So I ask myself, self, why does everyone worry so much about this? People love the presentation of single driver speakers, they love the high efficiency; they have a problem when using a crossover to another driver, but still long for something more, be it bass or high treble.... I use very inefficient speakers driven by 3.5 watt mono amps; I have a Richter Scale crossover that allows me to get away with this. I have dynamics; I get to listen to my favorite speakers and I have very refined bass. Get yourself a crossover that allows you to correct the low end, (it also has a frequency anlyzer and contouring ability). We can have our cake and eat it too.
