DavidR Posted April 3, 2015 Report Share Posted April 3, 2015 Ever since re-capping my AR91s with PP caps I've wanted to do my AR90s.I have a question on the tweeter crossover difference. The 91 has only a 4uF cap in series with a .2mH coil in parallel and the AR9 and 90 have a 0.105mH coil with a 4uF and 6uF caps in series.I'm wondering what the 4uF and 6uF in series does. Is the difference only because of the coil difference? Link to comment Share on other sites More sharing options...
