Default Glass Speaker Cabinets

I couldn't really find any information or discussion on the topic. How good is glass in terms of making a speaker cabinet? I know it will look ugly if stuffed, but I am wondering more about the acoustic properties. I read something about a guy making a cabinet out of granite and it supposingly sounded pretty good.

so what about glass?

Depends how thick it is just like everything else. If it's two inches thick it'd probably work but it would have to be stuffed unless of course it was curved. of course then it would be prohibitively heavy very fragile and let's not forget extremely expensive.

I was thinking more like a wine bottle. I believe someone put 2 inch drivers in a pop bottle around here, but pop bottles are kind of flimsy so I thought glass might do a slightly better job?

I remember that too.... I thought it was a wine bottle. From a couple years back, IIRC.

Cheers!

I've just built a pair of TABAQ for tangband w3-871 in 18mm marble. The glass idea is very cool, and probably would sound similar. Mine sound great (they're stuffed though), but my ears are not trained, and I don't have the equipment to measure anything, at the moment, though I think diyaudio might become my new hoby.

I think the trick is to build them thick, so you don't get any ringing when you tap them.

I can only speak for myself, but I tried some Tang Band W3-871 drivers in a plastic pop bottle. It was surprisingly effective.

There was an idea around, I don't remember who from, to kick the bottom out of a glass bottle: Put some gravel or lead shot in the bottle, shake, crack!, out goes the bottom.

I'd really like to hear one made out of glass. I used a 1 liter pop bottle, IIRC 1.5 liters was a nicer thing to have.

I am definetly going to make these, I think I'm actually motiviated to do this now. How the heck do you "kick" the bottom out of a winebottle? I was planning to saw / cut it. I just need a pair of bottles big enough for a 3" driver. hm. wish me luck! i'll keep you guys updated. The drivers should be here in 2 weeks I think.

Unless bottle-shaped as above, how do you propose to seal the joints?
Any glass approaching a 1"> thickness would be very heavy and very expensive. On top of that, it would need to be tempered--
Not saying it's a bad idea per se, there are some hurdles though.
