  1. Do you have cable plugged into the tuner, or an antenna?
  2. Having a well balanced subwoofer system does seem to result in improvements throughout a speakers frequency range.
  3. Only $42,250.00 used!!!!! I can guarantee that anyone dumb enough to pay that is going to be too dumb to "adjust" the controls properly.
  4. You might want to look into tapped horns. They have elements of TL and horns, and are compact relative to exponential horns of the same low frequency cutoff.
  5. DSP loudspeaker processors all have EQ capability in addition to crossover functions.
  6. He seems to be using 57 1/8 inches of solder per joint, for the best sound. πŸ™„
  7. The only thing I know about black tie-wraps, performance wise, is that they do not degrade in sunlight like the "clear" ones do. All of the other information about different colors is bullshit.
  8. Testing a Khorn outside on a driveway? ROFLMAO That's exactly what I would do if I wanted to manipulate the results in order to make that speaker look bad. But I guess the dummy wanted to be "fair" because that's how he "measures" all of the speakers he tests. The Khorn is designed to be used in 1/8 space, i.e. in or very near a corner. The Stereophile tests were run in 1/2 space, i.e. in an open area with the Khorn sitting on a concrete driveway. No Bueno. The way I understand the enclosed backs on the AK6 is that the speaker doesn't need to be pushed tightly into the corner of the room, and can be adjusted to aim toward the listening position. The one thing I do agree with is that using a DSP and triamping the Khorn improves it's performance.
  9. I was referring to the KT88 build from March of this year. Well, I have used a Weller WCTPC 60 watt production soldering station with an 800 degree chisel tip to solder 12 gage wire to the inside of a 1/2 inch schedule 40 stainless steel pipe. Previously that job had been done using a propane torch, so... I'm pretty sure that soldering station could solder any wire you have used in amplifier builds. You brag about using MIL spec wire, yet you do not use MIL spec tools and standards to solder those wires in your builds. Got itπŸ™„
  10. I find that to be an incredible statement considering the poor quality soldering I see in your builds. The lousy solder joints likely cause far more audible degradation than the few milliohms difference between wire gages do. I see you use a soldering gun for your projects. So did I when I was a high school student many years ago. I have since learned that a controlled temperature soldering iron with interchangeable tips yield the best results; Temperature controlled soldering equipment is required by NASA, and soldering guns are specifically prohibited.
  11. The importance of wires and cables increases as cable length and the frequencies that the wiring carries increases. Audio frequencies are low relative to UHF, and wiring is less critical for audio, especially home audio, where loudspeakers are usually located less than 25 feet from the amplifiers that drive them. Commercial installations that may use hundreds of feet of wire are a different matter. If an audio enthusiast is using inefficient loudspeakers that require a lot of power it may be important to pay attention to wire size and to the temperature rating of the wire's insulation. Otherwise, a general recommendation of 16 gage or larger is sufficient and it doesn't hurt a thing to go larger. As far as uber expensive wires, I consider them to be a waste of money as I have never heard any difference between them and much less expensive wires. I would never buy any component without listening to them first. I can easily discern a difference between amplifiers, preamps, speakers, phono cartridges, CD players, and DACs but not between wires.YMMV
  12. The volume knob on the preamp controls the signal going to the amplifier, so no concerns about overdriving the amp.
  13. They are copies of the QSC RMX amplifiers: https://www.qsc.com/resource-files/productresources/amp/discontinued/rmx/q_amp_rmx_series_specs.pdf
  14. An electrical supply house or this on-line dealer has what you need: https://www.digikey.com/products/en/cables-wires-management/cable-ties-holders-and-mountings/488/page/2
