my room responses

Hello everyone, I have attached pictures of my room responses, included 2 waterfall graphs. There is no eq except for a Marchand Bassis which boosts and adjusts Q of my sealed diy subs, set at 38hz. The room is extensively treated with broadband and two types of panel traps a la Ethan Weiner Real Traps diy plans. There are currently 25 2'X8' traps and 15 2'X4' traps. I will be adding another 18 2'X8' traps at some point.
REW and bass trapping have been the most enlightening/revelation in my audio life. Thank you very much!!!!! I have been able to adjust my sub setting and main/subs positioning which was previously impossible to do before by ears alone. Also to be able to put a "face" to the sound is a revelation and makes it possible to really understand your system and rooms acoustics which was only "theory" before. Now I know what I am hearing. And loving it!

Thanks again,
Bob

Re: my room responses

Oops again, and now down to 20hz! Also note the measurement is 74.2db not 75db because I have stepped attenuators and this is as close as I can come to 75db.

Re: my room responses

Responses look very good. If you have the space then extensive treatment can reap big rewards, though with 40 already in place and 18 more to come is there room to squeeze in past all the traps? You could be a record holder on the treatment front.

Re: my room responses

Hi, my room is 16'X23' with a 13' ceiling at the peak. Then there is a loft area to my left with another 13' ceiling at the peak. This is in an circa 1850s converted barn, which is for my motorcycle collection and listening room. At this point most of the bass traps are in the front half of the room. The next 18 traps will be on the ceiling in the rear half of the room. There are 12 on the front half of the rooms ceiling. There is plenty of room without feeling claustrophobic. The first two pictures show the rear half of the room and third picture shows some of the free standing traps as well as some ot the traps on the ceiling.
The main speakers are Acoustat six, with DIY subs using eight froward and eight rear firing 8" eminent tech driveres in a sealed cabinet in a stereo pair for a total of 32 drivers. Crossed over currently at 120hz.

Re: my room responses

Hello, And the number one reason for bass traps is...my DIY subs, a picture of them under construction, an in room picture and my early attempt at room treatment. And dont forget there are just as many drivers in the rear of the speaker. In the last picture you see my early attemps at "room treatment", its really laughable that i was told to use blankets...foam etc.. well it would be laughable if it werent for the fact that I wasted time even thinking this would help. And unfortunatly people are still being told to do this, by people who should know better. Plastic ficus trees anyone?
