First, thanks mrybczyn for the idea. 🙂
I'm well into my first BiB with my RS100's ... initial impressions were 😱! I've never heard such detail and midrange clarity like this before. My son plays the drums and I'm tempted to record him playing his cymbals and re-play it through these speakers as the resolution of cymbal and snare notes is fantastic. I don't have an ideal room to set them up for good corner loading but loading them against an armoir positioned diagonally in a corner must be good also. And what enormous sound for such a small driver! At first I was loathe to put any stuffing in there even though they did at times sound like music coming from a tunnel.
I built them out of pine (I know, probably a no-no) and though that may contribute audibly it certainly isn't the biggest problem. I left the top of the inverted bib off and seal it up with the top weighted down so they are sealed for testing, but I can lift the top off to make adjustments to the stuffing. Using the Bigger Is Better 'BIB' Cabinet Dimensions - ZillaSpeak recommendations I stuffed from the closed portion of the line all the way up to the top of the cabinet including behind the driver and it's cut the frequencies coming from the base of the enclosure to somewhere between 1 - 1.5kHz. I'm using PE Acousti-stuff.
My first question is how densely should I pack the stuffing? I've stuffed both of them relatively loosely but I wouldn't call it "packing".
Secondly, if I now need to stuff down the back side of the slant how shall I attach it? As it is inverted it somehow needs to be attached to that slant in order to keep it from falling out. Should I attach it incrementally down the back of the line or should I attach it all along the length in a thin layer and then build the thickness up? To attach it I was thinking about using mist netting or even onion bags stapled at the top of the fold and hanging down and opening it up to insert the stuffing. I also thought of using wide double backed tape but expect that's a short term solution. I'm guessing here .... there are a lot better ideas out there huh? 😀
Feel free with any other ideas for treatments as i know that lining with felt has also been done before ... I do have some PE damping material as well.
This is a really fun project. My 10 year old son is having fun with it too.
We started tuning it together stuffing a little bit and playing test tones and then adding stuffing and listening again, we could here the frequencies increasingly drop out of the bottom ... making it a science and construction project too.
Cheap as dirt + science project + startlingly good = C,mon! 😀

I do not stuff densly, you want the stuffing to absorb high frequencies but not block air flow. You can sew or staple cheap fabric together to hold the stuffing and then staple or glue the fabric pocket to the top of the internal board if you need more stuffing then fits in the front section around the driver.
Thanks for the info ... I've got some leftover grill cloth ... hopefully I'll get to it tomorrow. I guess I'll start nearest the driver and slowly extend the stuffing down toward the bottom of the cabinet as needed, maybe stitching some loops around the stuffing to hold it in place.
