  1. Good idea. Cut the felt to size and set the Cornwalls on top. Carpet scraps are also good.
  2. Al K has upgrades for Klipschhorns and other Klipsch products that include wooden mid horns: http://www.alkeng.com/
  3. So let me get this straight - hooking speaker cables to the antenna input of a tuner is a good indicator of it's audio quality as speaker wire? I have read where noise was getting into an audio system, and it turned out to be a nearby traffic signal controller. The speaker wires were picking up the noise, which was amplified through the amp's feedback circuit. Their solution for the problem was to use coaxial cable for speaker cable, with the shield connected to common. Please note that it was a combination of a nearby EMF producing device, the speaker wire, and the amplifier's circuitry that caused that audible issue. If an EMI issue exists, shielding all wiring may be necessary. Some audio equipment is better at rejecting noise than other equipment, so YMMV.
  4. I use the gray pads for aluminum, red for stainless steel.
  5. Scotchbrite pads will do what you want, and will restore the original appearance.
  6. Having 24 bits is most useful in multitrack studios where mixing a bunch of channels together raises the mixdown track's noise floor. 16 bits is more than sufficient for home use, if the mastering is carefully done.
  7. Jimi Hendrix in 1968 during his 50 shows in 50 days tour. Plus the rest... Beck, Clapton, BB King, Steve Vai, Angus Young, etc., etc.
  8. Running Class B as an AM modulator, 20 watts input drive.
  9. Great specs too... 3000 volt plate voltage, ~400 watt dissipation. They must light up like an incandescent bulb.😲
  10. An observable effect from spacing the mid and high frequency section away from the bass bin is lobing of the polar response. This reduces energy from the dominant lobe and puts the energy into the side lobes. The side lobes then hit the walls of the room the speakers are in, causing early reflections which "smear" the sound due to different arrival times (comb filtering).
  11. Used McIntosh SS gear is within your budget, and will sound great with any Klipsch speaker. Recently, matching Mac gear that included power amp, preamp and tuner was sold for under $2K in my area.
  12. 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.
  13. 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.
  14. -.- .-.. .. .--. … -.-. ….
  15. Probably a Zobel circuit inside the little black box. A Zobel could help, maybe.
  16. I doubt anyone would hear anything at 96 kHz. If anything could be heard it wouldn't be musical.
  17. 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.
  18. 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. 😬
  19. 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...
  20. 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.
  21. 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.
  22. 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.
