soulpianoman Posted October 25, 2020 Share Posted October 25, 2020 Hello! Apologies as I'm sure this has been answered somewhere before but I am having difficulty finding the answer to this question digging through the forums. This is the schematic that seems to pop up everywhere when a search for the Chorus II schematic is performed. I am scratching my head on this - is the polarity correct on the tweeter or is this a mistake on the schematic? 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted October 25, 2020 Share Posted October 25, 2020 Appears to be to me. Color of tweeter wires correct. Is there a problem @soulpianoman ? Quote Link to comment Share on other sites More sharing options...
soulpianoman Posted October 25, 2020 Author Share Posted October 25, 2020 Thanks - I would think that the negative of the tweeter would go to ground like the chorus I does? 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted October 25, 2020 Share Posted October 25, 2020 It does on both so yes. The crossover may not relate that to you between the two schematics. Quote Link to comment Share on other sites More sharing options...
billybob Posted October 25, 2020 Share Posted October 25, 2020 You may be doing something else but, if you had the tweeter out and it got reversed, unless marked, could be easy to cross them. In which case , would sound out of phase. Quote Link to comment Share on other sites More sharing options...
soulpianoman Posted October 25, 2020 Author Share Posted October 25, 2020 I rebuilt the crossovers and changed to the Crites titanium diaphragms on this pair of Chorus II and want to make sure I'm hooking up the tweeters correctly to the newly built crossovers. The positive terminal is marked clearly on the new diaphragm, but I was just wanting to confirm that the schematic was correct in the photo above. Unless I am reading it wrong, it looks like the Chorus 1 schematic shows the positive of the tweeter going through the 2uf cap, 1 leg of the inductor and the other 2uf cap to the positive input. The Chorus II shows the negative of the tweeter going through the 2uf cap, 1 let of the inductor and the other 2 uf cap to the positive input. I wondered why it would be different on the chorus II?

OO1 Posted October 25, 2020 Share Posted October 25, 2020 here is the Chorus II Crossover Made by Crites Speakers on a wood board -------ZOOM in at the negative wire on the barrier strip ---------here is your answer ,and yes all wires are black - 2 Quote Link to comment Share on other sites More sharing options...
soulpianoman Posted October 25, 2020 Author Share Posted October 25, 2020 Thanks @randyh000. It looks like Bob builds them according to the chorus 2 schematic above (I think...the black wires are hard to trace!). I checked the chorus 1 picture on the Crites site and it looks like that the tweeter polarity is reversed (compared to the chorus 2) on it also in accordance with the schematic on the chorus 1 posted above - so both schematics must be correct. Wonder why the tweeter polarity difference between the two as they are almost the same with slight value differences? Much appreciation and thanks to you both for the help! 1 Quote Link to comment Share on other sites More sharing options...

314carpenter Posted October 26, 2020 Share Posted October 26, 2020 Edit. Whoa.....fact check. I initially F&#@d up this response. Polarity is reversed on the crossover side (within the network). The schematic is correct. You should not be reversing the polarity at the driver terminal. 2 1 Quote Link to comment Share on other sites More sharing options...
