Hi there,
I am trying to build tower Speakers for Home theater, Using 2X Dayton Audio RS150P-4 Ohm connected in series, RS100P-8 for Midrange and Tweeter DS28F-8.
Please help regarding the crossover design.

Hi!
It looks good although I'd improve 2 points:
1) little bump at 900Hz (no big deal)
2) impedance between 10k and 20k - depending on your amplifier, you might have issues dropping below 4ohms.
If you want to share the Xim file and the .zma/.frd, I can take a look on that.

Hello I would move your crossover frequencies both down a bit The woofer to mid is a little high for my taste and that mid-range drivers going up way too high I'd also bring the tweeter down, just remember to keep the inter driver spacing at about 2/3 of the wavelength of the crossover frequencies .I would also make the crossover slope higher on the tweeter circuit, it doesn't look right and you have a bump at the resonance of the tweeter. This is not good. Try an L C R notch across the tweeter terminals, in fact. You can dump the resistor and create a notch at the tweeters resonance, this works wonders on sound quality.
Hi!
I rebuilt your Xsim schematic with the drivers you told are using (X Dayton Audio RS150P-4 Ohm connected in series, RS100P-8 for Midrange and Tweeter DC28F-8). I didn't found the Dayton Audio DS28F-8, then I substitute with the DC28F-8 assuming that the "S" in DS28F-8 is a typo:
Please observe that the tweeter is also in "reverse" polarity connection, not only the midrange as per in your schematic.
The results I got with Xsim are as follows:
The system response looks to be flat enough but, when you look individually each band, you find that cutoff frequencies do not define well each band.
Analizing them with Vituix CAD, I found the following:
In my opinion you must try to get only two cutoff frequencies, as 400 Hz and 2000 Hz for example and have the same transfer functions for each band.
I know that it is a difficult task, but possible.
