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 email address is being protected from spambots. You need JavaScript enabled to view it.. For free. If you have any problems, inquiry or any suggestions,

don’t hesitate & feel free to ask. We are always there for you. Thanks, Prashant.

Has anyone built these recently? Interested to know how they went.
Also any other drivers anyone could recommend for them?

Looks like a PWG to me... the bit infront of the drivers is probably more of a chamber than a horn.

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?
