i have a nice DR. i often adjust the treble knob very low...very. i like to use the treble knob, but sometimes i wish it went LOWER! so, question, without changing anything else: i bet there's a spkr that will do that? (maybe i can even go the other way with the treble knob...more than i usually do. that would be interesting. it's not like i never turn it to 5 either, i have, i will.) thanks!
