Hello,
I posted a thread recently regarding a sealed 2-way all Dayton build (with 1" and 8" drivers) and I got a lot of help. Thanks a lot for that! As an alternative to that project, I started working on another sealed build with RST28F-4 and dual RS125P-8. It is for my 5.1 living room setup which has an 11" sealed sub. I would like to share with you some screenshots (crossover and full space response with diffraction) and it would be great to get your feedback knowing I am a beginner. My main questions are:
1- Is my design realist?
2- Do you see any flaws in the simulation?
Thanks in advance.

What are you trying to achieve?
Will these be the sorround? Or mains too?
Can I recommend something with Markaudio full ranges?

Hi Aillo,
some of your problems are:
some of your problems are:
- you only have 50mm between woofer center and tweeter center. They need about 120mm.
- That big dip at 2KHz is going to sound bad.
- The second woofer is crossed over too high. You don't really have a 2.5-way design. It's more of a 2-way design with 2 woofers
- Impedance is a bit low- down to 3R at one point.
@alexdaciuk, I am trying to design new main speakers for my home cinema, where I also listen to music. I want sealed speakers, so first I tried 1" and 8" combination (xover point around 1750hz). As an alternative to that project, I am trying a dual 5" this time, hoping I might get better mid range out of it. You are welcome to suggest anything. Thanks!
Thanks a lot @ByronInPortland, this helps me a lot. I have some questions for you:
1- I am having difficulty in understanding how the distance setting work in VituixCAD. Is it calculated from the middle of the driver? Also, how would this affect the diffraction simulation where you can chose the position of the microphone?
2- You achieved in setting the speaker to 5 ohm minimum impedance, but I am using nominal 4 ohm speakers in my home cinema. Most of them go down to 3 ohm, which is why I thought it should be ok. What do you think?

Reference angle is on the center of Tweeter axis: ex. T (0,0,0), W1 (0,-140,0), W2 (0,-280,0). In diffraction tool the mic should be on the center of the different drivers as you will set the distances in the main program. Also read this pdf file when using multiple drivers.

I change the X, Y, Z position of the drivers in the Crossover tab. It's in the table in the bottom left of your screen.
The minimum impedance of your speakers depends on what your amplifier can handle, and may be in your amplifier's specs. Not many power amps perform well with a 3 ohm load.
