need help designing a 3-way crossover

[Jarryd]

I am seeing large dips and uneven distribution of SPL. im new to this and would like some help in designing this

[bwaslo]

You have C2, L2 and L4 shorted, so there's no crossover at all on S2, S3 and S4!

[Jarryd]

i just checked, there is a separate "short" option available. this isn't shorted from what i checked

[Jarryd]

@bwaslo what do i change?

[bwaslo]

You have a wire drawn through the center of the parts. Move the part aside, delete the wire, put the part back and don't connect one part's end to it's other end!

[Jarryd]

Thank you bwaslo
i have made the changes, how do i flatten the response and impedance curve further?

[AllenB]

If you made for example, C2 smaller and/or L5 larger you'd see the mid driver peak near 400Hz reduced. Maybe try making L2 smaller for the mid driver top end. See if you can give them a little more symmetry as this makes it easier. Have a play with it.

[Jarryd]

Would this be considered an ideal response, i have gone with a 3 way 2nd order crossover. As you can see i have modeled the bandpass with out inverting polarity. I saw a slight peak in impedance at 250hz, can somebody help me remedy this.I am new to this, can you please check the frequency and impedance response and tell me if its proper so i can go ahead with fabrication

The drivers used are as follows,

Tweeter-Dayton Audio PT2C-8 Planar Tweeter

Midrange - Dayton Audio DC50FA-8 Classic Series 2" Dome Midrange

Woofer- Dayton Audio DC300-8 12" Classic Woofer (using 2 woofers in paralle)

Going for a TMWW configuration

[Jarryd]

i have arrived at this design. but why does the impedance drop to 2 ohms? the woofers which are individual 8 ohms, will be wired in parallel, have i incorporated that into the design?

Give me 24h and I'll see what can be done to make the crossover simple and easy on the funds.
