ObHack: Not naming this post 'First post!' ObSpeakerHack: Setting up a pair of Radio Shack PA speakers for use in a recent stage production at my school. The first problem, albeit a minor one, was finding wiring that was the necessary length. I didn't even know they made 24 gauge wire in 100 foot lengths! 8-) The second problem was the speakers themselves. Either of their own accord or because of the PA amp that they were hooked into, they constantly emitted an annoying hum. The speakers in question had two 8-inch bass/midrange drivers and a horn-loaded tweeter. Turns out that the hum was coming solely from the tweeters, and the solution actually involved duct tape. In order to mute those annoying tweeters, I tore up some cloth I found backstage into two pieces, wadded them up, and duct taped them over the tweeter horns. Problem solved!
