John Sayers' Recording Studio Design Forum Archive

I am totally new here and had NO idea this forum existed. I'm SO happy it does!! I hope you all can give me some help here.

I need help in reading the results from REQ Wizard and what I can do to tune my room properly. I have badly needed to get this done and had a serious brain fart about how to get REQ to work (it's not exactly intuitive). So I found a Youtube video of somebody going through the setup that helped me considerably. The following photo is what I got from my first measurement.



It looks as If I have a big DIP in 65hZ? What can I do to help smooth this out? I have been told that perhaps an EQ on my master bus (disabled before exporting) to make adjustments - OR a hardware EQ in between my soundcard and monitors might do the trick.

BACKGROUND:

My room measurements are

WIDTH: 9 feet
LENGTH: 11 feet
HEIGHT: 7.5 feet

(I did the calculator at http://www.bobgolds.com/Mode/RoomModes.htm and attached the PDF)

Forgive this extremely naive and NOOB-esque thread, but I am probably not the only one with this problem and I hope to help others overcome.

I was told that Hemholtz Resonators might be my solution in a small room such as this, and even perhaps membrane resonators. It will be a DIY project, so I may need someone to turn me on to the procedure for obtaining a formula and/or plans for building a resonator.

HERE ARE SOME CONTROL ROOM PICTURES

NOTE: I now have bass chunks (AURALEX) in the front corners at speaker level

it's likely the floor - ceiling mode causing the dip - consider replacing the overhead cloud with a heavy hard back cloud with an absorptive front. hung on an angle and down from the ceiling. this will help shift the mode. make the panel wide and deep enough to cover most of the area over the front and mix desk - leave about a 12" gap or so around the edges. angle front (low) to back (high) around 15° or 22.5° if possible. use 3/4" MDF and 3/4" plywood with the cloth absorber on the front (bottom) of it.

Ok interesting, so when you say CLOTH ABSORBER on the front, what thickness and what if anything would go between the cloth and the plywood?

4" thick 3lb/ft3 rigid insulation covered with fire retardant treated cloth - make it out to within 6" of the edges of the panel.

Hello, this is what I have over my desk already. It is 4" thick and full of 703. Should I just try repositioning?

id say yes. also, You have you speakers close to a boundry ( front wall).

try moving things a bit to see if it changes before you adding more absorption.....

Will do. I have experimented with my crossover settings and this has made a HUGE difference as well.

It's strange that those speakers were made to be mounted like that. The wall mounts are specifically made for those speakers, so I guess the manufacturer is cool with it and apparently they are supposed to work well like that!? Their rear-ported too. It's the only place I can really put them; the room isn't the biggest.

I'm going to experiment with moving my sub around and I hear talk of adding another sub in a different area is a good idea too.

Thanks for your help!
