Hard Drive Speakers

Afrotech uses three hard drives of difference sizes when making his hard drive speakers, this method ensures high fidelity. 🙂
“Why pay 500$ for Klipsch’s latest speaker system? You can make something that looks way cooler for the price of a DIY amplifier and some HDDs out of a dumpster. It doesn’t sound quite as good but who cares! There really isn’t much to say about this project… It’s fun as hell to watch, easy to do, and impressed the crap out of everyone I’ve showed it to.”
Afrotech Hard Drive Speakers

The Harddisco is amazing to look at, it doesn’t sound as good as the Afrotech speakers but there is no audio being pumped into these drives.
“Techno basics. “Harddisko” is an installation piece dealing with raw computer sounds. Rhythmic noises are evolving from sixteen harddrives, which are orchestrated through simple power circuits. By cutting the harddisk’s power in varying sequences and amplifying the peculiar sound characteristics of each drive, an unpredictable acoustic and visual interplay is taking place.”

Stephen Moore did a little experimenting before he modified a few hard drives into speakers. What tipped him off that the drives might be able to be used as speakers was the term “voice coil“.
“Reading the literature, this hard drive had seek times in the millisecond range, which would suggest usable frequencies up into the kHz range. High frequency signals (over 5000Hz) created unusable output. On the other end of the scale, low frequency signals caused excessive motion of the drive heads and a buzzing noise. I finally settled on using pre-processed program material, using Cool Edit (trial version) to implement a digital 400Hz – 5000Hz bandpass filter. The first tracks successfully played on my new speakers were AC/DC Hell’s Bells and Clint Black Killin’ Time. The track selection was based on easily recognizable vocals.”
