I’m curious to see how you guys approached front wall treatment in your spaces. I’ve seen some control rooms with a lot of absorption, some with diffusion, and some bare. Did you focus on the corners, other walls, and ceiling instead?
I’m using JBL LSR305 speakers at home. I moved the speakers closer to the wall from 12” to 4” and it evened out nulls in the 100-140Hz range. There is a block wall 6” behind the front drywall, so I suppose the block wall is the the actual surface reflecting all of the low frequencies.
I was originally going to make two panels to put behind the speakers when they were 12” off the wall. However, placing a 4” 703 panel directly behind the speakers did not seem to help in that 100Hz range.

I just put a few 4" thick panels on the front wall. Mainly behind the speakers. I did it mainly for reflections, not balancing out the room modes.

My favorite sounding control rooms typically have a lot of broadband absorption in the front wall, and/or soffited speakers

A couple thousand LPs has always worked for me!

I think I’ll add some more absorption on the front wall sooner rather than later. I’ve put up some absorption around my room, but my front wall is pretty bare for now.  |

Oh yes, part of the junk pile! There's also a 1995 Powermac 8100 behind the Palindrometer and it sits atop a 1992 Panasonic DAT machine (one of 3 defunct ones) |

Only proving that those old macs last forever, including their second life repurposing.

This seems appropriate... 20 odd minute video showing BOP studios in various stages of construction. Tom Hidley room. Everything is exposed here including the massively deep bass trapping. Hidden behind / built into walls. And an old SOS piece on the studio w/ some pictures & from the hip floor plans etc. www.soundonsound.com/music-business/bop-studios-storyGood stuff! |

Front wall treatment has as much to do with the choice of monitors as anything. Personal generic preference if there isn’t a giant window or video monitor is a combination of broadband and a bit of diffusion in the middle. Treatment is one of the reasons for years video projectors were popular for years.

I bought a few pieces of Owens Corning pipe insulation to use as tube traps, while my hands are sidelined. I'm going to put some fluffy insulation inside before I cap them.
I went with 10" pipe (1.5" thick, ~14" OD) and 6" pipe (2" thick, 10.75" OD) sections. I'll eventually build some more flat panels anyway, but wanted to experiment with tube traps in an AttackWall type configuration.
A few days ago, I had placed a 4" OC703 panel next to my speakers, and did a quick measurement. It didn't change the frequency response much, but it did lower the decay time in the 200-300Hz range down to the 200ms.

View AttachmentWard, I'm totally digging the stone in your live room. Do you find that it not only looks great, but the surface variations of the stone help with diffusion? My previous studio had an 11-ft tall wall covered in slate. I loved that; both for visuals and sound. Thanks for posting the pics. -09 |

It's really awesome! I got to experience it at The Tracking Room in Nashville back in '18 and then decided I had to have it. It's beautiful!! Breaks up and bounces stuff around all over the place like a diffusor does too.
Love the sound of having one stone surface.

I ended up making some tube traps of pipe insulation and fluffy fiberglass with a bit of free time. I put 2 tubes to the sides of each speaker, and 1 smaller tube directly above.  What seemed to help a lot was putting a 14”x18” tube directly above the speaker. It seems to start working at around the 140Hz region, which is what I was hoping to clean up. Below are left and right speaker measurements from Room EQ Wizard, 30Hz to 300Hz with no smoothing. These are measurements with and without a tube trap above the speaker only. I already had the side tubes placed.   The sound might be a bit tighter from preliminary listening. They are fairly modest changes, but I think it’s a net positive result in the end. |

Makes sense, Remember that wave guide controls dispersion in 3D. If you want to cry about how much you wish you had loads of space pull everything away from the desk and put a tube trap in front of the speaker with the top at desk height, sadly I have done such. It gave us the audio Yoggie Beara quote “ this console could only sound better if there wasn’t a console.” |
