Crossover design question, Experts needed!
So I have been looking at a lot of factory schematics from Cerwin Vega and I have noticed that in the early to mid 80s they started using inductors and capacitors to bridge the positive lead to the ground. Sometimes when they did it with the cap they also added a resistor. An example is in their...- Yester_Year

OK to replace bipolar electrolytics with film caps in crossovers?
I have a couple of pairs of Sansui loudspeakers (SP-1700 and SP-X9) that I am considering recapping as a preventative maintenance measure. These days, of course, it's easy to find film caps in the larger capacities where bipolar electrolytics used to do the job. For example, the SP-X9... -
