I have just taken delivery of an M553 crossover and wish to use it in my L300 ish project. For this to work the mid - hi crossover point has to be changed to give a x/o at 8.5 khz. Stock x/o is at 5khz maximum.
Has anyone been down this road before. It should only be a couple of small caps to make the change. I have downloaded the service doc but am having difficulty locating the appropriate components.
Strange that JBL would have restricted the HF range given the extensive use of 24xx tweets over the years.
I have e mailed JBL tech help but I,ll wager this forum is quicker.
Thanks all
