Hi Neskor,
Thanks for your tip. Never heard of this model before. It look simple in its construction. Do you know where to find (if possible) the construction drawings/messurements?
Once again thanks!
Ps. Maybe there is other boxes which allows even deeper bass than 25Hz?...

Hi Neskor,
Hope all is well. I am using cad cam and sorting out all bits n pcs which needs to be cut out. The speakers look like are positioned to close to the edge of the baffle. When you say 9" do you mean from the edge of the speaker or do you mean the edge of the buffle?

Please have a look at brace solution. As I am joining the braces for maximal support I gain volume. I am no expert at this but do you adjust the vent´s length or diameter for compensation?

Here I uploaded an animation of the box. As you will see the woofer wholes look to close. When the 2235 is in place it´s appr 10 mm to the end of the baffle...
I will be happy to provide you with all illustrations and measurements of the different pcs.
Look forward to your reply!

I think that is a 9" from the up edge of the speaker.
So you have, center of a speaker is 15"/2= 7.5" and you have 1.5" left to get 9". So you should have 1.5" from the edge of a speaker frame to the edge of a speaker cabinet.
Check the bracing here:

Hi Niklas,
Measurements in home environment I did (over two years ago) might be of interest: http://www.diyaudio.com/forums/multi-way/160452-why-no-bass-8.html#post2077912
Edit: Link text "why no bass" might be misleading

Hej Anders!
Gött o se blågul färg på flaggan Dina mätningar var ju inte så tråkiga om man säger så
Alla som finns här på detta forum är ju proffesorer... jag känner mig inte riktigt på samma nivå. Vilken låda körde ni elementen i? Har du ngn ritning på den? Jag har precis blivit klar med ritningen på B380:an fast jag kör 2x15" i två subbar. Jag vill ha bra tryck och bra dynamik. Till mina basar kör jag 6290. Jag har inte skaffat det aktiva filtret ännu men funderar på dbx. Som toppar har jag moddade 4425 (ett företag i Tyskland som konfigurera om dom så att de är aktiva. Kallas nu 6425)
Tacksam för lite hjälp
