9" Morel in a sealed box

[msh1999]

Hi there

I hope im in the right forum for this,
Got a pair of morel MW265 and 267 and the plan is either make -a pair subwoofers or part of my 4 way design (crossed at 500hz) using one of the pairs, although the 267 is in favor since its simply a better driver.



the goal is reaching 30hz before the roll off... but in a sealed box.
from what i have seen around 50hz is the limit for a sealed design with these woofer, but i want to make sure.
so, is it possible?

You can use WinISD or Hornresp (steeper learning curve) to figure this out.

FWIW, sealed boxes don't have a "limit" as such - they can produce 1Hz, although usually only fairly quietly.

I got WinISD but either im doing something wrong or the driver simply gonna roll off at 100hz no matter what I do as long as its in a sealed box.

also should have mentioned that I dont have much knowledge in these stuff in the first place
which was why i opened this thread

The 267 doesn't favor sealed or vented. A vented box doesn't look bad but is a more advanced build. I wouldn't use them for a sub.

If its not a good idea it doesnt necessarily needs to be a sub then, it can be used as a midbass but the goal is reaching 30hz properly. with the cabinet i got atm (of about 45liter) they reach until 50hz, after that they have extreme roll-off.
I just want to get the most of this driver in a sealed design but im not sure if its possible since i dont have the knowledge (which is why i rather go for sealed because i dont know how to plan a vented box.

I don't have any experience with WinlSD WinISD - Linearteam it's free and is recommended often and plenty of YouTube tutorials. Another thought is use them for your main speakers sealed and add a sub.

The best sealed volume for 265 is 21liters and 267 13.5 liters. The good thing about sealed boxes is they are more forgiving in box size.

The t/s parameters and the construction of the Morel drivers are very close to Dynaudio 24w75 and the older 22w75, with the same size of the voice coil, hexatech technology and other Dynaudio stuff. There is a lot of diy projects with those Dynaudio drivers, just google.

For a subwoofer with 9’ Morel, my choice would be TL

thats extremely small, doing it would make the opposite of what im trying to achieve, are there any benefits of doing so other then having a smaller sized speaker?

isnt making TL design is of the hardest to plan?

but I know what u mean, I got 2 way morel with 6.5" midbass in a TL that pretty much can go down 30hz ,pretty sure that even lower in the right placement, (i should measure that) , long ago I even had 2 pair of these stacked for the sport (morel stuff can get extremely cheap here sometimes), bass was probably 20DB+ , shame i didnt have a mic back then.

about the dynaudio, from what i have seen around the forum the 24w75 likes to sit in a sealed 80-110liter box?
hell, i can do that but someone here just suggested 13liter box so im starting to get confused.

I used bass box pro and the database specs were wrong. New simulation for MW265

 

[oldmanaudio]

MW267

thanks! I got the right size cabinets for the MW265 already, Might will get cabinets for the mw267 as well
