  1. At least 40 hours of Dub-step with the bass knob at full boost; doesn't have to be loud. Just shut the door and go have dinner and a movie. Then, I'd look for "Unforgettable" by Natalie Cole and "The Book of Secrets" by Loreena McKennitt and listen for all the cool nuances.
  2. Hi W & T! I could not find any data about the Pyle woofers using the number in the pics. Do you have any other model info?
  3. If they sound dull and recessed, caps may help. Use a good film and foil cap. I have not cared for the sound of metalized caps.
  4. Swap the + and - leads in ONE place.
  5. The crossovers look like the ones in my 1979 models. I would not bother changing the capacitors unless they sound a little dull or recessed. That is, the sound should seem like it is coming from a little in front of the speakers. It your sound distant or reserved, use a good film and foil cap. They will not he inexpensive. Solen, in France, looks to make two different film and foil caps you should be able to purchase easily. There maybe others in Europe, too.
  6. OK, good. That's plausible, but since lots (most?) Inductors are custom wound, wouldn't changing the diameter or wire gauge be a better solution? This came up while studying for my amateur General license and I just can't see giving up circuit real estate for 2 parallel inductors.
  7. Dang! I really hate that I picked this week to go off and work! Thanks for posting, Michael!!
  8. You misunderstand. What you linked is what I already know. That's basic circuits. What I want to know is why an engineer would parallel inductors, rather than build/buy one with the correct values.
  9. I know what happens when inductors are paralleled, but why would you ever do that? Same for series? This is asked in the realm of relatively low power electronic circuits in radio transmitters/receivers, like 20 to 1000 watts. But it could apply to crossovers.
  10. Salve, Frakka! I will recommend a good film and foil capacitor. Solen in France seems to make 2 lines of film and foil capacitors. You should be able to get them easily. I normally do not care for the sound of metalized film capacitors, they sound brittle, or have a metallic edge to their sound, but they are inexpensive. Film and foil capacitors have become more expensive over the last 5, or so, years, but they are worth the cost. Your dust looks just like my dust!! 😆
  11. I don't hear it. Perhaps a room issue?
  12. I do it in my music room. You'll want a preamp. Adjusting volume and tone with a laptop is slow and frustrating. I feed a Mackie 402 mixer from my laptop with 1/8" headphone to phono cables. The Mackie feeds various mics and the laptop to my Yamaha receiver. It drives KG2s or Heresy IVs and sometimes a subwoofer. My audio path is all analog; the D/A voodoo is all in the laptop. The sound quality from CDs is very good. Try it, I think you'll be pleased. Some of you would be appalled at the gear The Chief uses to demo speakers in the lab, including Jubilees.
