RCF 21 Tapped horn

Hi everyone for the past few months I want to upgrade my sound system so I download horn response and give it a try , boy this thing is hard. Anyway with all the talk about tapped horn I said to myself I want to try something new enough with scoop, so I plug some numbers from the RCF21 driver in to horn response and get this

Epa design

My gold is to put 950 watt in the driver before reaching xmax.
My cabinet size is 45”x45’’x30’’
Frequency range 35hz to 110-20hz flat
The design I have in mind belongs to Epa .

Also if someone could help me with the folding that would be great. I have no knowledge of folding.
Please feel free to make any correction to this project.

Thanks

A little help goes along way

are you shure about the size.
thats about 1000 ltrs.

thats much more efficient than your sim.
x-max is 8mm?
i did a sim that gives you 129db @8mm x-max with a peak of +130 db @38hz 750 ltr cab

olsound · 31st May 2011, 02:38 PM

1000ltrs that is big. Can we get 140-145db with 4 cabinet
