I did replace two of three of the mid-range caps, as well as three of the five tweeter caps.Can you let us know which caps you replaced? the value of the caps ( ie: 2.2uF 100V)?
HELP AFTER MY MODS, My tweeters are subdued and weak-
So I have a pair of Mirage M1 speakers, I changed the caps in the crossovers to Jantzen Superior Z (for the tweeters) and standard z for the mids and bass.
I also changed the internal cabling to Supra Classic 2.5.
First Impressions- Not burned in yet
The highs are there but really recessed in the background. Theres a song I reference and it has a steel guitar solo, I can bearly hear it through the vocals because its seems recessed so far back.
SO HERES THE QUESTION- Is that a symptom of unburned in cables and or caps, or is that just what Supra cables give you?
When I changed the internal cabling a few years back on the same model speaker, I used DH LABS t14 Silver plated cable, This had the opposite effect, it was super bright and fast, but it smoothed out and the brightness relaxed, leaving a lot of detail but not so much your ears bled.
But here its the opposite, its dull on the top end and the vocals kind of take over and blur out the top end.

How can I tell what the resistance should be, that device that Tim posted , will that tell me the correct resistance? If I measure the other crossover that I haven't changed any electrolytic caps out of yet.This one cost more, but easy to read: https://www.amazon.com/Peak-166225-Atlas-ESR70/dp/B005NIBEYU/ref=sr_1_1?s=industrial&ie=UTF8&... Yes, you can swapping those resistor to fine tune or simply add a resistor in series to the new caps to make the ESR same as the existing caps. |
The caps I replaced were:C8=4X3.3uF=13.2uF and you replaced it with 3X3.3uF=9.9uF? These cables appear to be around 25 years old. What if a connection was broken poor inside of your cable box or if a part was going bad? Not sure that you can open this thing, but I'd take a look there... I think just for kicks I'll try the other Tara cable, I would think it would be less likely to have both cables have an issue.Any outcome? |
I think what Ill do is buy a tester that can check the value of the caps as well as check the ESR and see what pops out at me.Totally agree, and this link is worth a read: http://www.diyaudio.com/forums/multi-way/282847-original-electrolytic-caps-better-than-new-upgraded-... |
