  1. Thanks. The oem xovers were working with out any issues. Just like to build xovers from scratch when I can.
  2. Don't worry about them, they will have no effect on sound quality.
  3. I am sure it would be a shot in the dark at first on a target value, but one could start to get an idea after making a few. Consistency may be a problem though
  4. wax paper and copper foil home made caps....that sounds like a neat exp[erment.
  5. Curious what you might have for speaker wire. Back in the day I tried a large heavy gauge wire (Monster Cable) on my new at the time Quartets and it made them sound as if the tweeters were disconnected. I went back to my previous standard ofc 14awg wire (10ft runs) and it made the speakers come back to life. Re cap the xovers would be the first step as mentioned above
  6. I have found the copper clad aluminum (CCA) to need two awg's heavier to have the same current capability of pure copper. Yea I agree it is junk.
  7. One example of higher Q: In theory we would want both capacitors and inductors to have zero dc resistance so the higher the Q the closer to pure reactance, Xl & Xc only without any R.
  8. I would like to get down to say 600-650Hz if the stock trax horn could go there. The Idea comes from the Chorus II has crossover points at 650 & 7000 and they are using the k61k trak horn to do that. One could use the Chorus II xover to get there since the k48e is also 4 ohms. That is if the stock horn can go to 650Hz. Or is it even worth the trouble for the 175Hz shift to the a55g mid driver?
  9. Might there be someone who knows what the lowest freq that can be used with the klf-20/30 mid range horn? I know the klf-20 is 750Hz & the 30 is moved up to 825Hz but could it be lowered below 750Hz? And if so to what? Just thinking of moving away from the woofers sooner and to take more asdvantige the a55g driver. It looks like a k701 (g700) would fit with little moding to the opening of the cabinet but would rather not go that route.
  10. Don't worry Jeffry, I was just answering karlson3's question and was showing him how I derived the number. It had nothing to do with you.
  11. If 57.125" represents a 1/4 wave then yes it is just over 49MHz (just below the 6 meter band of 50-54MHz) The formula is 468!/freq in MHz = 1/2 wave length in feet ! - 472 is some times used to adjust to real world antenna variables
  12. Jeffry, can you explain what your magic number (length) represents? 1/4, 1/2, a single wave or even a multiple of some given frequency? My amateur radio side is wanting to know what it might mean.
  13. Curious, silver in it self has a different tone to it, in my experience making a speaker brighter than with just pure copper. So has this magic length wire been tested with pure conventional copper wire? Same deal with the "combo" wires, has there been any testing with a different "mix" of gauge wire with and without silver being used? Again has this been tested with the wire combo being braided or not? I would venture to say that the silver content in the wire is by far the single most influential part and the rest has little to no value.
  14. Jeffery, If one of your "sources" that you trust were to say to put dog poop on top of all of the resistors in a circuit and it would make it sound better would you?
  15. To be able to measure a proverbial .0000000009 volts does not necessarily mean it would be affecting a circuit. Maybe your buddy had read from the same source to come up with the same wire length.
