You don't want to use up amplifier power and tweeter power handling on 192 KHz stuff that the tweeter can't reproduce and we can't hear anyway. I haven't read the rationale (if there is one) behind 192 KHz but I assume the idea is to raise the frequency enough that the side effects from the LPF are above the audible range. _______________________________________________ Open-hardware mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-hardware
