Is any of these 2 xover technically preferable?

I used an SB26 tweeter the waveguided one to give approx 95dB sensitivity. I know Jawen did post some tweeter data but it was not easily traceable and there was also a small amount of tabulated data, consequently I took the easy way out and substituted the SB26WG and used SPL trace for the 0 degree axis from the data sheet. I guess if anyone has the Audax FRD and ZMA it could be updated with the correct tweeter data.

I did this some weeks ago in the early part of Jawens Journey with this project. I do chat to Jawen, so I have not been withholding any information from him.

Hi again Ray

This was the first you send me (that inclueding xover box)
But it doesen´t look the same as these you posted now without xover box?

The only way I can think of that would cause your off axis to look different from raymondj, is that you might have entered different driver diameters in the software. A 2" will be strong off axis. A 12" will not. Make some changes in the sim, and observe.

Feels like we don´t use same settings Raymondj and i ?
For FRD & ZMA i don´t know.

Something is different for sure.

Good night from Sweden it´s 1 a clock in the night now.

Hi Jawen,

I haven't got much time this morning to go over questions, I think we can guarantee that there will be small differences between individual results, mistyping positions being an obvious one along with the application of VituixCAD. I am still learning that one.

The data in your latest post is my first basic sim,
I think it was an estimates of driver positions and by the multiple ripples in the frequency response I think it was using a simulated driver dimensions for the FSL Peerless data, and maybe show affects of inductance when i used the enclosure tool.
I think that is why there is an emerging flower petal thingy around 1-2khz. Also at that time not knowing the tweeter I used a standard tweeter and boosted its output with the amplifier. You can see how this affects the phase and impedance graphs at approx. 4Khz

The last sim I posted #53 was with my latest understanding of your design. it uses simulated data for each of the 8 FSL drivers, hopefully at the correct position on the baffle. I will take your latest FRD and ZMA and add them into the mix.
