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

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.

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..

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...

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.
