear for things like this but the average joe wouldnt even be able to tell the difference over the rattles in their cars when it comes to phase example: so if ur doing time alignment... would u just put random distances in or start with actual measured distances for a reference not trying to argue mick, just saying almost everyone who reads this likely wouldnt be able to tell the difference so starting with logical settings is best... then fine tune if u feel it doesnt sound right... which is in the ear of the beholder (btw id love to have ur job ) Quote Link to comment Share on other sites More sharing options...

I disagree with your statement of having to invert phase on driver flip, but I can certainly see and appreciate where you are coming from, and why you made the statement, and how in many cases it is fact.
