You do not need a stereo and two loudspeakers
You can simply use one paging horn to transmit your signal
This will work just fine for you
If you want to use two of them so be it but try one out here before
you go

Besides the paging horn having extreme high output with little power you
should know this unit is weather proof and rain proof. This unit will
survive the rain, and heat and weather and you can even leave it out in the rain and it wont hurt it. Also, this unit weighs 5lbs and will run as
an 8ohm load.
Bandwidth 300hz-14,000hz
Thanks for the help! As I mentioned before, I'm concerned that the sound quality of the bull horn won't be good enough. Is this a legitimate worry or will the sound quality be fine with the horn?
It will work fine
You can understand the human voice well through it cant you?
I work at a University and one of the biology guys took something
similar but smaller and mounted it to his car and had a device inside
the car that fed a signal that sounded like branches breaking or something like that and it scared deer away for miles while driving on the back roads
With the distance and output you need this bull horn will work well
and the weight and size and weatherproof is all a plus for you
Also, you can run this thing on 10 watts and it will give you huge output
You can have a little amp on batteries and drive the horn for a long time
Hes not looking to reproduce the human voice the bull horn will not work well in the range he needs.
What is the bandwidth he needs?
I looked up bandwidth of bird calls and several go far lower then just
a compression driver alone will handle
Get the frequency bandwidth involved here before you just send the guy
a compression driver
:)
Examples
1. Canvas-back--190to 5200 c.p.s.
2. Great Horned Owl--60 to 7000 c.p.s.
$. Horned Lark (av.)--$50 to 7600 c.p.s.
4. Snow Bunting-400 to 7200 c.p.s.
3000HZ and above is what hes asking read his post. Why keep asking me for info the gent posted?
Where do you see 3000hz and above?
I see 3000hz
Nothing above and nothing below
Not 3000hz-20,000hz
I need speakers to broadcast high frequency (~3000hz) animal vocalizations over long distances
What you are saying is it only has to reproduce a 3000hz tone?
What is the bandwidth needed?
An animal sound covers a certain bandwidth
No animal just blurts out a 3000hz pure tone
Read his post 3000hz and above
Hi Kloss
I read one of OP's posts and it mentioned bonobos....
This is a primate
Can you see what I mean about finding out what animals he wants
to project through this sound system?
If indeed he is talking about a primate then you have to have a large
bandwidth loudspeaker/horn system to project a primates vocal range
Sorry, and I am not trying to be anal here but there is some information
that is lacking from the OP.
The post about bonobos is below inmate51's post
