Why are triangular enclosures not more common here?

Well what are the chances? Had to grab them.

Picked up locally for a measly $15. Random brand name of Opus One, can't find anything about them online.
Reasonably sized woofer magnet, simple crossover, lightweight enclosure but could certainly be modified.
Bright clear sound, decent vocals.

Two is better than one, one of the best shapes to reduce corner diffraction is the double pyramid, it also ( as far as I can remember ) create a dip in the midrange, thereby flattening the response of a " full range " driver, although you could stick a tweeter pod on top.
 
Cheers cracked case, I've seen a few ingenious youtube vids with upside down jigsaws.
My woodworking skills are slowly improving, mostly because of diy projects around the house. To be honest I don't where some of the members here find the time to be so productive, I always seem to have mundane chores to perform that take priority over mucking about in the shed.
 
I might brace and stuff the enclosure before running some eq on them initially before I think about heavily modifying them into a long dagger enclosure.
Coming across these decent sized ones for such a cheap price was most fortuitous 🙂

When the jigsaw does hit the wood, why not stick it upside down in a vice ( or better make a stand ) and feed the wood through.
That looks quite a bit more dangerous than using it the proper way.

The blade is now sawing away, sharp edges exposed, on the same side of the wood as your hands. The risk of cutting off your hands or fingers is elevated considerably - now it's more dangerous than a table-saw or band-saw.

Why "more dangerous", rather than "as dangerous as"? If the jigsaw blade should snap in use (which is not that unusual), the broken sharp piece is now likely to be ejected at your face or eyes, rather than at your feet.

Also, if things go wrong, and the saw starts cutting into your hand, how are you going to turn it off quickly? Clamped upside down in a vice, the on-off switch is inaccessible underneath the wood you're trying to cut.

To me, the whole idea reeks of badness - just a bad, bad, bad idea. The picture of the upside-down jigsaw in the vice looks like the "before" picture, under the newspaper headline "Man Maims Himself with Upside Down Jigsaw". 😱

I was watching some " tree house masters " or something on TV and the bloke was holding a piece of wood with one hand and using a circular saw with the other, he just missed his fingers on the unseen side. At least that wouldn't happen. It's like a table saw but you can go around corners. Having said all that I have NO objection to you pointing out safety issues, point taken.
