Comments from designer: Hi everybody, Hey this is prashant from India. I am a sound engg student in Mumbai.

I have made some speaker design; also I have made a NEW Dual 18” folded horn speaker cabinet.

After completed R&D we have give it to 54 Hirer for testing purpose. When they connected In open Air, Sound (punch)

comes near very hard & long soft tone. They played 12hr continually there was no problem found. I have used in

inside enclosure 2 x RCF LF18N451-1500watts RMS. & also used 2 x PD1850. If u wants this design

so please mail me:- This e-mail address is being protected from spambots. You need JavaScript enabled to view it . For free. If you have any problems, inquiry or any suggestions,

iiinteresting!!

A dual ported horn... not see anything quite like that before, i suppose a ported W-bin is similer in actual design theory... but still... very interesting

Any plots been made yet?
Looks like a PWG to me... the bit infront of the drivers is probably more of a chamber than a horn.
how to make a simulation of this box
