pythagore Posted September 6, 2021 Share Posted September 6, 2021 I have a pair of cornwall 1 that is currently using the B xover, I would like to convert the xover to B2. Per the difference between the B and B2 schematics, I only need to do the following: - Woofer circuit - add a 20uF in parallel. No Change to Polarity +/- - Mid circuit- replace the 4uF with 3uF. Change polarity to -/+ - Tweeter circuit - add a 245uH in parallel. Change polarity to -/+ My only issue is that I can't find a 245uH inductor in Canada, can a 14AWG 0.24mH (240uH) be used as a replacement? Thanks, Quote Link to comment Share on other sites More sharing options...

pythagore Posted September 25, 2021 Author Share Posted September 25, 2021 I have changed Cornwall 1 xover from B to B2, I am glad that I did. B2 provides substantial, very noticeable sonic improvement over B. 1 Quote Link to comment Share on other sites More sharing options...
