an enclosure of 53 high,if the inside pannels of the horn are, lets say 50 cm ,you best divide it around the bends in 3?

This is good practice as well, particularly when extended beyond the bend.
Here are some examples of the passage bifurcation to which I refer:

Default MicroScoop ?

Hey guys, as some know it, even I have my 6 T48 Bill design, with which I am not happy in the sense that they do not fall over 50Hz and feel that life lacks the bass of the music.

Now I commented that I have 20 speakers 15 ", 6 of which I have in the T48 and 4 speakers I have a pair of HD215.

Some friends told me I could try the good TUBA36 and talked so much of the T48, that today and I have my doubts, for that reason, reading and looking at the forum, I read that Mr. Staiper says 12 MICROSCOOP ERS sound very well, what is not said is how many HZ are able to lose such microscoopers, because if they are within 50HZ, serious bass very similar to the T48 that I have.

Another possibility I see is to make super scooper with 2 speakers 15 "Super Scooper maybe with 1 double, I heard a super scooper 18".

The problem is that I have many speakers 15 "and for the moment I can not buy speakers 18", but if I would like to help me with their opinions, to choose a design for a 30Hz - 35Hz, and submit with my HD215.
