Has anyone done an a-b comparision of KHorns with and without grille cloth (over the tweeter/mid speaker). Audiophile dogma dictates that grilles over high frequency speakers are a no-no. Does this rule apply to the KHorn? Am tempted to remove the cloth covering the tweeter, and perhaps the mid as well.
I use triode amps with my '72 vintage KHorns, so I am not trying to mute transistor edge. Also using the ALK x-overs, and would like to hear all that they have to offer.
Thanks!
