  1. He needs to turn that tweeter 90 degrees as it's dispersing up and down, not side to side.
  2. I don't think it was intended to be powered by a phone feeding it signal. Plug a USB cable from a wall charger into the port marked with the wall plug maybe? That was a guess after looking at a photo of the back. Downloaded the manual and that's what it says to do...
  3. Price is fair. Try to get some imported... Finish is fine, too. They're for listening to more than looking at anyway.
  4. Probably wasn't the L100 in the studios. It'd be 43xx (4311 in this case?). The "L" speakers were perhaps a bit prettier versions of their "real" brethren, which, at least up to some point in the hierarchy had better crossovers, and performed better, than the "L" versions.
  5. Me neither, really. Assuming the "not upstairs" is the basement, it could make sense. If upstairs is the second story, then no.
  6. I once made a 3/4 bath in a basement for a customer. Installed a sanitary pit and put an extra float switch in up high so that if for any reason the pump wasn't working (or if the power went out - it was on city water), a couple of industrial fail-close solenoid valves on the hot/cold lines would ensure the water supply ceased as well. Been a good couple decades now and no such disasters that I've been made aware of.
  7. I've got Forte III. Would love to have some LaScalas, but for the venue there's no way. The Fortes meet all my expectations with plenty of headroom to spare. Don't need subs, either, with them.
  8. [Edit: Wasn't this thread merged with yesterday when I posted this? At any rate, this above is the thread of reference below.] Now that this thread has been merged, the "proprietary" values for different frequency ranges can be found if they hadn't been edited out since. I believe it went something like (paraphrasing) "if you detect (by ear) a small suckout at 2kHz, then you add a 1 uF cap to the bundle." For different frequencies, different values are specified, some of them so small they can't possibly affect anything one hears. I took him to task at the time about that, also asking if he decreased the size of the large ones to compensate. Which is when I first saw him say that target "C values" are really immaterial. At any rate, he's not saying "12 uF spec'd with 11.5 or 12.5 is cool," rather, he might wind up with 15 or 16, hell maybe even 20 by the time he's done, and that's okay because, well, you really should back up now 20 pages or whatever and see for yourself. It's just crazy... I surmise he's conflating value-by-frequency for high-impedance amplifier internals with those for low-impedance crossover networks. The wild part is that it still "works" the same for him in the crossover as in the amp, facts be damned.
  9. How does he like the new unit now that it's broke in? Hahaha! I've gathered that Parasound can be a little on the bright side.
  10. Shout out to @Deang as I believe he's mentioned having that, or a close relative.
  11. Well, there's always the Infinite monkey theorem.
  12. It's merely an acoustic transformer...
  13. I'd take one with me to the local Ace Hardware and rummage through their specialty parts drawers, where you'll find exactly what you need in the exact quantity.
  14. It wasn't CD, but instead a "hi res" download. https://www.highdeftapetransfers.com/products/klipsch-tape-reissues-24bit-192khz
  15. My take on it is that it's primarily for the market in Japan... And with that, as just an excerpt, this thread draws to close. We can no longer use math, physics, or any kind of science whatsoever to prove a point in the face of such declaration.
  16. Isn't that the young lady who built you some furniture a while back?
  17. Last I looked into it they're using diodes to derive the bias from the signal instead of using batteries. As I recall, only the first cap got bias in any event, not the second...
  18. That's always been my understanding and it makes complete sense to me.
  19. Or, maybe they realized that the low ESR of the small cap actually only had effect in unnecessary regions and they were wasting money trying to save it?
  20. I actually didn't, but it seems you've missed mine. In electronic devices local bypass caps at the power feeds is a very real necessity (one factor) and where load impedances are high enough, small-value caps passing signal actually become relevant (second factor). As to what those manufacturers you mentioned are actually doing where and when with bypasses, I plead ignorance as I've never looked over any of their schematics.
  21. Two significant factors there as compared to using them in a loudspeaker crossover, which I'd gathered was the current topic.
  22. I'll try to find those two documents for perusal. Expectation is there will be agreement on my part, but "phase distortions" in my mind implies a relativity throughout the spectrum as opposed to "does the driver initially move whichever way." As to the trying "to justify it with a statement about steady state waveforms" I admit to being at a loss...
  23. Total capacitance is one thing, but adding miniscule-value "bypass" caps as a means of altering the sound quality throughout the passband is utter nonsense. Do the math. Taken individually (which is what will happen), the ultra-small-value caps will only pass appreciable signal well above the audio range of your ears! No way in any known universe that will improve what you can actually hear...
  24. (Hey Dean, have you pulled the trigger on those JBLs yet?)
  25. Point well made and duly noted, though it changes the point of what I'd said little to none. As is "absolute polarity" of a signal...
