Hi Oliver !
I had not seen your answer, and I answered myself ......:D
Correct reasoning, we agree 100%.
Thanks for the pictures.
Congratulations on the new box, I see other JBL speakers there!...
The answer is to change the length and diameter of the tube, the Fb (tuning frequency of the box) moved below

They look great now! Congratulations !
I see you used my method of "painting" exlusiva rejuvenating , and the same wings,...
Hi hoschibil
On treatment with brake fluid (do not share the idea, because if you alter the parameters of the speaker softening the wing, to change the fs, you must also change the tuning of the...
