It’s my understanding that speaker drivers perform better when they have less sound going through them. You may have noticed this in music when a band joins in on an instrument solo and the whole soundstage just seems to box in on itself. So splitting audio between more drivers should improve sound quality, but making custom cross-over circuit boards is tedius and confusing for amateurs like me. Luckily people have already been experimenting with virtual cross-overs. I first seriously thought...
