My favorite beer to image is a Belgian ale "La fin du monde" IIRC it has >10% alcohol and could live up to its name...

Sorry to correct you about it but 'La fin du monde' is not Belgian but Canadian ( Unibroue brewery). When it came out it was one of the strongest 'blonde' in the world at 12* alcool iirc, some Belgian could have been involved in its birth though ( some of their beers offers was from a belgian brewer recipe (Gino Vantiehgem).

Unibroue have interesting links to audio: Robert Charlebois ( famous Quebec's singer) decided to have a partnership with them and bought 20% of the brewery and in 2016, Dave Mustaine presented his endorsed 'a tout le monde ale' from them.

Have you ever tested a 'Kwak' or 'Delirium Tremens'? Both very nice belgian beer ( i've got fond memory of them).

All this and... i don't drink alcool -anymore- ( but spend a looot of time in pubs and bars long time ago and still have barmen around me -one specialised in beers obviously!).

Yes, its in there. It will take me a while to really get to the bottom of the differences. The sims did teach me a thing or two though. Or at least confirm a couple of things. We'll see if it brings any improvement. So many things have changed though. A raise in ceiling height, better isolation from outside noise, better damping panel placement... its totally different, even though it doesn't show that easy.
Most changes I'd recon are a plus, except for the raised ceiling. But I did get rid of that aweful metal ceiling. On loud sweeps it would add its own rattle noises. Not pretty :).

You already talked about the raised ceiling as a minus and i must admit i didn't understood why it could be a minus until it occured to me your loudspeakers are... line array! :spin: :D

Sometimes i should open my eyes... well, as you implemented shading i wonder if it will not be a plus in the end as for the high mid/ high you will still have a line but it may behave a bit as a point source ( and in this case the raised ceiling is a plus).

It could help to mitigate the 'wings' you have in vertical directivity (around 5k iirc).

With the disapearing of the rattling it would be a benefit anyway.

First sound:

First sound after overhaul - YouTube

I just connected everything and pushed play, so it really doesn't sound all that well as the correction was made for the prior rendition (without filters). It also clipped the phone mic, no wonder :D.

One subwoofer acted up, so this is with arrays + one sub.
Hope to fix the sub some time soon so I can continue with measurements and create the (proper) DSP correction.
 
Nice weather around these parts this weekend. Not that I need it now, to finish anything audio related. But it does mean other priorities will rob me of some audio play time. Jobs around the house to be more specific. Does it ever end? All I need is a couple of days, preferably having the house all to myself which simply doesn't happen all that often in this "new world".

I will get there... the biggest question is when...
 
Quite a few pages ago I posted about Banana plugs...

It turns out that the locking mechanism of these wasn't that robust. I've searched for other variants, like the Parts Express locking types, they all had one thing in common: fine threads on a small diameter. So I stayed clear from those too.

I ended up sourcing yet another type that I use right now:

These have the threads on a bigger diameter area of the locking pin. But did not have a plastic outer shell to protect the body. I used 'see trough' shrink wrap to cover the part of the body that holds the wire.

I used spades to hook up the impedance correction. Sorry, didn't take a clear picture of those yet... I might get a few measurements in today, but don't hold your breath just yet (lol).
