LOL!

That's an excellent idea about the soft rubber, especially as the floor is not 100% level. I will make it so.

Cheers!

I've been busy and really didn't want to rush the process of fixing of the soffit structure sole plate to the floor, so it took a bit to get round to doing it. Had I been able to screw straight down through the plate into the subfloor it would've been easy, but doing this would have ruined the hardw...

Thanks Glenn, that's useful to know. I cut the sole plate for the soffit structure this morning before a session. First I measured and marked the dimensions onto masking tape on the floor, then cut the stud wood to size. Working out the correct angles to mitre the baffle face corners was a bit of a ...

That's ideal, thanks Glenn.

The build has begun, thought I'd share something I've been pondering. The wood coloured beams in this picture represent the existing house structure. The red stud represents the verticals in the soffit structure. truss.JPG My design has the red beam stopping 6mm or so short of the sloped ceiling. It...

Good to see you back and also getting back into the studio build. I know John Brandt has been subjecting many standard acoustic designs and assumptions to laboratory tests recently and revised his thoughts accordingly. It's great that you have the opportunity to take advantage of this. KH310 speaker...

Thanks Glenn, good plan, I already have one of those. Thanks for the swiss cheese tip Stuart, that makes things much simpler. I had assumed one would keep the holes as few and as small as possible on the speaker box to prevent sound "leaking" out as much as possible, but I suppose the insu...

Thanks Glenn. With that in mind I'll proceed with the current plan and attempt to test it to make sure there are is no significant structure borne transmission. Do you know if there's a reliable way to test for this? I imagine it might be crudely done by running a slow sine sweep through the speaker...

Thank you Stuart and Glenn, your posts are very helpful and have opened up some significant avenues of thought. I'd like to explore some questions if I may. Please don't think I'm being dismissive, it's more about expanding my understanding of the acoustic properties of this structure. With this in ...

Thanks Glenn. I've built one speaker box from 18mm OSB. Later on I'll beef this up by adding two layers of 5kg/m2 MLV to the outside. 2023-10-18 14.32.19.jpg 2023-10-18 13.14.19.jpg Drilling holes for the mounting bolts in the correct locations was quite challenging. The bottom bolt is 3/8" UNC...

Thanks Glenn, much appreciated. I reckon I can get a close fit of the bezel to the speaker with the help of my router and a profile matching tool I bought. A very good idea to make the bezel removeable thank you! There's already a couple of proper electrical sockets that will end up contained within...

Soffit time! The speakers are the Genelec 8030s, and their curved shape will make things a little trickier than usual. As discussed earlier in the thread I have a master plan for this. But a few details first concerning airflow round the speaker to allow the bass reflex port to work and also to prov...

LOL, even better with the tool belt! I use a drywall drill bit that stops the screw going in too deep. Very effective.

This is looking great Sam, nice work. I can empathise with the strain of fitting so many 100mm screws. After having to screw many extra long plasterboard screws to secure second layers of plasterboard on to studs, I bought a small 12v drill driver and impact driver set. These are much easier and les...

That would be an amazing thesis. Jackson Pollok patterns, what a brilliant description Glenn. I seriously hope this proposed thesis would conclude it to be the best pattern, because after the all the demanding tolerances required in studio building, making these patterns provides some much needed le...
