I just recently dampened my KLF-30's Horns ( hi's & mid's), I just used rope chaulk (couple of rolls )from Home Depot, WOW what a difference this tweak yielded.My system seems to very smooth and more tonaly balanced, I also took DeanG's advice to upgrade the caps in the X/Over with Auricaps which are order and will recieve them on Friday . I'll let you know how that tweak sounds......hopefully by Friday night...
Good-Luck TWEAKING....!!!!!
