Hi
simulation with ajhorn looks fine !
Red: Seas in 73liter conical HornReflex as above
Drak Green. Seas in nikko03 horn

Hi Nikko
while thinking about your horn ...
it is close to a Replikon - horn ! The only difference: this is a straight horn to the bottom, Replikon uses curved ones to the front.
The authors of Replikon horn gave a rule by thumb for their horns:
take Volume for closed box with Qt = 0,8
Double this Volume for BR (this volume is something around a Thiele-Small alignment)
add 10 to 20 % (because of large apparture from horn)
construct a horn
the Qt=0,8 Volume is around 35Liter for the Seas driver...
this may result in your 80 liters.
well done. I hope, it sounds satisfying ! 😉
I have to say thank you for outstanding help and this gives me hope for my project in the future
My drivers arrived from Hasaudio last week. Nice! Should be able to try them in my OB's within the next week or so.
Hi Nikko
for simulations I use ajhorn in the version 5.0
Version 6 is avaible now.

Try this tipe of box with the Seas

That is a link to your personal computer. You have to upload the file to diyaudio.com
I am sure there is a manual on diyaudio that explains how this is done.
Sincerely

A picture of my testbox constructed after the drawing i have posted
I am very near satisfied with the sound. Very good bass respons and the midrange is clear. A little bit hard in the top range, but i guess i will sort that out in the xover.
I only have the H6 clone to compare with and i would say the h6 stops and starts more presise.
My fullrange is a bit slower but it has a mighty bass respons and a rich soundstage
So i am very satisfied with my prosject 🙂

oooh ! Well done, Niko !
Would things change, if you modify the distance floor / bottom Box ?
So giving the horn a bit more space to breath ?
Thanks Joern
Maybee🙂
I have a plan to mount some feet under there too regulate the height from the floor.
for now i just have to use some wood bits too regulate the height.
You see i am just finished with them and i have a lot of experimenting left
but thats just the fun part after my opinion🙂
And i have to paint the front baffel two or three times and put on som wax on the xfiner.
I really love DIY

It appears you use Martin Kings mathcad for designing MLTL if that's the case or do you know what the BL is for the seas Fa22RCZ?
Thanks

The grphs Scott shows are output from MJK, but he has a whole suite of tools he uses before. One of those, i believe, is a BL calculator.
