Hi,

You're a quick DIY'r. Did you make a closed box or something else?

Submitting a picture containing more calculations.One of the results: One driver in a 300L closed box is not promising normal sub FR extension but only mid-bass BW, at most.

I made 1 320L box and there is 2 loudspekers.
Its vented and tuning at 40Hz

Tb46,what do you mean at jbel ss15?
Do you take some link?

[hents503]

Cubo 15
You think this box? Thats cool but big..
Can something like that but smaler?

the cubo 15 is 240 ltrs netto.
if you make that even smaller you wil lose lf extension ,or efficientie.
