Is this setup okay? I've already read Ethan's "How to setup a room"

[analog orange]

I'm in the process of building traps and at this point am trying to determine placement. I building at least 4 if not 6 6" bass traps and placing them in corners. The sides (of the traps) will be completely open for max absorption. From there I plan on making 10-15 2x4 broadband absorbers out of 3 or 4 inch rock wool. Do you think the difference between 3 and 4 inch will be appreciable or can I just stick with 3 inch?

Some important info before I get to the major question. I've got my room set up in such a way as to pretend it's 14x13 when its really kind of 14x20 because of the 7x9 alcove on the left. (see the picture)

As a side note, the floor is wood, and the room has walls that on the longest side angle up to the 8.5' ceiling starting at 4 feet. And on the opposite wall starting at 6 feet. So the room is irregular as hell.

So.....

Should I turn my mix position 90 degrees to the right? When I originally set up my room, the thinking was that the back (12-13ft) wall would reflect back equally. Whereas if the alcove was the back of my room, then the sound would reflect early on the right side and freak out my stereo image more.

Thoughts? I'm willing to move it, I just want to know what's right before i do.

FWIW, while my daytime mix room for the last 7 years has been a Russ Berger suite (I am blessed), the mixes made in my little room at home have translated amazingly well when shuttled between the two. The room in question just has no low end definition. It is mush from 3-400hz down.

Thanks in advance. You guys are the best.

Yes!

Not only because it's the longer dimension and puts the rear wall farther back behind you, but also because that gives you two different wall distances. And that reduces peaks and nulls a lot.

So I should center myself in the 14' space about 7.5' from the 10' wall, correct?

How many broadband absorbers do you think I should put up? I'm building them myself. I was thinking 4-6 bass traps and 10-15 broadbands. To many, too little?

And thank you BTW

go with the 4". Sounds like you are making some major improvements, which is GREAT. Go with the thickest you can.

More bass traps, fewer broadbands, though I'm not sure exactly how you are differentiating them. For the bass traps, they should be 4" thick. For the broadbands, I assume you mean thinner panels to be used to create your RFZ. For a small space, 3 might be enough. On the other hand, you want bass traps in as many corners as possible, as well as the rear wall, and possibly the front wall behind the speakers.

Your head should be 38% of the distance into the room. If the length is 14' that would put your head at 5'4" into the room. If the length is 20' that would place your head 7'8" into the room.

More bass traps. You could do 12 in that room without a problem. You'll definitely want to deal with high end reflections, especially at around the listening position, but it's secondary to getting the low end under control.

Thanks for all the help guys. I moved the desk last night and it definitely sounds different. Clearer but askew. I'm sure the room treatments will compensate for this once they're up. I'll post pics when I'm done. Here's a drawing of the new setup and placement. Please comment if you see something off.

It looks like after 7 years I may be losing my Berger mixing room in December, so my place at home needs to sound badass. Thanks again for all of your expertise. You've been a great help.
