So here they are. I hope the mounting is depicted intuitively enough. After a few days time with them up, the imperfections are bothering me less. We'll see in time what the verdict is.

Those look awesome, John. Have you noticed much with the sound by ear yet? I'm assuming you plan to update your 'binder' at each step? I am excited to see it.

Hey Neil, thanks.

They are not all up yet. Observations to this point: after installing 5 around the drum corner, in a practical sense the snare has a lot more snap... attack. The cymbals for sure are brighter. Whether or not it's gone too far I'm yet to decide. It may be a bit harsh but the difference is so jarring at this point; I need some time with it and ideally a track and mix is coming within a month or so.

Experiencing them with less than drum SPLs, standing and talking in this corner is far less oppressive feeling.


There are still 5 more of these that can be installed in the rest of the room. I'm holding off to decide whether or not they offend me visually. I may end up painting them a satin grey to give less contrast on the holes. I may end up covering them with a very thin fabric. Either way, my room is so cluttered with control room gear and multiple drum sets, that finishing and measuring at this point would be so skewed due to gear that it will have to wait.

JohnD.....

It wasen't my intention at all to get you upset with my comments. I feel sorry if I have. I have the upmost respect for your craftmanship and I have never critisized you for that. I know how hard it is to build something acoustically, a hell of a jobb.

I only gave comments of the measurements.


Thanks

water under the bridge McTwins. I'm not as bothered as perhaps my reply suggests.

First session with the bad panels.

Also happens to be my first session with my 7th Circle pres, and I also borrowed some new mics. So..........

Far and away my best drum tracking session.

Is it the panels? Is it the pres? Is it the mics? Is it more experience?

I think there's a natural progression with all engineers that makes specific improvements impossible to nail down as the reason of greater success.

Most dramatic improvements:

Snare drum. Far and away. Crazy nice transient with the the condenser. SM57 pushing the limits of the API-esque 7thO sounds exactly like I want a snare to sound. There's a considerable difference with the room's sonic outside of the recording chain, so I'm confident in saying the BAD panels are a huge factor here.

Overheads. Cymbals sound less choked.


Track count:

1. Kick- Beta 52>N72
2. Kick- Homemade subkick>Ghost
3. Snare top- SM57>A12
4 Snare top- SM81>Ghost
5. Snare bottom- SM57>Ghost
6. Rack- MD421>Ghost
7. Flr1 top- MD421>Ghost
8. Flr1 BTM- ATM450>MPA Gold
9. Flr2 top - MD421>Ghost
10. Flr2 BTM- ATM450>MPA Gold
11. Overhead Rack - C42>C84
12. Overhead Floor - C42>C84
13. HiHat - AT4081>Ghost
14. Ride spot mic - KSM141>Ghost
15. Drummer's ear -AT4060>N72

After I get the tracks leveled out, I'll post a clip of the premix drums.

I want to face all of my broadband panels with a binary amplitude grating. Plenty of 1/8" ply left. I figure I can stack them all and drill at once. Deciding if I want to modify a plunge router to hold my drill, or if I should go the drill press route. That would mean buying/renting. Also not sure if a drill press would have the clearance to get into the middle part of the panels. Either way, I think I will have to incorporate a sled/jig to ensure straight lines.

As rendered, the panels are same top and bottom. Even drawing 1/4 of a panel and copy/flipping was tedious. When carried out, I would use the negative for the bottom half, and then I can simply turn ever other trap upside down to avoid repetition.

My reasoning, is that I would like yet a bit more 'life' restored to the room. The polys are great, but the room's decay still feels dry to me.

Awesome idea

AMEN!
