I took the small rear panel off the speakers to reveal the crossovers. The two large black caps (47uf) are Electrolytics, the rest are Paper in Oil. All the silver caps are the same value (3.5uf), there is a single value used parallel in the midrange bandpass filter and six combined along the front for the series cap total of 21uf. A single 2.7uF is in series with the Tweeter. But where are the coils you might ask?
