I have a pair of Coral BX1500 Speakers that I purchased in Subic Bay, P.I. in 1972. I listened to lots of speakers but to me the BX1500 were the best. I still use them and they sound great. However lately I have noticed some distortion and I suspect the crossovers.I thought I would google Coral Speackers and found this website. I don't know if Coral Speckers is still in business or not but I sure would like to get the corssovers fixed!

I suggest replacing the capacitors with new polypropylene caps. If you can solder, you can do it yourself. If not, yake your speakers to a repair shop. Pick the capacitors yourself and take them with you though because very few repair shops will have the parts you want in stock. They may be tempted to replace the caps with non-polarized electrolytics, which aren't very good. It's better to use polypropylene capacitors.
Here is a set for you if I was close grab them for $175.00 just for parts http://chicago.craigslist.org/sox/ele/857659206.html
On the crossovers yes replacing the capacitors as well the parts layout can be a issue as well with having cross talk on some inductors.
With the capacitors I would lean to Mundorf caps and possible bypass capacitors, change out the resistors as well these will need replacement also.Inductors may have come un wound yes i have seen older inductors come apart as well. The trick with replacing the inductors if needed is to make sure you use a inductor with the same DCR.
