  1. Sparty has fugly uniforms, Maybe such colors appeal to Millennials, but not to this old fart.
  2. At this rate Harbaugh will need his legacy connection to get a coaching job at Western Kentucky. #7 Hudson, a senior, lined up offside. C’mon man!
  3. Penalties and turnovers are keeping Army in the game. I expect the second half to be better for Wolverines.
  4. Watching Michigan vs Army with no sound while doing NordicTrak and listening to Blues Breakers John Mayall With Eric Clapton. Neither team can hang onto the ball, With 2:51 to go in 1st half: ARMY. 14 M. 7 GO ARMY!
  5. Perhaps the word order in the subject could be reversed. Your hearing is only as good as your ears. At 70, my high frequency hearing is severely limited above 6kHz. Nevertheless, I still enjoy the treble content of music, the cymbals in Take Five for example. When playing test tones through my DIY Super Heresys and four DIY tapped horn subs, I can hear content at 25Hz, more important, I can feel the bass. My best IEMS or cans can’t replicate the bass pressure experienced in my small listening space.
  6. EDIT 9/7/19 @ 08:47 EDT I see this photo was posted earlier. It’s comforting to see hat PWK’s lab was no neater than my workspace. @pzannucci noticed the braces in the attached photo @HDBRbuilder posted in the thread about the new H4. Clearly PWK was aware of the sidewall resonance issue and braces as a possible solution. Notice they are not vertically centered.
  7. Nice catch. Notice too they are not centered vertically in the opening, which was a topic debated recently.
  8. Part of the rationalization for the purchase was the balance in my PayPal account after selling the electronics that came with the La Scalas @Escher purchased. Somehow that money seems like audio hobby money, rather than real money. After listening to Clapton Unplugged this evening, I’m not sure how much room for improvement there is. As MenloBob said, it’s only $100. and PayPal “play money” at that.
  9. Anyone have any experience with this thing found on page 9 of the Parts Express catalog SS Vol. 11? For $129 I might get one to build as a gift for the Millenial kids. Better yet, I give them the kit and let them build it.
  10. I wasn't suggesting that the cast frame itself increased excursion. I identified the HIPs' woofers as EV cast frame woofers to do just that, to identify them. I assume they are able to handle the excursions allowed in that ported enclosure, as Klipsch included them in the HIP.
  11. I assume the EV cast frame woofers in my HIPs can handle the porting, as can (I hope) the Eminence Delta Pro 12A woofers in my ported DIY Super Heresys,
  12. Okay, I acted on impulse and ordered a miniDSP 2 x 4 Balanced Kit to give it a try. As MenloBob said above, I can always sell it, or pay it forward to a forum member. I figure I should at least be able to get an idea whether there is a real delay problem with the subs. It may be I’m trying to solve an issue that isn’t really an issue. If it results in an improvement, I can consider a better unit.
  13. This is all becoming very confusing. As I understand it, Chris @Chris A recommends miniDSP HD over non-HD. The 2 x 4 HD is not balanced but could be balanced adding Regurgitators. The 4 x 10 HD can be balanced without Regurgitators. Apparently, the 4 x 10 HD would allow setting crossover points to the tweeters, squawkers, and woofers in the Super Heresys, as well as the cross to the subs. Delay could be set as to each driver also. Am I understanding this correctly? The 2 x 4 Balanced Kit is not recommended because of the limitations of the non-HD configuration. Correct Chris? For reasons previously stated, I’m committed to balanced. Based upon my understanding as expressed above, it seems my choices are: 1. Skip the whole thing and live with subwoofers delayed; 2. Get miniDSP Balanced Kit (not HD) to delay Supers to align with subs; 3. Get miniDSP 2 x 4 HD plus Regurgitators to get balanced; 4. Get miniDSP 4 x 10 HD to provide max flexibility balanced; or 5. Get Xilica at unknown cost and unknown as to balanced. Is any current lag in subwoofer output real, and, if so, is it worth the effort and expense to address it?
  14. My Sennheiser HD 280 PRO headphones play well with the Pono in single ended mode, and even better in balanced mode. Pono in balanced is sweet sounding.
  15. Does the above voltage output info bode well for using a MiniDsp, or not?
  16. I was able to find some info regarding the Pono's output. The following is excerpted from an article in Stereophile. "Perhaps the best way to characterize the Pono player," I concluded in May, "is to say that for $399, you get a D/A processor almost as good as Ayre Acoustics' QB-9 ($3250), with a 128GB hi-rez media player thrown in for free." The benefit of balanced operation is twofold. First, because the PonoPlayer must operate from a 3.7V lithium-ion battery, the maximum unbalanced output voltage is restricted to 1V. (With a 1kHz tone at 0dBFS and the Pono's volume control set to its maximum, I measured slightly less than this from the headphone jack: 961.3mV.) Although in balanced mode each of the signal-phase outputs is limited to the same 1V, because they're in opposite polarity to each other—as the cold phase swings negative, the hot phase swings positive—the maximum output voltage is doubled; ie, increased by 6dB. This will, in theory, lower the noise floor by 3dB for the same playback level as in conventional mode. Second, any noise that is common to both signal phases, as well as even-order harmonic distortion, will be canceled with balanced operation. The full review can be seen at: https://www.stereophile.com/content/pono-ponoplayer-portable-music-player-balanced-mode
  17. This will demonstrate my ignorance. Might it be possible to use multiple dsp units to maintain balanced, that is, to have a + & - for each channel without a common ground? It’s starting to sound very complicated, but I do want to preserve balanced. I do not want to insert something between the preamp (Pono) and the amp that will degrade the midrange and treble.
  18. I could find the max output of the Pono player balanced outputs, but I doubt it’s very high. ”2 Vrms which is only about +8dBu.” Is that Russian?
  19. Now I see you edited your post after I quoted it. Thanks @Chris A

    Jokes?

    A guy is telling a coworker that, as he drove by a prison, he saw a midget escaping by climbing down the fence. The coworker told him he should not use the term midget, as it’s a little condescending.
