simo, 17 September 2010Hi Carsten, Thank you for your very quick reply and the tip to insert text between pics! It so great to feel that you are not entirely on your own! Cheers I'll give it a…
simo, 17 September 2010oh this is fun ! I'm on a roll now :-) here we are with some more: - some more material arrives (with my dear dog guarding it) S44.jpg - walls bricklaying begins S45.jpg…

simo, 17 October 2010Hey Glenn, Thank you very much for your expertise - much appreciated! So, I think that I will have to live with that then (as I'm playing with a limited space). I will…
simo, 18 October 2010Dear all, I'm really worried now.... I've been enquiring about HVAC systems for my studio.... and the result is quite simply astonishing. The first quote I received was…
xSpace, 18 October 2010If I had to guess, the biggest issue is that you got the HVAC guys involved at the end of the build and they should have been part of the design phase. The costs are…
gullfo, 18 October 2010if you go with the split units and an air exchanger per room (like an AeroPac) the cost of the systems should be reasonable but the installation and so on may be the…
simo, 21 October 2010Hi Brien and Glenn - Thanks for your response and suggestions. Much appreciated! Actually though Glenn... I'm not even near the end of the build . . . as a matter of…

simo, 27 October 2010Many Thanks for your kind words Glenn and Brien ! Brien - I know you weren't suggesting to scrap my previous ceiling design in favor of the method used by John in his…

simo, 4 February 2011Hi Brien, Thanks a lot for your quick reply ! Actually, when I got it I just finished to trim the last stud, as I thought that 5cm shorter won't kill me but (apart from…
simo, 5 February 2011Hi Brien, yep - now the wall is 5cm shorter in order to match the sheet rock dimensions (and in order to gain a little extra space for the HVAC ducting). I thought that…
simo, 5 February 2011Hi All, ...ok, another issue ! I purchased rubber strips (15mm thick) to install under the bottom plate of my walls, mostly to compensate for variations in level of my…
simo, 5 February 2011Thanks for your reply Glenn, yes, as you said, it was just to hold it in place while moving the wall in position. Being the wall very heavy, I thought it would be easier…

Soundman2020, 20 March 2011For what purpose? Just for sealing? Or for decoupling? You can only decouple a wall with neoprene underneath it if you also use some form of isolation on the bolts that…
simo, 20 March 2011Hi Stuart, Thanks for your response and advise ! The reason why I put rubber strips under the walls is because the concrete floor is quite uneven in certain areas, so it…

Soundman2020, 23 March 2012John does NOT recommend plywood for the cores: he recommends a very low density, soft fiber board, called "Homosote", which is made from recycled paper: It's the type of…
simo, 23 March 2012Thanks for your quick response Stuart, always informative and detailed. Strangely I can't find anywhere the Homosote in this part of the world, or any equivalent…
BriHar, 26 March 2012I've seen everything recommended as a core from cardboard to plasterboard, plywood being a very popular choice. Many studio designers have their own personal choice.…

simo, 31 March 2012Thanks Stuart for your response ! I managed to find a supplier for Sorbothane here in the UK… wow! that stuff IS expensive: 500x500 x 3mm (£39) 500x500 x 4mm (£46)…
Soundman2020, 1 April 2012Yeah, but it's the best stuff for isolating speakers. Neoprene and EDPM are the next best, I think. Some types of foam will work too, but the key is to make sure that…

BriHar, 4 April 2012The House Service panel should already be earthed with a rod - you should not need to drive another extra rod (in fact you might find this is prohibited in your local…
simo, 4 April 2012Thanks so much for your help Brian , much appreciated !! Yes the House Service panel is earthed with a rod in the ground under the floor boards. Ok, I'll scrap the idea…
BriHar, 5 April 2012I'm not sure what's planned here. It looks like your Electrician is branching 3 phases to the out-building (or is it 2 phases and neutral?)- I had assumed a sub panel…

Soundman2020, 25 April 2012Yup! That will work just fine. Exactly. Normally there are two pipes and one electrical cable. Exactly. You'll need two silencers per room, one on the incoming fresh air…
simo, 4 May 2012Hiya ! Here is a sketch of how I was thinking of doing the fresh air in / stale air out system - hope you can follow it. I made it just for the control room, but…

simo, 10 May 2012Right.. bad news …the budget is drained ! :( As it stands now I won't be able to do the air con at this moment . If i did, I'd be left with just stud walls and a…

Soundman2020, 14 May 2012One option that comes to mind, is to do one single stud bay "conventionally" instead of "inside-out". In other words, the two studs right next to where the A/C unit will…
simo, 15 May 2012Great idea Stuart !! and fitting that "conventional" section into the rest of the build shouldn't be too difficult… I think it's just a matter of having one additional…
Soundman2020, 15 May 2012That's what you're paying me so much for! :) You could do that, but you don't really need to, unless you were planning on more than two layers of drywall for your room.…

simo, 29 July 2012Thanks Stuart, yes I think I'll go with option A… easier to build, adjust, remove (if needed). I read somewhere that a 18mm plywood layer and a 18mm MDF layer screwed…
Soundman2020, 2 August 2012I don't think it needs to be that massive. The density of plywood and MDF are pretty similar, while MDF is slightly more dense, so that "wisdom" you read seems to be a…
RJHollins, 2 August 2012Just to mention ... 'Gullfo' did the design for my hard backed clouds, and recommended the combination of MDF and plywood. It worked out very nicely, as the MDF provided…

Soundman2020, 2 November 2012None of the above! :) You seem to be confusing a bass trap with a speaker soffit. The front face of your entire bass trap should just be cloth, nothing else. The purpose…

Ro, 14 June 2013Wouldn't worry too much about interference on your speaker cables. It's much higher power than your average audio/mic signal. Either add long balanced cables (xlr) from…
simo, 14 June 2013Wow!... what a blessing all this help - thank you so much guys !! Ok, I had a chat with the technical engineer at the studio where I work, to get an additional point of…

simo, 6 October 2013Thanks for the reply John !! I did screw the box down to the plane it's resting, see here: Image not preserved: IMG_2784 edit.jpg for the very same reason you are…
simo, 6 October 2013Ok, I will follow your and Stuart's advice to remove the extra sorbothane around the box ( NOT the one that is lying on the inside, between the box and the speaker !?).…
Soundman2020, 6 October 2013One thing you could do first, Simo, is to do a REW test of the room, and see if there are any signs of resonance in unexpected places on the graphs. If REW can't see…
Ro, 7 October 2013Hai Simo, I just browsed through your latest updates and I too am impressed with your craftsmanship. Cheers on that, mate! Now, about your resonance problem. Dealing…

Soundman2020, 8 October 2013OK, yes, but that is THICKNESS they are talking about: You also need to know how much AREA is right for the load you are putting on it. Think of it like this: If it…

simo, 2 February 2014Thanks for your answer Stuart . I think I settled for a 50' roll of 1/8" x 3/4" (3.2mm x 19mm) neoprene setting block. The other option I found is 3/16" (5mm) setting…

Soundman2020, 10 February 2014No problem, Simo. That's the normal way of doing it. Fit a piece of Homasote across the gap between the windows, cut a groove in it, put the silica gel in the groove,…
simo, 10 February 2014Thanks for you response Stuart , as clear and detailed as usual, like reading a step by step manual. :thu: Is there a limit to your knowledge?? :D :wink: Wow, homasote…
Soundman2020, 10 February 2014Ooops! I forgot to mention that you DON'T nail it in place! Just "pressure fit" in place: cut the Homasote to just the right size, so that when it is wrapped in fabric…
