ar_pro Posted November 16, 2015 Report Share Posted November 16, 2015 It's a film capacitor.http://www.aliexpress.com/item/Imported-RIFA420-series-film-capacitors-4-7UF160V-475-160V4U7-pitch-28mmCertain-discount-is-given-on-large/32241772942.html Link to comment Share on other sites More sharing options...

DavidDru Posted November 17, 2015 Report Share Posted November 17, 2015 Those look nice. hopefully someone with experience with these says leave them alone. My guess would be that they are fine. They are not that old. Link to comment Share on other sites More sharing options...
iso Posted November 17, 2015 Report Share Posted November 17, 2015 Yes... they are similar items that are usually used as upgrade parts to bipolar electrolytics. I would not change anything in these crossovers unless you are shure that there is some fault. Construction is very nice, like David said.Best RegardsKimmo Link to comment Share on other sites More sharing options...
djcheung Posted November 18, 2015 Author Report Share Posted November 18, 2015 i am just having an issue with the output levels with the mid/tweeter units.The left channel is somewhat louder than the right channel.I have swapped the channels and then the units but the issue still exists.So I think there is a problem with the placement of the speakers.I think they like to be placed in open space, far away from back and side walls.I think the left channel is too close to the side walls and maybe the wide dispersion is bouncing off the wall !No, I will not touch the XO after the channel swapping exercise.I think they should be good for a few more years.David.

DavidDru Posted November 18, 2015 Report Share Posted November 18, 2015 David. When you say you swapped the units do you mean that you swapped the speakers between the 2 locations? Or the drivers between cabs? Link to comment Share on other sites More sharing options...
djcheung Posted November 18, 2015 Author Report Share Posted November 18, 2015 Each speaker comes in two units, the bottom house the woofer and the upper detachable unit house the 2 midrange drivers and one tweeter and the crossover circuit.Not too sure whether there is another XO circuit for the woofer section. I haven't investigated more yet.I swapped the upper units but the bottom units stay in the same location. Link to comment Share on other sites More sharing options...
