Hi all. I have owned a 3.1 system based around Infinity P362s and C350 for around 10 years. I recently moved and wanted to add rears so I picked up some P162s on ebay. As soon as I hooked them up to test them I noticed they sounded very muddy. \n\nI checked the resistance on both tweeters and found they were both blown and was able to get a refund. The tweeters were discontinued, but infinity told the the tweeters from the C350 center channel were close enough so I ordered a 2 of them. The housings were different but after some grinding I got the tweeters installed. \n\nOne of the speakers sounds good, but the other still has almost no highs above 3000hz. I used REW to generate test tones and I am barely getting anything out one of the speakers above 3k. I tried swapping the tweeters but the problem remained in the same speaker so I think I can rule out a DOA tweeter. That leaves the crossover and the woofer. I assume a bad woofer wouldn't cause these symptoms. So that leaves the crossover. I pulled the board out and there was nothing obvious like a visually leaking capacitor. \n\nAny advise on where to go from here? Is there anything else to check before I either try to replace or rebuild the board? The capacitors are radial which I can't seem to find with the right specs so it will be a little messy if I have to replace them all with axial caps.
