Rolls Crossover Question SX 21
 
1 Attachment(s)
The Rolls SX 21 (24db) is a bare bones crossover with a few basic features. I have read reviews that said the polarity is backwards, which is not the case but what are the options to correct phase?

I had some success with this project where the phase was 90 degrees [maybe 180 degrees] off; in any case there were no signs of a dip by reversing driver connections. I thought there may be a simple answer and added a 12uf cap at the tweeter, which was a huge improvement, although the tweeter connection needed to be reversed for the straighter response.

Are there other options?
Is a reverse connection a issue, or it just about the final response?

Many thanks!
