Looking at the 3" to 4" full-range speakers at madisound and partsexpress.... I think I'd like to experiment with making some *cough* Bose style "cubes" that didn't need a crossover and would be supplemented with a subwoofer. I could possibly run them from a subwoofer's high-pass speaker level outputs. Any driver suggestions? I realize the high-end will be rolled off substantially. These would be for movies primarily. Music is secondary.
