upgrading speaker crossovers

Well I am going to upgrade my crossovers and remove all of the electrolytic and replace with poly's. I was looking at the Solens also, I can get the metallized polypropylene, 100 mfd 400 vac, for $30.00 each at Madisound speaker store. I will probably wait until I get my gear back from conrad johnson.

As for the M1's the company may be a thing of the past but the speakers still sound pretty nice.

No worries, but the Mirage name is not what it was, thats for sure.
When I rebuild the crossovers I will post it. It could be a few weeks or so, I want to make sure I do it right and replace all of the elecrolytic caps, total of 6 per board, plus the 2 film. Christmas is coming and the upgrades on my cj amp and preamp are my Christmas gifts, so money might be a little tight until after the holidays, not to mention the wifes gift.

I was going to replace my capacitors with the same value just a different cap. There are electrolytics in there and I wanted to replace them with film caps. And if nothing else replace the 2 film caps, on the crossover with better quality same value.

Just got my conrad johnson gear back a few weeks ago. I had the mf2500 upgraded to the "A" version and the pv14l to the series 2 edition along with teflon cap upgrade. It is basically new equipment. I have just ordered Mundorf caps to replace the film caps on the Gold I crossovers and I am going to give that a shot first. After I will decide if I am going to replace the electrolytic caps. I was also thinking of replacing the tweeter but not sure yet.

If all goes right I might actually sell my mirage M1's that have upgraded SI dirvers in them from the tweeters to the woofers.

The two film caps I replaced were small in size and said RC on them. There were only two films per crossover, the rest are electrolytic caps and to change them over to film would be a hastle since the electrolytics are Radials and the fims are axial, very tight. Still breaking in the new caps and now that I have my new turntable I am spinning vinyl again!

Still thinking if I should change the electrolytics or not.

Well a lot of good feedback. I ordered Mundorf Supreme caps to replace the two film caps on each crossover. Basically the same value but I am sure better quality. I am counting on smoother highs and a little more bloom in the midrange. These caps look like they are in line with the mids and tweets. I can now say that after upgrading my equipment I know what better quality caps can do. Trying to replace the tweeters could be a challenge because of the cut out, so I am hoping that the caps will do the job. They are in the mail so I expect to get them this week and do the change over this weekend. As for the electorlytics it does look like they are for the bass section, I can always pull one and check it out to see if the values are still correct and if not maybe get a better electrolytic to replace them, just thinking. And of course now I cannot use my turntable to listen as the needle in the cartidge is no longer there. Its a MC that came with it, Music Hall MMF 7. I am not sure if it is worth puting a new cartidge in it or getting a VPI Classic, which is more money, that I was not counting on spending after having my amp and preamp upgraded, but this is a different subject.

Yesterday I replaced the 2 film caps on each crossover with the Mundorf Supremes. Did some listening and the speakers do sound better, the tweeters are not as brittle, the highs are still there but smoother sounding. I will need some time to burn in the new caps but I think this is what I am looking for, I will have to do more listening today. I just ordered my new turntable and will get it this week, can't wait until it gets here then I can try some vinyl.
For now I think that is all I am going to do the the crossovers, I want to let these new caps burn in, besides replacing those electrolytic's could prove to be a pain. Ever since I got my conrad johnson amp and preamp back from being upgraded the bass is great and they dig even lower, are more controlled and my soundstage is a little bigger, time will tell but it is as if I just purchased new equipment.

The electrolytics in question are 100mfd caps and are radial caps, the film caps are axial and are much bigger, so I dont know if I have the room to fit them. I can always take another look to see if it is possible to change them and if I can come up with a way to make them fit.
