Hello & Question about "Basta!"

[Promettez]

Hi (c:
I'm french, Full Range liker and Im glad to be on this forum.
These days I try to build 2 parallel on-wall enclosures, bass reflex, for the Fostex FF165Wk.
Of course I want to limitate baffle step, and I try some simulations on Basta!, with the 'Baffle designer' tool.


My enclosures will be H74xL23cm, and 16.6cm deep.
When I check the baffle/wall distance on the "Baffle designer", do I have to enter 0 mm, or do I count the 166mm enclosure deepness?
Does 0 mm means it is "in-wall"?


Here's a screen shot to explain (I put 1 mm in this exemple).



Thanks in advance!
Nicolas

I would use 166 as B-W distance.

Thanks TNT, that's what I found too after some other searches here.
Disapointing, because 166mm away from the wall makes a dip around 300 HZ -so byebye nice flat response- but in a way it's logic, there are still corners, so baffle step is here.

Yes - the same as for the floor bounce I'm afraid. No free lunches as usual 😉

On wall speaker should have a special baffle. A normal box near a wall can be bad, as you can see.

Yes AllenB, I guess it has to be as rounded as possible. The room I want to use these ff165wk is small, so I wanted a flat enclosure closed to the wall. But maybe I should use the room's corners with a simple MLTL or BR enclosure, and basta... (c:
