Great information here.
I am going to try and build a pair of CornScala's myself.
Personally
I like the slimmer profile, and was going to build a pair with the
basebin dimensions being 21.5 wide, 21.5 deep, and 28 high, this should
give the interior volume 6.2 cu. ft.
Now for the port shelf, if
I am understanding this correctly the port needs a cross-sectional area
of between 70 and 75 cu in. and if the interior width of the cabinet is
20 in. and I make the support board for the shelf the enitre height of
the port that makes the width of the port 18.5 inches wide, and if the
port is 4 in high 4x18.5 is 74 cu. in.
The port shelf length remains 9.5 in.
I
hope that these calculations aren't wrong in any way, because I plan
on starting this project really soon. And if the they ARE wrong that
someone will chime in and revise them for me.
A bit more insight about the speakers, they will be split top design.
I
will be using Crites Speakers CW1526C Cast Frame Woofers, Altecs 811
horns which I already have, Great Plains Audio 902, and JBL 2404H baby
cheeks which I also already have, ALK Engineering crossovers.
Thanks. Brian.
