Ever since I came across this (I was perhaps 12) I've always wanted to build one - a friend of the family had one with a marble baffle. One day I will - and I have the perfect old barn to convert to house them.
But... it set me thinking. Would it be possible/desirable to build a similar thing for a BIB? Using two solid walls (and I do mean solid with no cavities behind plasterboard) and a front baffle of good play would it work for a BIB? If one got the cross-sectional area and height correct as per the BIB calculator? Such a thing would blend well into a wall and be hardly noticeable.
(Furthermore the WAF measurement could be enhanced by wallpapering the entire room and the front baffle with woodchip painted with magnolia emulsion.)
Last comment aside it IS a serious question!

It should be doable, just need to imagine how the partition properly divides the triangle.
I assume one loses the front slanted bits?

Thinking aloud here.... It'd need standard studwork say 68 by 33.mm inside to support the baffle and partition. That'll lose some volume so I guess that'd have to be taken into account.the area of the
port for the baffle would have to be the same and that would determine the angle of the partition?
Be good to toss in the definition of BIB
9 cubic feet of brick enclosure. ( 9CFBE )
corner loaded.
Would be a great way to Not Need
any resonant tube of some sort. ( NNARTSS )
Looks pretty cool. Regardless
Changeable, bolt in baffle pretty cool too ( CBB )
LOL just kidding, cant keep up on these terms.
Just curious

With one exception, all my corner speakers were just baffles across a corner and WRT the BIB (or any folded pipe/horn) its design is such that as long as the fold continues to expand going 'round the bend' towards its terminus is all that really matters.
One of the apparent curiosities of the BIB is that you upend all the usual choices - because here you start with what you've got - the ceiling height - and unless you're into major building works that's fixed. Playing with the calculator I realised that that in turn determined choice of driver and so on. There's something almost archaic about the process 🙂
In my case the ceiling is a high 2.75m or 9' in old money - it ruled out the cheap Monacor 5" that people like. So I plugged in measurements for an Alpair 12 and came out with a height of 2.28m - about the right ballpark from the ceiling I guess? SO that makes for approx 124 litres and internal dimensions of 28.1 and 19.87
