I have a pair of RT5's that I listen to every day and they still sound great. Unfortunatly, about a year ago when I was upgrading the internal wiring of the speaker, I got a little too close to one of the cones with the iron and it created a heat dimple with a small oval shapped perferation (about the size/shape of a grain of rice).
What effect would this have on the performance of the speaker itself? I can not hear the difference from before the dimple to now. Should I spend the money to replace the driver?
