Please check my 3 way 12dB crossover design

Cal Weldon · 10th December 2004, 12:58 AM

It's been so long since I did one that I'm not sure I have everything right. That includes the bypass cap for the midrange. The value I want doesn't seem available so I am looking at one either side. Either the 1.0 or the .68. Is everything else OK? It's an LR design

Please note the W and Mid are 16 ohm while the tweeter is 8.

Thanks for your help ahead of time,

Cal

Guess a pic would help

Parallel a .47 and a .33 for the cap you need.

Bill,

Thanks for the response. Did you happen to check the rest to see if I'm in the ballpark?

Well, it's a text book crossover and would be in ballpark if you had zobels across the mid and woof.

Thanks Bill. You're a pal. I needed to hear that.
I'll give 'er a tweak it after hearing the initial results.
I wasn't sure where to go, so I went here for my cap and coil values.
