  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.
  13. Look at the rear labels for all of the pieces and add up the max VA or max watts. Watts = Volts x Amps. So, your xfmr's 600 VA rating is essentially 600 watts (OK, not quite because the voltage sine wave is/can be out of sync with the current wave.) Leave some room for start up in-rush current and turn on one thing at a time. I think you'll be close to max capacity. FYI, fuses will pass 2x their rating for a short time before opening and maybe oversized. They are primarily for fire protection, thus not a good measure of load or capacity.
  14. If you can use balanced cables, why not go buy a pair of XLR mic cables and connect the pre to the power amps properly. Two cables running around the wall for 2 weeks can't be that bad. However, if you use the in-wall speaker wires, use both positive and negative for each power amp and don't use one for a common ground. Don't kludge it up worse with wyes.
  15. Half of original sale price. It is a complete home theater system and these might still be sold on Klipsch.com
  16. I do think 2.1mm (12 American Wire Gauge) wire will be enough. What amps and preamp are you using? Some people once thought long, especially balanced (3 wire microphone cables) and short speaker wires were the ultimate. Can you put your power amps on or behind your La Scala's and run long cables to them? I use 3 pair twisted, then braided CAT 5e cables for speaker wire. They amount to about 2.3mm (10.5 AWG) wire. The insulation and all that braiding results in a low resistance, capacitance and inductance speaker cable. They are about 5 meters long. I could not hear a difference between old 12 AWG Monster cable and my homemade wires. But they look good! I also failed a double-blind test at Klipsch HQ in Indy with similar cables many years ago. Klipsch said their braided CAT 5 was -3 dB at 300 kHz! My bottom line is that when the resistance is low enough and inductance and capacitance are not significant, you have a good speaker cable. Buy a large diameter stranded wire and don't worry.
  17. LOL! I'm sorry I missed Sey's last post. The 4uF cap is correct since the Model H has a K-1000 squawker horn and needs a higher crossover point. I have one of those around somewhere.
  18. I think they are a flawed design, because the size of the baffle limits the largest wavelength they can reproduce. Then, you get into the Blose reflected sound "stuff", stealing focus. Maggie's have a certain sound about them, but bass isn't it. Better to use the rear wave/pressure to augment low bass output.

    NC Estate Sale

    Looks like 1980 HBRs, with original boxes. https://www.estatesales.net/NC/Brevard/28712/3948795
  20. Those are pre-1979 Belle Klipsch components. Very sad the cabinets are not there.

    You are better off with an unmolested pair. If you know what you're doing, some upgrades are good and effective. If you upgrade because you read it on the internet, of because a website sell it, you've probably made a mistake.
