Level adjusting speaker drivers
Sometimes when I listen to various things it would be nice to turn up mid and Tweeter levels, and also bass too.
The speaker gets the signal and then it's split between the drivers by the crossover's, but what about the individual levels hitting these drivers. Would it be worthwhile to have a means to increase or reduce these levels?
Anyone ever done this and what tool did you use?
