  1. You were writing about cost, not wire size. I generally use 12 ga. but on the tweeter (tri-amped) I use #14. The audible difference between 12 ga. stranded copper wires with the same number of individual conductors making up the strands is negligible, IMO, regardless of cost. If anyone is considering purchasing $1000+ on speaker wires, know this - you would achieve better results spending $50 on the wires and $950 on room treatments. The audible difference is not even close.
  2. Because that is all that is necessary? If one looked inside an electronic device, one would find numerous parts that cost 0nly 10-25 cents each. Because that's all that is necessary to do the job.
  3. -.- .-.. .. .--. … -.-. ….
  4. Probably a Zobel circuit inside the little black box. A Zobel could help, maybe.
  5. I doubt anyone would hear anything at 96 kHz. If anything could be heard it wouldn't be musical.
  6. The reactance value is not simply added to resistance. It is a vector summation of the two values, with the reactance values on the Y axis and the resistance on the X axis. Therefore, the impedance cannot fall below the resistance value.
  7. I saw that each video was over 1 hour so I didn't waste any time watching any of them. I suspect this guy couldn't set up a snowball stand much less set up a high performance audio system. 😬
  8. Any cable will only degrade the signal it carries. The shorter the cable, the less damage it will cause. Ripoff cable companies' salesmen have told me that using longer expensive cables will make things sound better...
  9. You could also mount and solder the under chassis components to an octal socket and wire the caps to an octal plug, making changing caps a plug in operation. Could also do this on new builds.
  10. Basically, "bi-amping" without some sort of active crossover only allows one to adjust high and low levels independently. People who do this usually want to jack up the bass, it seems.
  11. Running two amps through the passive crossover is known as "fool's biamping". It's far better to split the signal before the amps, preferably with a digital loudspeaker processor.
  12. One watt per channel into a pair of Khorns in my room will yield 100 dB SPL "C" weighting slow response at the listening position.
  13. Insulated jumper combs are neater than wire jumpers: https://www.google.com/search?q=jumper+combs&tbm=isch&source=iu&ictx=1&fir=oC1OpIuE9PWQ-M%3A%2CMhjxi_OopDOVCM%2C_&vet=1&usg=AI4_-kT5SwnLFGq7-b4an1utXY9HIea_eA&sa=X&ved=2ahUKEwjOmdzZo43oAhVKYKwKHVuiBU4Q9QEwAHoECAoQFg#imgrc=oC1OpIuE9PWQ-M:
  14. That's what I think. Didn't Al test this out here years ago? It seems that about every year or so someone comes up with this question. The circuitry is 2 filters in series, not a simple series capacitive circuit.
  15. This type of crossover is called "improved three-way" by Don Davis. In addition to increasing the order of the tweeter network it is "a true constant resistance network". Also, "The summed frequency response is ideal in that the sum of the transfer functions is identically equal to one. The summed power response is also identically equal to one". Quotes are from Sound System Engineering by Davis and Petronis, third edition, page 299.
  16. You may be able to put 20 Hz into the speaker, but what you are likely hearing is harmonic distortion.
  17. The picture shown is not for a balanced output to a single ended input. It is for a single ended output to a balanced input. XLRM connectors plug into balanced inputs. If the equipment uses servo balanced outputs pin 3 can be grounded without equipment damage, or left unconnected. Behringer and DBX, among others, use servo balanced outputs. Outputs that are not servo balanced may need a resistor on pin 3 to ground, with the signal connected to pin 2.
  18. Most sound reinforcement speaker systems are tested outdoors at 10 meters with a 10 watt input signal. This is exactly equal to 1 watt at 1 meter. Loudspeakers tested in a chamber could be at I meter or longer, with input power adjusted so that results are equivalent to the 1 watt at 1 meter spec.
  19. They came. They saw. They got beat by LSU!!!!!!!!!!!!!!!!!!!!!
  20. I would hang drapes over the window and do what Gary said wrt the area rug and macrames or something soft on the walls.
  21. Weigh one and see what it actually is?
  22. High pass filters are difficult ($$$) to implement in a passive crossover. An active HP filter, or "rumble filter" for vinyl, is necessary for ported cabinets.
  23. I mean, how good is OSU? I figure they have a rather inept coaching staff - they had Joe Burrow and let him get away from them.😁 They let the likely Heisman winner go to an SEC school that is now top seed in the CFB playoffs, and OSU might have to face their former player. Joe would really like that to happen, but I think Clemson is going to win against OSU on December 28, setting up an LSU versus Clemson Championship game.
  24. Do you have cable plugged into the tuner, or an antenna?
