I.ve been schetching away one day, and came up with an interesting ideea

Imagine

it's a horn loaded mid top

1x12" P-audio C12-300MB
2x6.5" Eminence LA6-CBMR - CLOSED BACK 6.5" MID SPEAKER
2x1" driver probably P-audio WN-D44

I'll post a pic of the internal layout scetch

until then , I'm posting the mid-bass and mid plots

Mid horn: 2 pi (2 horns on one enclosure)
Imagine

midbass horn (2 horns in a horizontal or vertical array)
Imagine

the high frequency horn ideea came up when I seen the new horn P-audio had developed for line arrays

Imagine

The part I like is the fact that the mid-hi section can be couplet both verticaly and horizontaly to form any coverage necesary without too much comb filtering, if any

and of couse it's again extremely compact 8) , because It's my obsession :twisted:

That looks very good. I'd like to see some more detailed pictures.

Looks almost too good to be true at that size?

Yes I know , I can't belive it myself

and the good part is that the more enclosures togheter, the more smooth the response is :wink:

4 enclosures in a vertical array, would be extremely cheap, and would have a great coverage and SPL.

the HF and MF horns can be made of wood , relatively simple

I can't wait for the summer to come so I can start experimenting...

I'll scan the schetches as soon as I can

oh right!... i get it now.

i couldn't visualise the layout before... i like the figures too, although the high mid might give you something to work on.

I presume something like 60 degree horizontal and 20 vertical - depending of the waveguide

the interesting part is that if you put two boxes side by side with one of the units upside down the HF and MF sections will line up next to each other , thus coupling ang giving us a 90 degree dispersion, cool eh? :wink:

the design originated from a line array I was triyng to desigh, but I soon discovered that I was be able to split it into a pair of enclosures.

very very good design

i have just few questions about the mid high horn

-where did you find this p audio line horn because i know a shorter model model from b&c but i didn't find this one?
-do you want to build from wood this horn for the comp driver too
-finally i woold like to know where we can find the eminence driver

thanks a lot nexus
you drived me to this forum a few month ago when i would built a mid top with hd15 in it and i follow the topics since and i have understood a lot of things about horn loading

on www.paacoustic.com , it's one of the new products

-do you want to build from wood this horn for the comp driver too

Yes, i think wood will be more simple , and cheap
-finally i woold like to know where we can find the eminence driver

ask them:
http://www.laboitenoire.net/boite/grill ... 16&fam=251
they don't seem to have it on stock, but you can mail them and ask.

this makes me thinking...

how u can go low enough with wn d44 thus u will be able to reach to uppercut frequency of the mid horn?

its hard to cut a 1" driver under 2khz... a 2" driver should be a better option...

the mid section should easily reach 3 Khz
!! hornresp does not plot corectly higher in frequency, that's why the graph posted seems to fall so sharply.

a 2" driver is not an option because of the size

thanks a lot

i have just one suggestion that will not be aproved by nexus

why don't do it larger..

my idea is to have the mid high section on mobile area

i explain
to stack the cabs in more position why don't we place the mid high section in a square cab where we could displace it horizontaly or verticaly in fonction of the show
we could fix it with btr screw on a chassis and it would be easy to have the same dispersion when the cab is down or up.....

i have an idea about it but i don't have scanner to show you what i had in my mind
i will post it when!


another things :

why dont make it trapezoidal on the other side too with the same degrees

it will revolution the concept that you work for but it will be more easy to array in all positions

i have draw all of that but i couldn't model a horn in horn response i still haven't work on it
but the idea is here and the dimensions are tight from other product or try from this forum
thanks for your attention
i wil post it in a few days
jon
