Mini cell is very easy to use.
It can be cut easily, and sanded to the shape needed.
When I was younger, we'd shape mini cell pads and seats to personally fit canoes and kayak seats.
We would use 3M spray on glue.
Anybody anything further to report? After almost a year of absence the urge to build has crept up on me again.
Hi Irishman,
Right now I´m quite busy, but I hope that in a few days I´m able to start a built thread about the black flowers, made from EVA.
All the best

Is corrugated plastic any good for speaker enclosures?
It is like cardboard only made of plastic of some type.
Used for hoardings and such. Not that expensive either and quite stiff, easy to layer and glue too I imagine.
Not sure how easy to cut but probably no big deal to get straight edges. Just not sure if it is thick enough. Might need to sandwich a couple of bits together for each surface.

Hi Luigi,
Is this what you mean - same as from what you posted in XKi thread? If so, it’s not what I would call corrugated but basket weave textured EVA - typical floor mat texture to provide non slip grip for walking or exercise like a yoga mat.

No. It looks just like cardboard (except it is white not brown) and is about half a cm thick but is made of some type of plastic. Will post a pic. I found some in a skip. Politicians use it for advertising purposes pre election cos it is waterproof. Quite stiff should work for enclosure.
this stuff. Corrugated plastic made from polypropylene resin I think. Cartonplast or Polyflute.

i tried corroplast panels and found it to be a PITA when it comes to sealing edges especially if you have angled cuts and it certainly doesn't have the damping properties of good old foamcore.
there's less surface area to bond.

And that didn't last long, at least with the EVA. Too tricky to work with for a rank amateur. So I've gone to 10mm foamboard. Would rather have done it in black, but never mind, white it is.
This is for the 0.53 Karlsonator and the W5-2143 Tang Band full ranger.
Im wondering whether the 10mm board is too much, whether I can get away with 5mm board. The only reservation I have is that the TB driver is quite heavy. Was intending to use a 5mm section of hardboard in behind it anyway.
I'd imagine the 5mm foamboard is vastly easier to work with. The 10mm stuff takes a bit of cutting, especially compared with EVA.
With the internal baffle, should I cut out the pieces individually or can I just score one side of the paper and bend the foamboard around minor corners (like between the baffle and the section leading up to the top of the internal divider. Also on the other side of the line for the smaller 40mm odd piece at the bottom. The fewer cuts Im thinking, the less chance of air leaks.

Hmmm... you mean this plan?
Mini Karlsonator (0.53X) with Dual TC9FD's
I still don't know who made the drawing for me. But the sims look great.
Hi X
Yes that one. Thanks for posting it.
Is it right to make those shallow baffle angles with just paper cuts and a bit of bending?
Or should I cut right thru get the angle precise and glue?

Shallow cut and bend for shallow angles. You can even do 90deg angles that way. Just remove a good trench of material to allow the bend to not scrunch up.
Okay, thanks for that.
I am soooo slow at this. Seems like it takes forever, but I guess you get a bit slick at it after a while.
I imagine getting the right cutting device makes a big difference.
By the by, I don't suppose you have you done any Karsonator sims for Visaton B100 or Faital Pro 4FE32 8 ohm?

X: One other thing I hadn't considered; easiest way to mount speaker terminals? Or do you just use bare wires out the back?
No B100 but maybe 4FE32. Use google to search thread. I have simulated hundreds of drivers. I just can’t remember.
Hot melt wires out the back through a hole is easy and fast. A round terminal cup hot melt glued in place works too.

Why not trying an enclosure with PP delivery boxes ? I did not try just giving a new idea. The EVA is very soft and sometimes hard to shape. PP on the other side can be molded easily and is easy to recycle where EVA is very bad for this (almost gone from packaging industry as it's going into landfill).
