G'day soundNERD

If you want to build a 40Hz bass horn with a 4" driver, you'll have to start from scratch. Be aware that a 40Hz bass horn with 4" driver will be MUCH bigger than a similar horn with two 10"s or a 15". The required path length would be very long and the folding would be complex. Why don't you use your 10"s?????

cowan audio you must be pretty much sick of this thread!

i noticed that the eminence delta lf has a high qes, close to .7!!

how does a higher QES affect the hornloading proscess? alter FR? reduce powerhandling? im kinda in the dark.

if youre feeling reallllly nice, you could always link me to some places where i can learn some of this stuff for myself.(i have tonnes of time, i never do my homework )

Yeah, it's going that way

>i noticed that the eminence delta lf has a high qes, close to .7!!

It's funny what comes out in the wash. No substitute for running a model.

Play with horn response

Read Marshall Leach's paper on horn design

Read the Labhorn thread at: http://srforums.prosoundweb.com/index.php/f/3/0 specificly posts by Tom Danley

Build some horns and measure them.

> i never do my homework )

Yes you do, just not what your teacher wants you to do

ok ONE LAST QUESTION!

it has to do with modelling drivers.

when i tried to copy your hornresp window settings into my program to run simulations....some of the fields were different and i could get it to model right. whats up with that?

no the atual name of the field i need to put the data into does not correspond to your horn resp window on your site, so i cant model it.
