Hi all, this night an idea explode in my mind. Why don't we create a simulation database for hornresp (and akabak and winisd as well) ? Some people do the same for hd15 check this thread http://www.speakerplans.com/forum/forum_posts.asp?TID=2617 I mean only the horn specs not the driver, I think it could be so useful for all the builders. The hd15 sims thread it's great but I think is not so reliable, putting the screenshot of data window take so much space, it's better raw text, it's only a cut & paste frome hornresp.dat ;) What do you think about it? |

Posted By: bitzo

|
this is the main trouble! I start measuring horn lenght from the end of the driver, the front of the driver is the compression chamber. But, if there's a letter box throat I start measuring from the middle of the areas of the letter box. I use datainf measure software and inkscape for the measurement. |

Thought these should be in here: X1 bandpass cabinet measurements taken from the plans on the main site. Front chamber tuned lower:
S1=684
S2=684
con=43.50
vrc=62
lrc=50.40
ap=684
lpt=26
vtc=189000
atc=2520
Front chamber higher tuned:
S1=684
S2=684
con=26
vrc=189 lrc=50.40
ap=684
lpt=43.50
vtc=62000
atc=2520 IMPORTANT: As with all ported things, when you simulate this, at the SPL response page, you have to select combined response from the drop down menu (Tools) and set it to zero. Also, port lengths are physical, in reality due to the X1 being on the floor and end correction, the X1 will go a bit lower than it seems. Check with Rog's graphs on the plans and when the ports are the right length, they should look about the same (model and graph). ------------- Away on extended leave. |

But what's wrong with wanting to replace a blown driver in an AB-36 you already own with a different driver, say a PAudio SD18, but you want to model it's response to see how well it would work first... I believe the whole copyright issue is to prevent people from making money off a patented design. Once your product is out, there's nothing stopping anyone from taking a tape measure to the insides and simulating a response... I'm sure many aspects of QSC's amps are patented, but they make repair schematics available on their website. ------------- http://bitcore.org/stuff/Bass_Tones/ - Bass Tones & Sweeps in 160kbit MP3 http://youtube.com/watch?v=mC9XqmyKaOY - I<3bass

when cerwin vega release its plans on its site, I'll post the simulation...however you can find the plans on the net and you can try to do the simulation by yourself. It's not harder, I use inkscape openoffice calc to get the data from the plans, free tool you have only to try mate :) |

greeting Lasse. Just a couple of suggestion IMHO Eg and Rg are always the same and they don't change if you change cab. fta, f12 ecc are calulated by hornresp so are'nt a sensible data but... could be useful for a database search engine An idea blame in my mind.... could you write a script who download the driver's data from www.thielesmall.com? cheers, bitzo |

The search will be improved as soon as i have time. Users will be able to search every field in the database. For example all designs that go down to some frequency etc. I'm afraid that thielesmall.com doesn't have any kind of API that i could use to access their database. I'll contact them and ask. Thanks for the feedback. |

I was always under the impression that a simulation isn't always accurate to real world measurements, so whilst we can see that the LAB measures closely to the sims, it's not yet known if the DEMO1 does unless you've got some real measurements done yet mykey? Looks to be an utter beast of a sub if it does though! |

cheers guys
heres a pic, almost bottom of page
specs look better than the EM quake, which I'm happy about, and originaly set out to do was design something similar
I believe its a longer horn too, so they will have to take off their qoute from their website

Looks great mykey.. what are the dimensions?
I like large format horns... still don't understand how Rog is gettin 147db with a quad stack..
|
Posted By: mykey
Date Posted: 18 January 2009 at 4:30am
|
quad stack of staceys would be 8 drivers
is that the cab you are talking about?
2 ft high 4ft deep 4ft wide, 10 ft horn
the only way to describe the sound is a hifi reflex low, amplified by a 10ft horn ------------- ......just all them hanging there like giant bananas. |

Nice, same size as Z-5000 and the like (and i think LABs)
I'm referring to the psyco.

With my limited skills i can get 146db with 32Hz f3 with 4 x 850litre enclosure, Rog has managed 147db with 29Hz f3 with 4 x 600 litre.

try puting 4800 watts into the sim like the above link
you may find you get more than 146
I'll try it into the Demo1 ------------- ......just all them hanging there like giant bananas. |

Someone has parameters for ESW 1018 ? Thanks |

| post the plans if it's not copyrighted yet. However you can obtain the paramaters by yourself. It's easy to learn how do that. |

isn't this question wrong?
