If he ever hears rattling or crackling sound in the future, during certain bass frequencies, it’s most likely the dreaded KLF glue failure issue. Lots of information on fixing that on the forums. The KLF is an awesome sounding line.
I purchased these crossovers to try with my FrazierStein speakers. I’ve decided to pass them on. If anyone wants the ALK’s, I’ll offer them at the same price as originally offered by Heaterman. $250 shipped.
I’m passing on it fella’s, not because it isn’t a great deal, but the enclosure won’t meet my needs for what I had in mind. Someone should grab this as the RCA connectors and switch alone make it a good deal!!
