Tell us about yourself!
i made one and it works great, as for psi, i just run it at whatever my 14cfm gas powered compressor puts out, id say around 120psi. one slight warning, make sure the sand your using is screened, i thought i got all the large stuff out of mine but i guess i didn't and before i could figure out why the sand stopped, the bottle exploded, so might wanna watch out for that and probably not run it around 120 psi lol. but it works great, way better than a bought one from harbor freight that i have
sorry, works been pretty crazy, been getting home at 3am, it actually sounds alot better than i thought, nice job. i just finished building a portable speaker for work thats a bit more powerful with a 36v 9a power supply and 2x100 watt amp but thats because i work at an event center that was formally a home depot, its rather large, but for the money spent, i like your more lol
private video, cant really watch it
yea that sounds like it would work fine, its how everything is recorded for the most part. as for the speakers, i dont think you need to worry nearly as much for higher end drivers, high end frequencies not price. i think you really have to worry about the box flexing and affecting the sound more for sub woofers and woofers but thats purley speculation and not based on anything other than whats floating around in my head
reading that comment again, i think it came off a bit more hostile than intended, sorry bout that. i fully understand the whole 'find it instead of buy it' i do it all the time. do you have any means of recording them other than your phone? im curious as to what they actually do sound like
its an awesome idea but they must not sound that great since you didn't use the recorded audio in the video,there is no way those speakers sound like a studio recording. I think the cd cases would be a bit to flexible to make decent speakers. why not use some 1/4in or 3/8in acrylic?
