The room looks great.

I'm surprised you went with an install rack.  I figured you'd be ready to be mobile at a moment?s notice.

Tell us about the speaker stands please.

I'm gonna have to take a trip down while I can still have the top down...

i'm tired of moving those racks around, they don't look good in a fixed install, and i don't even have a vehicle to move them......if i REALLY need a piece of gear for a track session i can just pull it and take it with me.

speaker stands.

the base is microlam (material used for headers in new home construction)

polls are 1.5" galvanized steel pipe attached with 1.5" galvanized flanges. i had them cut and threaded at home depot.  

the top plate is two pieces of 1"x12" pine glued and screwed together.  i then used a planer to make a 45 degree angle on all edges just to give it a nice finished look.

half a cinder block for base weighting (should have spray painted them.)

then i set the base spikes using a drill press, screw in the threaded inserts, screw in the spikes......

i then cut 3" square pieces of masonite to keep the spikes from digging into my carpet

i also used those "shims" to level the stands as my floor is uneven.  i got the spikes at:

Can we get a couple nice pics of the rack?

[j.hall]

sure, but it's nothing to write home about.

just random gear i've collected over the past 7 years.

New Mix Room .... New Pro Tools ..... New mac .... no car!

I think this must be the deinition for an indie rock engineer.  heh heh!

No ride? Where are you going to check your mixes?

Seriously, the room looks great and must sound even better (I'm taking your word for it.)

Are you completely operational at this point?

[j.hall]

ha

i just sent you an email......literally, i just sent it, and came here, saw your post and laughed

you must be off tour now....

i have a car, just not one big enough to carry around two road cases and other things i used to cart all over the place.

had to always rent a van or something.

the room is about 5% from being totally installed

it sounds incredible.....

J. the room does look good!  Well done.  I would be interested to see frequency response, rt60 and such of the room.  Im guessing it is pretty flat since it seems to sound so good.  Ive really enjoyed reading this thread.  I hope brad will do the same for his new build out!

thanks

probably won't do a transfer function or RT60 unless i feel like my mixes aren't transfering well.

you'll have to take my word for it, or fly down here with some CD's you know well

jealousy.  that'd pretty much sum up my feelings.

It's looks great, and I know it sounds even better.

This thread has been informative and interesting...


cheers!

A quick question..: It seems from the pictures that your mix position is not quite in the center of the room...Did you have to take this into consideration when you were doing the acoustical treatment, or does it not matter? I guess if it sounds awesome, it must not matter...

Maybe I'm being fooled by the photos...

Anyway, this whole thread / project of yours is really reassuring to those of us working in small rooms...It can be done!!!

B-rad set the mix position

from he siad, it's a two-thirds to one-thirds ration

i'm 5 feet off the front wall centered between the two side walls

the space is about 15 feet deep.


if i move 12" back from the mix position the image goes to garbage.

from some very rough measurements......some where around 200Hz, is 2.5db down at the mix position.....

12" back, it's 7 db down

the rear of the room seems pretty accurate as well.

most places in between are not very desireable.

[craig boychuk]

Cool, thanks for the info, J. I know what you mean about tight mix position...I recently moved my position back a foot after finding that my stuff was translating with too much bass. Made all the difference in the world! How did you do the analysis to find out problem freqs...did you use an analyzer or just figure out the modes on paper?

[j.hall]

i listened to MANY CD's that i love and have used for years as ref material

once i realized that i had never really heard these discs i started grabbing all sorts of stuff.

i NEVER listened to any of my work while setting up the room.

i got the speakers rough placed by just listening to program material

then i ran sweeps and listened to see if anything in the lows popped out.

i got the mix position set and did the final speaker placement based on that.

after that i grabbed my SPL meter (C weighted slow) and wathced the meter go as the sweep went from 20 to 20k.

i could hear the low mid dip 12" back

i first thought the low end was much bigger back there, but realized that it was the same, the low mids just got sucked out.

at the mix position i couldn't really hear it that well.

the meter was showing about 2.5 db of dip.

i have no idea what frequencies the dip is at.  i just know by ear it's in the low mids...i'm guessing between 150 and 250.

from there the response was really smooth, as i had been hearing for a week or so.

took me awhile....but as requested
