it's the Sayers slat spacing - it's pretty specific that said, when i do corner slats i tend to tune them for LF absorption rather than wider broadband.

the hard backed clouds can help in just about all small rooms. they're less effective in larger spaces for obvious reasons. the thing is - you can adjustment them (i use plural because just like wave guides (which they are effectively that) there may be several in a row) to accomplish the change nee...

on the hard back cloud (one of my inventions lol) i usually like to use chain link on hooks so the angle and position (vertically) can be tweaked. i run the chain through soft rubber tubing to keep it from potentially vibrating. easy to cut to length.

you could start with the single room and add a vocal booth later if the gobo approach isn't sufficient. an inside-out design can be made to be an RFZ with appropriate configuration of the absorption and any necessary panels to manage the impulse response of the room.

not sure if Pella is available in the UK as they have top end windows which are wood wrapped with aluminium the wood is machined to fit the metal frame resulting in high density and a resilient exterior. i believe Martin, and some Andersen products may have similar lines.

i started an answer on John Sayers - but i'll give roughly the same advice here - i revised it a bit - you should create the symmetry you need by added a partition wall to the left of the desk position (and i didn't add this previously) seal the garage door to the right. the partition should go back...

a lot of work on this topic was provided on the old studiotips forum by Eric D and others.

nice work!

note: for those where celinet isn't available (like US) a similar product is called Tectum V - wood fibers and portland cement - very often used in gyms and auditoriums. https://www.tectum.com/ of course there are lots of options...

apologies. i saved it as SU 2017. then (by instinct) hit Ctrl+S which unfortunately then automatically re-saved it as 2021... this is the 2017 file. updated file in original post.

if you have access to SU (such as the free downloadable Make 2017 version - the web version doesn't support dynamic components) attached is a dynamic component for sizing up a simple soffit wall.

the absorption you described would target 100hz and up, although how you took the measurements would be helpful.

yes, the baffle plate should ultimately be non-symmetrical for purposes of limiting resonances, but also close enough to approximate an even distribution as well so 6 inches or so should suffice

the shelf for the speakers is just one option for mounting. i prefer the entire stack open top to bottom. speaker box mounted on frame and speaker decoupled from that, or speaker box decoupled or even on mass stand. the plate below the speaker is to extend the baffle to match the sides and top of th...

you can leave the top open however as the bottom is close, you extend the baffle with plywood behind the face insulation (which you may have done already). this provides the baffle extension needed and because it's (mostly) soft, you help with absorbing reflections off the front of your desk/console...
