From the photo of the laptop screen I would say it is the AFMG Easera

4982 I'll delve back in to the John Sayers forum and find his stuff on slat absorbers. It is a little tricky to find te page in that forum, so I saved it! http://www.johnlsayers.com/HR/index1.htm One thing I noticed is that due to the imperfect nature of the wood slats the gaps between them are not...

Thanks Gareth, What I was trying to achieve with the slatted wings was to eliminate the flutter echo from the parallel walls, minimise the low-mid colouration bare surfaces or insulation panels (other potential treatment) may have and keep some brightness/harmonics in the room for any recording may ...

Thanks Stuart!
Will try it asap!

Thanks Jennifer ! the house curve I used is not an "ideal" one, it's just the EBU house curve (attached) and I used it as a starting point. I would say that it sounds a little "generous" at the very low end (<80hz) but since my last experience in a reference control room was many...

Thank you!!

But this 40hz resonance was still there strong and proud, so I made the decision to revisit the MLV absorbers. I drilled two “pressure equalisation holes” (one each) sealed them and re-sealed some parts that the caulk seemed to have cracked. And then I took some measurements. And after a few eq refi...

Since I have sort of finished the room, it has been time to eq the speakers. I have a Void Acoustics Digidrive+ and a tri-amped setup, so a lot of flexibility. After a couple of tries and a ton of eqing I came to this state, with is a big improvement to the previous one. Dio Ministudio EQ v3 wtrl.jp...

Hello, I realised that I left this thread with no updates for some time, so here is one! After making the diaphragmatic absorber (with its not so good performance…) between the speakers, it was the time to finish the plan I had (see post #15) with the angled side slot resonators (wings). The idea wa...

There is a plastic mesh holding the insulation in place (shown in picture in post #44) and a very small gap so that there mlv can vibrate freely. The insulation is on the mlv side, not on the wall.

Hi Eric and sorry for the late response. While I was toying with the acoustic modelling simulator I noticed that if you have about 25cm of empty space, a 5kg/m2 membrane and some insulation then you can target 42-43hz. The space i had between my soffits was 23cm deep, 5kg/m2 MLV is easy to find, I h...

Thank you for the analysis Stuart, the anomalies on the speakers response is something I do have noticed but wait for the room to be in a good acoustic shape to address them. These speakers are custom made and an old design (and probably a weak link)I already had before I start this studio construct...

Hello Stuart, Thank you for your detailed clarification. Regarding the images I begun with some settings in REW (I don’t remember the reason why ..) and for reference with the older posts I kept them. Now that the room almost finishes I think I will switch to the defaults. Here is the mdat: dio Mini...

After a long time back here to continue that small project. What I had was a small cavity between the soffits, ideal to build some limp mass absorbers, why not?

Hi Gareth,
I ‘m quite busy these days as our “beloved” government rapidly opens everything up. I do have something to share, hold on a bit…
Cheers
