Re: Room EQ Wizard Doubles as Crossover Design/Measurement Tool


whilst this procedure can't give absolute values to the measurements (unless s/one with the suitable mathematical skills can work out a correct formula-is that possible?)I'm also guessing that it may help us determine the correct amount of stuffing in a sealed box for example?

IIRC the resonance (and therefore the impedance) of the system drops with stuffing and will cease falling and start rising when the correct amount has been added. I would have to hunt around to get the exact data, but I think that's right??

If that is kinda correct then it might take the guesswork out of how much stuffing to put in. Maybe it would help with the vented boxes and LLT's too, one for Steve Callas perhaps, tho he's probably way ahead of such crude techniques.

Am I on the right track here?? cause I'm soon to start building my subs and so it would be a timely discovery.
