Working On A Project

My boys are busy making bigger speakers for my sons room.  Joey is now on his summer vacation and his dad promised that they will fix his music corner and assemble big speakers for a better sound quality.  They have asked me to pass by the hardware to buy them t nut and other stuff on my way to the grocery store.  Both are too excited to finish their project right away.  I just hope that they will also do something to control the sound  that will be coming from his room; I don't want out neighbors banging on our doors telling me to turn down the volume.
