You have liquid nitrogen?!
The stress would probably break the whole thing but it's worth a shot. wear heavy gloves and eye protection, so you don't get hurt.
I was going to form a thin strip exposed in the glass with duct tape or something a little thicker. then spray a light layer of nitrogen on it, where the exposed strip would be the coldest, then just plunge it in hot water..
One method I recall reading about: tie a cotton string around the bottle at the point you want it cut, soak with lighter fluid, light string... bottle cracks under string. You'll probably need to sand the edge at that point.

yeah, I've seen the string tactic. you still have to soak it in cold water after that. hence my reversal process of using liquid nitrogen. it should do the same thing..
For glass cutters to work properly, ie. a nice clean cut, standard practice is to score one side of glass, and tap the opposite side till the cut "runs". Not too easy with a bottle!
Good Luck, Don

They have little tools that have a handle and a weight at the end to do the tapping. You insert it into the bottle.

Just now realizing how many potential "speaker enclosures" I've emptied and discarded over the years!! (sigh)

I know this is now slightly off-topic as the project is looking at bottles, but does anyone know what is special about (as in, what is it, how do they make it, etc) the "super silent glass" that perfect8 use? (www.perfect8.com/t_ssg.htm).
Now that someone has done it without apparently needing stuffing, it's piqued my interest in building a glass box cabinet - preferably one without edge seams, eg a hollowed out glass brick, or a dali-style semi-melted box.

Just thought I would point out that champagne bottles are thicker glass than normal wine bottles. They are also larger diameter at the punt. A magnum (1.5L) would be better still.
These ones here use rectangular glass cabinets.
The damping is done via some flow resistance on the back side of the drivers (look for A.D.T). The use of a passive radiator instead of a reflex tunnel helps great lengths too in preventing resonances from exiting the cabinet.

Simple bottle cutters have been around for years. Usually 2 cutter wheels and a roller or 2.
Cost about $30 - a bit much for what they are.

yeah definetly. just mount your simple 5$ glass cutter on a flat surface.. eg a 2x4. then spin your bottle around it.
Not a bad idea, the ice-speak. Surely it's been done at one of those ice-sculpture parks? Perhaps mold it rather than sculpt.nukaidee said:

These aren't too bad looking, though I thought acrylic makes a poor cabinet material due to it's elasticity:
