[QUOTE="Jeffdachef, post: 8367747, member: 650438"] Got around to trying this method today, been wanting to try out this method awhile back but forgot about it till today. It worked out pretty well, from my tests, hit up a shop to compare it with an SMD Distortion Detector and it was spot on with the DD-1 -Buy a piezo tweeter, don't worry, it doesn't matter which one.
