Hello to the forum. I been off and on over the last few years mainly reading posts and researching Polk Monitor Speaker component upgrades to the crossover. I have recently (this weekend) acquired a set of Polk Monitor 10Bís from goodwill for the whopping sum of just less than $32.00. The condition of the speakers on the outside exhibit a scratched up top on each of them on the wood grain vinyl covering ( I recently read a post where someone veneered their Monitor 10ís speaker with real wood. Good for him, I need to make notes on that for the future of these speakers). Also at one point four Ĺ inch screws were not very politely embedded into the bottom of each of the speakers (currently removed), which is where I believe the scratches on their tops came from. The grills came with each of the speakers but I believe who previously owned the speakers had a cat that used them for a scratching post, one side of one grill has been shredded to the wood, a cleanup and recovering of the grills is in order. On inspecting one of the speakers there was no 1 Amp fuse in its receptacle, it had a piece of wire wound onto it. Definitely shorted together there. The other speaker had a unknown rated fuse in it. I powered the speakers up even with the shorted fuse holder and they sounded great, but the tweeter on the shorted speaker was scratchy. So the next day a visit to Radio Shack and I picked the correctly rated fuses, and it cleared up the scratchy tweeter so I thought. Iíve been testing the speakers with a variety of music and once in awhile the tweeters get scratchy, is it possibility that the crossovers need to be rebuilt or is the tweeter (s) shot? I have a pair of Monitor 7 Series 2 as well, which have their own unique problem, which I will save for another discussion. I like to say thank you to the person that uploaded the Monitor Series crossover schematics, it solved my fuse question, I would have asked at one point.
Any recommendations or thoughts would be appreciated. The speakers definitely sound great, I am currently playing some Mozart Quartets to give the tweeters a bit of a workout, and at times the scratchiness manifests itself, mainly on one tweeter but I am not sure about the other. Also, is there suppose to be some fluid enclosed by the plastic dome cover over the tweeter? I could be wrong?
