MTM w/ND20FB and TC9FD for pc speakers

Question for the forum.
I am going to make a sealed version of the Nola brio/trio clone + tweeters for pc speakers. Found them on a thread of a similar name.

I plan to use 2 ND20FB-4 and a TC9FD-8 with 3.3 cap and .2mh coil. Box w/ .5”,mdf roughly 15” high 4” wide by 7” deep.

Running a dragonfly dac to a 2.1 plate amp (30 watts for r/l) that is highpassed at 100hz and a small sub (Voxel?) from about 150hz down.

Everything seems reasonable to purchase parts and begin.
Any modifications or improvements anyone would suggest?
Is this a good application for pc speakers?
I also looked at the helium micro monitors as well.

Thank you.
Jeremy
 
Make sure you make your baffle as close to the one by Adason if you want to keep that simple XO.
Adason's baffle:

Here is Adason's XO:

My temporary baffle:

I deviated a bit on the spacing and used an ND25FA-4 and was not able to use the same XO but ended up with this:
870738d1598391164-mtm-tc9fd-nautaloss-dual-tc9fd-nd25fa-xo-schematic-jpg


My measured XO response:
870740d1598391164-mtm-tc9fd-nautaloss-dual-tc9fd-nd25fa-4-freq-meas-xo-jpg


Curious why you didn't just post in his thread rather than starting a new thread?
