  • garethmetcalf, 19 February 2017Hi I have another thread where I've been exploring a design for a studio in my garden built from the ground up. As I've been designing I've been watching the costs mount…
  • Soundman2020, 20 February 2017Rather long and thin.... and square! Strange! Why would somebody glue plaster board to masonry? Why not just plaster the wall directly? IT might be an idea to deal with…
  • garethmetcalf, 21 February 2017Hi Thanks for your replies Stuart. This seems to be quite standard practice in modern homes in the UK, called Dot n Dab: https://www.google.co.uk/webhp?sourceid ...…
  • Soundman2020, 21 February 2017It's actually not hard to do.... if you build the ceiling as a "backbone" of larger joists, more widely spaced, and put individual "modules" in the gaps... build the…
  • garethmetcalf, 21 February 2017Thanks Stuart. All points about isolation and dimensions noted and I had of course seen the 'fail' notes on the Bob Golds calculator. I think the conclusion drawn from…
  • garethmetcalf, 30 May 2017After even more research, planning, talking to builders, calculating and not to mention talking to my wife I have a revised plan that I've made a start on. The garden…
  • garethmetcalf, 26 June 2017Hi I've spent more time working on my sketchup model and have got a working design to go forward with. Due to the long thin dimensions of the room combined with wanting…
  • Soundman2020, 27 June 2017Just a few random comments: Is that legal? Are you allowed to cover your electrical panel in the UK? :) Maybe because you aren't wearing gloves? :) Sadly, the spider…
  • garethmetcalf, 27 June 2017Thanks Stuart. I'm not sure that our regulations do allow consumer units to be concealed, but they are allowed to be in cupboards, for example, hence why I will be…
  • Soundman2020, 27 June 2017Smart move! As long as he says it's OK, then you are fine. That's fine for cooling flow, provided that you also allow the 3" depth at the back, as recommended by Mackie,…
  • garethmetcalf, 28 June 2017Thanks Stuart for a very helpful reply. I've made a sketchup file with a design for a speaker box following your suggestion of 130mm behind the speaker including air gap…
  • Soundman2020, 28 June 2017Much better! :thu: Very much necessary! It gives rigidity to the box. It's the only thing keeping the sides, bottom and top mutually parallel and square. So it's not…
  • garethmetcalf, 29 June 2017Thanks again. I've followed your advice - the speakers are away from the corner (a bit!), and slightly further into the room. The axes intersect 30cm behind the head.…
  • garethmetcalf, 20 July 2017So it's been a few weeks and I've been busy every spare evening I have, around day job and function band commitments. Thank god I've no studio work on at the moment...…
  • garethmetcalf, 20 July 2017Continued from previous post... We then built a new outside wall, installed my ventilation system with heat recovery unit, and the new UPVC normal width glazed door.…
  • Soundman2020, 21 July 2017Wow! It's starting to look like a studio! Good work there, Gareth. And I'm glad you passed your inspection! :thu: :yahoo: That's really good news! Now I'm just wondering…
  • garethmetcalf, 21 July 2017Hi Stuart You're right about the old door. It's no wonder I could hear any car that drove past! Anyway, because I need to get this job finished sooner rather than later…
  • garethmetcalf, 24 July 2017It's amazing how long this stuff takes to build!! This is about 2.5 day's work... half finished framing. Hope to get the speaker boxes built, shelves beefed up, framing…
  • garethmetcalf, 24 July 2017Another slow day.. Made speakers boxes and then did a load of work to the left soffit including installing the 5 hangers. I'm awaiting my electrician before I can do…
  • garethmetcalf, 26 July 2017So today I've almost completed the left soffit. I think I remembered everything I need to do! The rear of the speaker box has 2" insulation in it, covered with chicken…
  • Soundman2020, 27 July 2017You'll probably have to "test and adjust" to get it right, using REW, but for the first approximation I'd suggest 37 Hz, "B" and flat for the highs. Yes, I know you have…
  • garethmetcalf, 30 July 2017So both soffits mounted, speakers installed and first REW tests taken, using the speaking switch settings suggested by Stuart above. I remembered once I'd done the…
  • garethmetcalf, 2 August 2017So tonight I finished the ceiling/wall intersection absorbers, and put some covers on the front of one of the soffits, top and bottom. I re-ran REW and weirdly some of…
  • Soundman2020, 3 August 2017Those are probably SBIR artifacts, not modal. To confirm, we can do the "walking mic" test, which is a long and boring process, but reveals a lot about the room... and…
  • garethmetcalf, 3 August 2017Thanks for your helpful advice, Stuart. I will do the string test later, and the walking test once I've put this round of treatment in. Mains hum: that's either because…

  • Soundman2020, 3 August 2017Better to do those NOW, before putting in the treatment! How will you know what to treat, if you don't first do the tests? :) Also, treatment will "dilute" the…
  • garethmetcalf, 3 August 2017Thanks again Stuart, and I'll reply to your PM shortly. I took your advice and did the walking mic test before adding any more treatment. Results for that are:…
  • Soundman2020, 4 August 2017... or maybe with your interpretation of the data? :) Here's a small part of the results of your walking-mic test, which clearly shows what the real problem is at 136…
  • garethmetcalf, 5 August 2017Ah OK this is vey helpful and insightful. I'll try dropping some treatment on the floor as you suggest to confirm it is a floor bounce. So, if that is related to the…
  • garethmetcalf, 8 August 2017Work still continues... I have installed the remaining bits of treatment: a panel of 2" insulation either side of the corridor, and a small super chunk between the…
  • garethmetcalf, 10 September 2017Here is a long overdue update. I've been busy using the room because it feels, and most importantly, sounds great! I've recorded acoustic guitar, electric guitar and…
  • garethmetcalf, 13 December 2017Thanks Jeremy. I've realised I didn't add my final graphs. I've not added any plastic to the traps as I feel the high end is good as it is. I've just got the first…
  • garethmetcalf, 17 June 2018That’s fantastic Stuart!! Thank you so much. I’m still loving using the room - mixes translate brilliantly, imaging is awesome and it works great for tracking guitar and…
