Collaborative Tapped horn project - Page 61

Hi ,
Built my other trapped horn today.now I have STEReO sub
here is the curve from Hornresp.

Its the best I could do with this driver (Perless Resolution 10) in 20 tryouts...?

I wonder if someone with experience of building these type of horn could tell me if it looks OK?

I sounds ok ..the peaks above 100hz is not disturbing and for the moment I have 2 conical pipes with a 6db lp passive filter at 50hz and for a room 60m2, I only use 1W and 10W at the peak.

I use these with Open baffles at the moment.

the sound is WERY loud and very clean and deep

VERY physical bass with volume above live level.
very open and Airy sounds almost as good to Heavy orck and ,Bjork as with jazz and acoustic music.
I used to have Jensen "Onken" 200litres box with 15" and thats was the best bass i had until now.
These are as good as the great klipsh cornerhorn and other big horn I have heard.
Its easy to become a bassfreak and overlevel these boxes..

That graph is unreadable

it is roughly flat from 30hz-100hz as far as i can make out

i would like to learn how to design horns is there a guide available on how to use the horn response program because all i see is a load of letter combinations that make little sense. basically it looks baffling at first but is probably simple when you learn it

thanks

thanks great looking guide carnt wait to get crackng

has anyone heard about those fan sub woofers? i think they only work as IF but in a horn u could blow a house down

Take a look at the articles on the Danley Sound Labs web site and read the one about the SBG - the Sonic Boom generator (an Intersonics project for a government contract). It uses six 5 HP fans and a servomotor-controlled rotary valve to generate its acoustic output. This is off topic, but it deals with what you suggested - the fan subwoofer in a horn-type thing.

Wow the thread has become so Big ! After reading a few posts of those who have built this sub i am very interested in building this sub.
May i know which S1, S2, S3 ,S4 and the con ? It would really help if someone could point where or draw on the pic below to show where these lengths are in a tapped horn.

1. In the above pic is S3=L34 ?
2. Where is S4 suppose to be ?
3. S2 is the length from the back of the cone to the opening right ?
4. The blue line which is L23 is it suppose to be parallel to something and the how is the angle of the part indicated by pink arrow determined ?
