Hello everybody, I am new in this forum and I would like to share some things: I'm the happy french owner of a pair of RF63 and I have heard that it should be possible to improve the quality of the crossover addind a 9V battery to bias the capacitors in serial with the HF driver, like for JBL speakers for example. What do you think about this ? Does anyone have already do this and were can I find the shematic of this Xover? Thanks in advance Jacques
