Hello fellow DIYers...
I have a pair of Q1r HiVi tweeters and someone is willing to make me Cross over including Baffle Step Correction.
But that requires some T/S parameters Qes, Qts and Qms.
So i have google'd for quite a while and used the 'search' function on this forum, sadly without any results of the T/S parameters.
I also checked Zaph his site but it isnt listed there with the parameters.
Can anyone help me out here, so i can finish the simulation?
Much appriciated
Marcel

Re:'that requires some T/S parameters Qes, Qts and Qms" - you don't need these for a tweeter, only the impedance plot is required for crossover calculations

A simulation would make much more sense when done after
yourown measurements.
What is the woofer's make and model?

I can't recommend building a speaker based only on manufacturer's
plots, so this serves only as an exercise. Acoustic offset is guessed
to be 20 mm, and the driver phase is far from being optimal. The red
dot is mic's position. Baffle step is acounted for as the drawing suggests
with 0,25" rounded edges. Driver slopes are true acoustic LR4, in this
theoretical case, 10 litres box.

Thnx a lot, may i ask you what program you have used?
At first i wanted the make the cabinet really narrow, nearly as wide as the woofer its self, due the reflections.
But i was reading on the page of Troels Graven and i noticed the bit that the edges need to be round, so i went from 15 to 18cm and 30/32cm tall.
The faceplate of the tweeter is 12 cm so thats quite big and will get me in trouble with the lay out if i dont go around 30/32 cm of height
And may i ask why you did used a series filter?
Im kinda new in the XO world and i want to know how it works so i dont have to bother other people anymore with my nonsense 😛
I always thought a parallel filter was easier and more precise due the fact you split up the signals... once again im new in to this and this is just my own theoritical brain fart.
thanks again for your effort.

The filter is a straight parallel type, it's plotted differently than usual.
Read through older threads and you'll find all the information you need.
