MAKE Asks: is a weekly column where we ask you, our readers, for responses to maker-related questions. We hope the column sparks interesting conversation and is a way for us to get to know more about each other.

This week’s question: From the old days of crystal radio sets and through until today, audio electronics projects have been all about DIY. What audio equipment have you built, hacked or modified?

As a young man I foolishly overloaded the amps on a rather nice pair of Roland studio monitors. I looked up the frequency specs for the speaker and wired my own crossovers with capacitors to turn them into passive speakers. Now I power them with an external amplifier and they still sound beautiful.
