just wondering what's the lifespan of an ICE speaker before it kaputs?
Always depends on application.
If you would like to do hair tricks with your speaker, well its hard to go 6 months.
If you like moderate and SQ application, would say 4-7 years before speaker spider and surround start weakening.
If you would like to make your speaker as a decoration, i.e. put put it in storeroom, bookshelf, paperweight well I guess longer.
