  2. Once you get old enough, you'll find that you remember fifty years ago better than you remember fifty minutes ago. 🙁
  3. When I was a kid, gliders were 10¢ and Sleek Streaks were 25¢. How much did this one cost?

    A local vendor had one in concrete. About the same size and countenance as yours. They wanted $1400 for it, plus delivery. I passed.
  6. Within the past six months or so. My most recent attempt, at least for audio, was with the Raspberry Pi. I gave up in frustration and returned to ASIO. I've used *NIX variants, on and off, since about 1990. It's come a long way, but for audio it remains a nightmarish path to success, if you're trying to do something that doesn't fit into a nice ALSA ready-made wrapper.
  7. I didn't say that it was impossible. I just said that it was abominable. Unfortunately there are few alternatives.
  8. I have found Linux to be abominable for audio. YMMV.
  9. https://stason.org/TULARC/entertainment/audio/general/12-24-What-is-the-best-stuff-to-fill-a-speaker-cabinet-wit.html I used Fiberloft Mountain Mist in my latest project. It only cost $15 for 2 lbs, which was just right for 3.8 cubic feet. It was worth it.
  10. Mount the woofer in the enclosure and measure its impedance at all frequencies. Peaks in the impedance represent resonances. Resonances (other than that of the woofer itself) come from standing waves.
  11. You have to think in terms of fractions of a wavelength. One-eighth of an inch is negligible when the wavelength is 32' (35 Hz), but it's very significant when the wavelength is 3/4" (18 kHz). Unfortunately we don't get to operate at just one wavelength, so standing waves are almost certain to occur somewhere in the frequency range. We can take steps to reduce them, such as non-parallel surfaces, and dimensions that are not integer ratios, but we can't eliminate them entirely. I recently built a golden ratio enclosure (width:depth:height in ratios of 0.618:1.000:1.618). The box is heavy and strong and well-damped internally, yet an impedance sweep still shows a slight anomaly exactly where a half-wavelength equals the major diagonal dimension. Its amplitude is negligible, but it's still there.
  12. Different context entirely. I'm a few miles away from the guy who's selling the EV horns and drivers. I'm nowhere near Atlanta.
  13. If the person who buys these will be in Hope next week, I could bring them with me. The seller apparently lives just a few miles away from me.
