Derrick824 Posted July 19, 2008 Report Share Posted July 19, 2008 what is the joke?i'm just asking if i am correct Your question itself makes it obvious you already have knowledge of it but then you have to ask "what are the benefits". Sounds like a joke to me. Quote Link to comment Share on other sites More sharing options...
Eskii Posted July 19, 2008 Report Share Posted July 19, 2008 Your question itself makes it obvious you already have knowledge of it but then you have to ask "what are the benefits". Sounds like a joke to me. Ease up tiger. There's no joke. Just some people, like myself, are interested in the more scientific side of sound systems. Coz there's a shitod of stuff! If you wanna stick with tuning freq, amp power, basic stuff, then all good. Don't knock someone for a pretty decent question.

southside connections Posted July 19, 2008 Author Report Share Posted July 19, 2008 hmmm some nice reading there,very informative but i was thinking and if the rear wave is corrected to a full 360degree, then in theory, i should have no cancellation right?

In theory, yes. But any port has an effect on phasing anyway. Besides that the path lengths from the port mouth and the sub to the meter would have to be exactly the same... you're more worried about phasing at the meter than at the box in SPL (obviously) so it's hard to do the maths - it might turn out that you need only 320 degrees of phase or something. This is why I suggested a bandpass arrangement - you can sort out the phasing in a nice controlled enclosure then you only have 1 wave in the car. Quote 10.x volts fo' life!

southside connections Posted July 21, 2008 Author Report Share Posted July 21, 2008 so acordingly,we are trying to get the front and rear wave in perfect alignment at the point of the meter hmmmm this sounds alot easier that is really is,it looks extreemly difficult ok so based on q-wave theory, if the rear wave is properly aligned at the meter together to the front wave,we should be able to score a high spl then?

Perfect coherent phasing will give you +3db Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
