Yes, that's what makes this project workable. I used nothing but hot glue on phase 1 of the spiral but I had to keep telling myself not to tool it like caulk.

The skin has almost grown back on my finger.
I just dripped hot glue on my arm today. Ouch! I actually smooth the hot melt like caulk with my fingers but there is a trick: flip your finger around so that the finger nail does the tooling. Don't do too long of a stretch and you won't burn.

Based on comments that a pleated paper surround isn't necessarily bad, I went ahead with those cheap drivers into my 'Wedge' mp3 player stereo foam core build. Here is the box getting stuffed with pillow fill. The amp and transformer go into the right TL.

It doesn't seem to cool as fast on your skin as it does on your project.

I finished the build of the Wedge TL mp3 stereo player using the cheap Microcenter drivers and amp. I put some magnets on the original grill covers to hide the ugly drivers. First listening impressions: not so good, I think I have to play with the stuffing but it sounds tinny, maybe worse than original plastic cabinets (which I modded with pillow stuffing so they weren't too bad). This also might be a case of the odd triangle shape of the TL contracting and expanding. Usually, a basic TL sounds better than tiny box. The form factor is convenient though and it sits nicely flush against wall on the back of a desk if your desk backs against a wall. I will post before / after sound once I finish tweaking stuffing - good or bad. I am hoping to make it the norm that folks share the sounds of their creations as well as photos.

I think progress can be put in the new Cornu Spiral thread, we can keep this one for general foam core speaker projects. Either way though is fine but this one currently has bigger viewership if publicity is what you want

May I offer a tip? As one who has experienced the 'kiss' of hot glue, I now wear disposable latex gloves when using the glue gun. This has saved me considerable pain.

And looking towards the new year, when I hope to have a bit of free time, I am planning on giving the 27" Cornucopya a try. An old friend who died a couple years back left me a pair of DIY speakers containing Altec Lansing 405A (4.5" ?) drivers. The small sealed cabinets produced nothing in the bass region, so I have been wanting to try them out in something fast, cheap, easy...

Cheers, Jim
