Need Advice On Placing Absorption Panel On Ceiling

i have 4 echobuster panels on the ceiling. they (each) are about the size of a door- i.e. 3.5 ft by 6.5 ft. and spaced apart by about a foot. they are held by 4 anchor bolts and 4-L brackets. the brackets were screwed into the ceiling 1st. then the panels were held up by TWO PEOPLE ON TWO LADDERS, and then screwed through the descending piece of the L-bracket into the edges of the panels once
they were measured to be parallel to one another. the panels don't weigh much at all. but you have to clear the space underneath- a pain in the "neck". falling popcorn will get all over the stereo unless it is completely covered. in my case the ceiling is really high, so
the TWO INSTALLERS must be comfortable working on two 8 foot ladders, and have to take PRECISE MEASUREMENTS.
as for the sonic results, they were well worth the effort- slap echo was significantly reduced. plus i acheived the "concert hall acoustic ceiling" appearance that i was hoping for. as i recall, the four custom-made panels cost about $1200 shipped, and they included the hardware too. my "theory" that adding sound-absorbing surfaces to the room REGARDLESS of the precise location would STILL be helpful, and luckily it worked. my walls already had framed-art that i really loved, so i was determined to leave them in place. anyhow, the room looks nice and sounds nice. YMMV of course.

Thanks for all responses. I will most likely give it a go.

French_fries, may I know if your Echobuster panels are purely absorption, or a mix of absorption and diffusion?

Thanks in advance.

I found that RotoFast connector/mounts made all mountings quick and secure, even on the ceiling.

Interesting post Frenchfries.I commend your ambition and attention to detail.Glad to hear it was a success.Thats the right way to do the job.I set-up a Bakers scaffold which helped immeasureably[sp],but I am glad if I dont have to work on the ceiling again though some rooms require it for optimum sound,cheers,Bob
