The DubHorn:Wi's TC 5100NEO loaded 20hz horn.

[Wisounds]

Yep, it is officially that time. I have found my driver, now I will make a horn around it. New ground up FLH design. This thread is intended to chronicle the process from conception, through prototyping, to final design.


Design goals:

>Horn loading to 20hz
>Load with a single TC Sounds 5100NEO
>140db @ 20hz Half Space with 4 cabs/4kw or less

****Uber Super Special Thanks to maxmercy for he is the HornResp Don, and without him this would not be possible****




Here is the initial trace. Grey is one cab, Black is 3. 1kw to each driver, half space.



Expect more updates randomly over the next cpl of months...






I want flat to 20hz, as loud as can be from one or 2 20A 120v circuits. I draw 3kw now, if I can beat the THTs by 10db at 20hz(real figure BTW) I'll win even more.

A $1200 driver? last time I was just concerned with reusing your JL's....

BTW, one critical missing piece... how big/heavy per cabinet?

Looks like a permanent installation. i guess something aroung 1000liters.

Edit: 1) This driver isnt exactly what one would call "cost-effective". You could get better performance for less money. 2) Front loaded horns tend to perform worse than tapped horns as long as the mouth size is small. For a single sub, especially for a 20hz one, tapped horns can give great performance in much smaller sizes.

you don't know Wi, like some of us... this is not a permanent installation, he's likely to use these in a living room party..... or in his vehicle.. He cracked a windshield in his explorer once..

lol, i guess the project can be worthwhile with the appropriate level of fanaticism

fanaticism is the CORRECT word for Wi. He wants what he wants, and trying to talk him into something else is a waste of time. His standards are high, and I'm not sure in a quick sim that I can do what he asks. I have to sim in 1pi wall loading to get there on my first attempt.

hmmm...

jbell, my friend, been far too long.

These cabs are going to replace my THTs.



Time to post my intro thread here I guess. hehe

That is arguable, but I have to wait till the paperwork is signed.

In a direct comparo, the TH gives a bit more at 20-30 but sacrifices above 40.

Here is a TH vs FLH graph.

TH is grey, FLH is black. Hence my choice of open back FLH.
