Hi ladies and gents,
I’m currently busy designing my own crossover for fun.
I’m using the Dayton DS135-8 (paper cone) woofer and the Dayton ND28F-6 tweeter.
I wanted to go about this scientifically, so I’m using an umik to measure and then make the crossover in xsim.
First question is, how do you measure 1W@1M for either speaker, since one is a 8 ohm speaker and the other a 6 ohm speaker?
Right now I did the following:
– Measured 2,83V output from the amp outputting a @60Hz sine using a DMM, then on the same volume setting measured the DS-135-8
– Measured 2,3 V output from the amp outputting a @60Hz sine using a DMM, then on the same volume setting measured the ND28F-6
Furthermore, in order to ensure the sound sources are aligned (i.e. woofer is about .4 inches recessed) in the crossover I want to take a measurement in parallel, which should be easy to do. However, seeing that both drivers have different impedances, do I measure them both at 2,83V? You can probably see the source of my conflict, this method conflicts with above method of measuring at 1W@1m, meaning that the tweeter levels will be different.
Can this still work? What would you recommend I do to measure the drivers in order to input in xsim?
