I emailed this to Bill Fitzmaurice initially, and got an autoresponse saying I had to post it in his forum.
It wanted me to register first.

So, here is the question I sent to Bill.

Bill, thank you for all the support you provide to us audiophiles on
Audio Asylum and other Internet Forums. Â I picked up some old
Frazier Dixielander folded horn speakers that came out of an old movie
theatre. Here is a picture of one. Â I planned to sell off the wooden
horns and compression drivers, and wanted to explore if the folded horn
boxes could be used in a car trunk for my kids ? Â The drivers in
there are look like either an 8 or a 10, paper cone, looks like an old Quam
speaker if you recall them ? Â I do not know what the low freq cut
off of this folded horn box is, and if it would be low enough for my
kids rap music use ? Â I have my doubts if the stock driver will take
Rap either ?  How does one calculate the low end cut off of a
folded horn box ? Â I know you make a bass tuba, and know what it takes to
make kids happy. Â Think I have a chance with the right driver of
making these work for my kids ? Â Â
