pet bottles usually can withstand high pressure thats why used for 'rocket' if use for sound solid lar!
its heavy enough and strong by itself and has nice smooth shape inside to nicely reverb your bass, so don't put any spoonge inside!!
comes with a free built in bass tube too =) wah hehe tommorow i cut it up and let you know how it sounds like la

i think i should do the big one?

*spoiler*
you can have it when i'm done with it =) just belanja me eet sushi at asia cafe =) drinks i buy myself

when i reach home from the office today.....
i straight away went to work cutting the bottle and i found out i couldn't cut it open with my small knife.. it was simply too thick
it was a pro because it would mean the bottle is 'strong' enough for bass
but pain in the ass to cut it open
so i went to heat up a nail over the stove and melted a portion of the bottle
the poke hot nail trick works... but it looks like an ugly mess, so i decided to saw it instead
i wrapped the bit with a cloth to keep my hands from self destruction =)

arrgh it was hard work with my puny bit and i wasn't getting round.... i'm going to my cousin's place later to borrow his jigsaw tool

Erm....good idea and interesting project. But is that bottle high density enough? otherwise the bottle will be singing....or you had the plan that the bottle singing together with the woofer?

hmmnn later i go sneak out to hardware shop for lunch and buy some parts to affix the speaker to the round thiny so that can test the sound later!

i bet the bottle will dance with the bass together.

pics! or you didn't do it!
