horn loaded speakers and panel placement

[abjonesiii]

hey guys,

I have a questions. I just finished building some acoustic panels for my theater room and need a little help with placement. I know where I'm suppose to place them but i kinda don't know at the same time. I have been searching forums and numerous website with not much results.

So, where are the first reflection points for horn loaded speakers (klipsch) ?? I know with most speakers the mirror trick answers the question but with horn loaded i know its different. I've read a few post that reference the FR as being further back but i can't find any science to guide me on exact placement.

For reference my room is 26 x 13 x 8 with vaulted ceilings starting at about 4 feet up the 26 foot walls leveling off at the top with about a 7 foot flat ceiling.

I definitely have a flutter echo and I'd like to flatten out frequency response (though i don't currently have a way to measure that).

thanks in advance!

Hey,

Try puting them @ the first reflection points.
Lean them on the wall or use something like a stool to place them at the proper height.

Proper placement usually takes trial and error.
Place in different locations. Turn on the tunes or use the clap test and listen for the sound that pleases or where the echo is diminished .

For flutter echo. The hand clap test works or the bic lighter flick also works.
A bass trap on the front wall placed @ a 45deg angle touching the ceiling will help by eleminating the relection that bounces off the rear wall.
The majority of reflections will bunch into the corners.
That is your flutter/echo.
You don't have to cover the whole corner.
