Hello guys. I am totally new with diy sound but i want to try to make my first custom speaker.
I know i am trying something very difficult for 1st project but i want to give it a shot.
I want to make a central channel for home theater.
I want it to be MTM style and particularly
woofer-midwoofer-tweeter-midwoofer-woofer. It will be a 3-way system.
I will use one tweeter: Monacor DT-28N 1-1/8" Dome Tweeter With Waveguide
two midwoofers: Dayton Audio RS125T-8 5" Reference Woofer Truncated Frame
2 woofers: Dayton Audio DC160-8 6-1/2" Classic Woofer (i would prefer to go with the reference but i cant find it in stock)
The crossover points i will use are 375Hz-3000Hz (or maybe i will change it to 3500Hz to be more safe for the fs).
I have designed a crossover in xsim but there is a range where the impendance drops a little below 4 ohms and i am afraid for my amplifier.
Is it going to be a problem? I haven denon 2700h.
I attach some photos of the system in xsim (2 possibilities).
Do you have any advice?
For the drivers or the crossover? Should i change something?
I want to have something to start with and then i will improve it.
Thank you!

What is the height limit for your center speaker cabinet? Can you fit a vertical T-M alignment plus side-side woofers?
--Are you putting the 5" midranges into a horizontal MTM alignment in order to reduce height below the more common vertical T-M alignment?
----There are small diameter dome tweeters which use NdFeB magnets and do not have a faceplate.
----Several dome tweeters have a plastic faceplate which is easy to trim in order to reduce the height.
----A few midrange have two "flat-cut" frame edges for shorter vertical requirements.

My height limit for center channel is 20cm , about 7.87 inches.
I now consider going a setup like klipsch rp-504c.
Using 4 same drivers for low and mid. I think 3 way is not the best idea for my case as i can not fit larger than 6 inches woofers. I consider using tang band w5-704d 5 1/4" and the tweeter i mentioned.
With my design now in xsim i get a peak in impedance reaching 17ohm. Will this be a problem. This peak does not originate from the drivers but from the crossover design i think.
