That does bring up a valid question. Whether downy fluff or heavier cotton matting type? I just bought a jumbo Dacron pillow at the Dollar Store for $5.

Unbelievably, my large glue gun blew up as I was leaving for the store. It fell over, was up side down and the glue seeped into the wires. No fire but I did have to change my shorts (pun intended) Proud owner of a new gun.

Yes, great way to test the stuffing. Stick a sock in it has a different meaning to us speakerholics.

I use rockwool for my stuffing. I gave up on the polyester and fiberglass stuff. I hear lambs wool felting works well.

Glad it wasn't worse. I usually walk away from the gun while it is heating up so I'll have to be more careful.

Hey Cal, actually I have been hiding under my bed for the past few hours waiting for the Mayan apocalypse to start. Checked all the TV stations so my courage is renewed.

So, both cabinets are glued with leads in place. Just have to cut holes, stuff the driver chamber, mount drivers and hook them up.

BTW, do you suggest tacking all the stuffing with a few drops of hot glue. Don't know how much actual air movement there is.

Should be about an hour.

That is not the place to spend your last few hours.

I just made a cup out of the rockwool and use friction to fit it.

If your estimates are anything like mine, we'll see you in a couple.

You did not cut holes in plywood before gluing? I do that on the foam core facers but that is easy with an x-acto after the fact. The friction and pressure from stuffing the stuffing holds it in place just fine. Maybe if you had used loosely stuffed stuffing in the channels, the glue would be a good idea. But too late for that now. Ok, we are waiting and the clock is ticking...

Default Bipole Cornucopya on Stands?

I just had a crazy idea for a cornu bipole stand mounted setup that is very "OB-like". Make a double layer spiral on a central board (hot glue in place). This board has a hole in it like original cornu. I would make the spirals left and ride handed on opposite sides. On the outside faces, have cutouts on front and back and mount two drivers wired in parallel for a bipole setup. This is no longer a wall mounted speaker but needs some cool looking legs to get it up to ear height. Kind of open baffle like but without a huge open baffle, just the cornu baffle, at 24, 28, 30 inches whatever you prefer. If you wanted to go nuts, make a really big cornu baffle to be about size as typical open baffles and get some monster bass with an 8 inch full range. I would do this with something like the Wild Burro Betsy at $100/pair. If you wanted to spend more on an 8 inch FR, maybe the Tang Band W8-1772. If you really want to cheap it out at 8 inches, do the Visaton 3020 BG20 (Sd is 214 cm2). Another slightly smaller option is to do a 6.5 inch full ranger. Has anyone tried the Visaton 3017 BG17 (93 dB efficiency for $16 ea)? The soundstage would be very big, and the bass would be killer. It would certainly be unique. What do you guys think?
