That said, when I was growing up, my parents had a handyman who used construction adhesive and nails (he hardly ever used screws; guess that's why his prices were so good!) for EVERY project. Fortunately, he never did any framing, or who knows how it would have turned out. Interesting, it was my un...

Also, here are some more framing tips for those of you who are inexperienced builders like me and want to avoid wasting time: 1.) ATTACHING TO HOLLOW WALLS If you need to attach something to a hollow wall you should locate the studs already inside the wall (I knocked the wall & listened for chan...

So I went with 40 duro in the end as I wanted a good compromise between high % isolation and isolator stability (e.g. if I went for 70 duro the % isolation would be v good but the isolators would be v thin & unstable, causing the speaker to shift over time. If I had really heavy speakers then I ...

Here are a couple useful quotes from Stuart on using breathable plastic for your traps: Plastic is a good way of retaining any loose fibers, yes, and thin plastic on the cloud above your head is a very good idea. Will it have an effect on acoustics? Absolutely! Yes! And that's a good thing, because ...

Dude I completely forgot that there's an entire section of this forum for construction threads! You hadn't updated your design thread in a while so I thought you'd frozen or even abandoned your build or were just building in secret :lol: I'm legit floored at how much work you've done in so little ti...

So after many a cock-up, I finally finished my soffit framing. Phew! I actually thought I'd finished a few weeks ago but to my horror I noticed that the horizontal studs weren't parallel to the plywood platforms (which are cut at the correct angle), so I knew I'd messed up the angle somehow. I reali...

Welcome to the forum MaseyRoy! I already answered that Q on the first page of this thread: So I used amray (https://amcoustics.com/tools/amray) for a general view of all the 1st reflections (the pics w/ all the blue lines - very rough as you have to trace lines over a top-down 2d export of your desi...

I think the design for sorbothane hemispheres where they can be compressed by tightening a threaded bar is part of Stuart's design for soffit mounting - I'm sure I've seen it in a picture of old. I've decided just to set the gap between speaker and box the right size to allow the hemispheres to be ...

I’m very interested to see the results of these - hopefully you can do some REW measurements before and after.

Oo good shout, I'd forgotten about doing REW tests. I'll do one one immediately before & after each stage of the treatment (floating the housing box, hangers, loose insulation etc)

How's this for the hanger layout? Hangers from Above.jpg 12mm core, 50mm RWA45 on either side. 21mm gap between the hangers Angle is 40° (according to Stuart & Gregwor this angle tends to work well, though they're not entirely sure why) And here's how I'm going to line the cavities: lining.jpg T...

As hangers are also known as wave guides I guess their purpose is not simply to be a hanger for insulation like a hanger holds a shirt in a wardrobe; I feel sure as an amateur acoustician that their purpose is to help guide the sound waves so that they have a longer path in and out of the trap, mak...

I wonder what surface density you are wanting. Around the 500kg/m3 is pine, lighter chipboard and plywood.

I have heard some people make hangers with ply, but it'd need to be fairly low density (conifer, maybe?)
Stuart has said that cork or thick cardboard can work too

Just so you know Glenn (gullfo) from John Sayers suggested I go with 50mm on either side of the hangers & position them as close to each other as I can get without them touching. He also suggested that the insulation lining around the hangers be deeper (100mm ideally) These are exactly the quest...

ALSO For the acoustic hangers, how thick should the insulation be on either side of the hanger? In the diagram below it suggests 25mm but I've seen Stuart & others recommend 50mm. Which is better? More panels with thin insulation or fewer panels with thick insulation? In this thread Stuart says ...

I have some questions for the stages ahead, if any of you guys are able to help me out: - For the insulation I'm told the UK equivalents for OC 703 and 705 are Rockwool RWA45 and RW3 respectively. What should I use for what? Can I just use RWA45 for everything (hangers, loose insulation, panels etc)...
