Friends....
One of my music buds has a pair of Yamaha S 4115H speakers. This is a big folded horn design with a 15" woofer and horn. He claims that one of the speakers does not reach a full output (compared to the other speaker). He mentioned testing the woofer outside the cab and it appears to be ok. So that leaves us with the horn and/or crossover.
I see that the horn xover uses a pad that connects across the inductor. I am guessing that this is used to change the inductance value and thus the crossover point. A 6.8Uf cap and .6mh inductor would yield a xover point of around 2.5Khz. So the pad would then either increase or decrease that xover point?
For testing, I am suggesting that he disconnect the pad and connect the negative side of the horn directly to the cap/inductor junction.
Anyone ever seen one of these crossovers before? I am wondering about the value of having the pad.
Thanks, Tom
