ClintonH Posted January 29, 2016 Share Posted January 29, 2016 Just trying to understand why the tweeter is reversed in some of the RF series and not in others? I thought it might have been the fact the HF crossover is a 4th order (I might be wrong on that?) and LF is 2nd order (again could be worng on that) But I see that is wrong as the RF-7, RC-7, RF-5 all reverse the tweeter but the RF-3 which has the same layout does not.

pzannucci Posted January 29, 2016 Share Posted January 29, 2016 It is based on at least several factors. - order of the electrical crossover - phasing of the drivers - distance between the drivers - depth of the horn - crossover frequency It all depends on if the crossover when completed creates a good smooth transition between the drivers and if their sum together can be smooth or create a major notch in the crossover / overlap region. If there is a notch, many times reversing the phase on the driver will help the crossover region sum more correctly with some associated tweaks. Design choices. 1 Quote Link to comment Share on other sites More sharing options...
JJkizak Posted January 29, 2016 Share Posted January 29, 2016 If you have a Cornwall it would be difficult to remove the back every time you reversed the tweeter leads. JJK Quote Link to comment Share on other sites More sharing options...

Ah yes the horn depth/size must be the factor I missed. Thank you very much for that. Quote Link to comment Share on other sites More sharing options...
