Listening chair suck-out


Oh brother. I've been placing acoustic panels here and there in my room in order to deal with various reflection-based frequency anomolies, with remarkable success for the most pary. I use an SPL propped up with a tripod to the listening position, which happens to be in a comfy stuffed leather chair The chair eats 165Hz! About 25dB of it, to boot (from about 75dB down to 50dB). If I put the mic at the listening position sans chair, there is no suck-out at all. It is definitely the chair. Anyone have tips for building a marble throne?

How about a porcelain throne instead or marble. I think home depot has a sale on them so since you wont be flushing who cares about the flushing strength!!! :)
I had the same problem with a high-backed leather chair so I opted for a low-back chair with excellent results. To get clarity in the higher chair I needed to sit up straight to get my ears above the chair back. No more muddled sound and I don't feel any less comfortable.
The bummer is my wife bought me that chair expressly for my room.
Forgot to mention get a good comfy seat and seal it shut so no one mistakes it for something else.
Definitely look for a chair that does not extend higher than your shoulders. Your head should not have anything immediately behind it, otherwise you will hear that suckout.

Enjoy,
