just did a sim using the inputs for horn resp[onse posted I believe by bitzo on the data base thread.
basicaly take the 1850 horn inputs.....
divide by 3 and times by two on everything [we are planning on using the 12" sb30 just for horn response modeling purposes]
errrrr and now sim a stack of six [ie times all inputs except lengths by 6 and set driver arrangement to 2 in series and 3 parralel]
now sim this in 2pi with the sb30 12" by pd..........
errrrrrr am i missing something? 65ish hz< say 180hz seems prety impressive for 6 drivers costin say £85 each and needing say 3 channels of 1kw at 4ohm amping.....
have I missed something? or have I stumbled upon an idea for smaller [ie large small/medium small ish rig] type systems where 3 channels of 1kw at 4ohm 60<160ish hz with say a pair of 15/18 reflex to cover that last octave and say a pair of x10 could be nice for a small multi purpose system?
sory that graph looks far toooooo good for how much itd cost to build :P
any one else? [even if no one has any input but sees what I just saw.. Im sure if its as goos as I see someone would have done it allready...]

not by me, I only copy the HR input's screenshot from kpippen. Hr now have the offset arrangement so should be better modify the input in that way. ------------- http://www.unitedroots.it - United Roots SoundSystem site |

yeah Im using horn response v28
still trying to work out how to use the offset a rrangement, I always thought the horn length was more liuke 1.5/1.6 meters than 2.1 as well.
but serously tho the result looks ni ce :P
how would you go about modding the inputs to suite the offset arrangement? ------------- insert silly sentence here |

now I can't fell confortable using HR. Akabak is really better to resize/tuning cab, you have to make a dynamic model of cab and akabak model the horn for you. something like my cubo12 script.

Are you using that crap plots for a straight horn? I did once, but with my own measurements form the plan, it looked like hell, if using one cab. |

I didn't mean to be rude or anything :) Here is my hornresp numbers for 1850 and maybe if you scale it down you could get more accurate curves S1=660.00 S2=1044.00 Con=41.40 S2=1044.00 S3=1770.00 Con=64.30 S3=1770.00 S4=2760.00 Con=27.40 S4=2760.00 S5=4614.00 Con=23.00 Vrc=40.00 Lrc=27.00 Fr=0.00 Tal=0.00 Vtc=23000.00 Atc=1800.00 I think that it sounds like a cool idea to use 12" in those! Good luck! |
