Matching Tweeter to Woofer & Xover

Higo · 12th March 2002, 05:59 PM

Hello guys. I have a woofer with SPL of 90 (8 Ohms) and 98 (4 ohms). I designed a L-pad with R serial 4.7 Ohms and R parallel of 8 Ohms. I´ll attached the tweeter´s impedance measurements that I did. Is It all right???
I designed the Xover too. I decided to Xover in 2K5, ´cause the
frequency response of the woofer It´s not linear above this range.
Butterwoth or Bessel???
I believe Bessel. With Q=0.5, I have C=4.7uf and L=900uHy
Butterworth...Ummm. With Q=0.707, I have C=6.8uf and L=600uHy.
Any comments??? If I made something wrong, please let me now.
Thanks in advance.
Marcelo.

I also need help matching woofer and tweeter. both are scan speak and i am trying to build some loudpeakers for studio monitoring and mixing use.

I am therefore trying to achieve maximally flat frequency response. do these two match well? any help from anyone would be muchly appreciated. cheers
