can u just go into a store in US and buy a book on horn loudspeaker design? or is the best still in certain magazines and online.....

because there isnt anything here in NZ im relying on the internet

i could order AES,although i would want them all (one wouldnt seem worthwhile), or some and then i dont want ones i dont want....lol

my midbasshorn ,its at the end of modeling it is now being folded and optimised spacewise.~!

i Could remodel it again with what it has Now,but i cant really be bothered-
its just an experiment,and i expect it to be 'close enough'.
modeling folds?hmmmm

because ive just completed my 2week holiday( and finished completeling the modeling),and my mates relative whos a woodworker is busy makn my mates bedroom like a sleepout,so wudve been busy.

this will be good to see if a 30hz 750L horn is justifiable

as soon as i finish the niggly bits-

the corner reflectors,completely optimising the rear chamber to be correct 17L+2L for lab12 woofer+bracing,

and drawing it more times in Qcad with really skinny lines

one of my problems is my little 14" monitor cant display it all at once! :P 800x600

this horn is for the Experience not for perfect response..250L only,
how can u go wrong :-P

im thinkn 25mm mdf always that rear chamber brace is infact vertical :*)

and then il get RS meter(with new mic like adrian has),test it outdoors,in car,in home,in corner,see if can squeese 40hz out of it with a few watts :-D

Cheers!

Keep us posted! I'm anxious to know how it sounds, and to see some photos in December when you've got 'em done!

i think the lab12 woofers high mass + le stops any HF above 200hz :P

it wont go any higher..but thats ok

300hz wudve been nice ,but really im not gona build another midbass bin just to reach my 300hz tractix horns i dont have ,and wont haev for a very long time :P

btw im getn a new pc (2ghz),so i can use hornresp and wait only 2seconds for the response ,rather than 30seconds on my 133mhz,for a hyperbolic horn =)

also ive noticed its just so much more productive having a pc that can run ur programs at a decent speed.

ive gotn in a few arguments in caraudio forums,ive posted 150posts in one forum and 50posts in the other,in a matter of 28days
,so much speaker truth to tell! so many lies made up things,unproven things,its really annoying,i think il leave it soon,just post to the ppl who are interested in learning.

but i like to think i told ppl some useful facts
theres alot of ppl who have heard boomy boxes such as the xxx18 pictured,many ppl seem to love that response..i told them IB or dipole it;P

cheers

:-)

lately ive looked at this site

http://www.klippel.de/pubs/nonlinaura.pdf
http://www.klippel.de/pubs/default.asp

wish i couldve seen that talk/AES full file!

:-D

the delta10inch extended flat..
notice that was when i was wanting 30hz..
now compromised for 40hz for enclosure 3x less volume

cheers
