  1. 5 hours is nothing. Leave the music playing while you're gone for the day(s). Doesn't have to be loud to get things limbered up, but some of that helps too. You'll have them run in within a week that way. It stands to reason that pliant things become more compliant over some time of use; think boots and baseball mitts as two perfect examples.
  2. What's wrong with all the gear you have already? Looks like it'd be quite satisfying.
  3. Between the speaker and those doors I'm thinking upwards of 400 pounds. What've you got for the floor system under them?
  4. I had the integrated amp like that receiver, though I think mine was 40 Watts a side. Probably the pre/power amp from the receiver below yours. Same vintage, same Twin Power setup. I continually cranked the crap out of it with two sets of speakers, so 4 ohm nominal. You'll be just fine.
  5. No. "Constant Directivity" means that energy at different frequencies throughout the working range stays within the confines of the thrown pattern. In that case the balance between the lower and higher ends of the range is different than if the lower frequencies were allowed to spread our more (as they'd be inclined to do otherwise) and the higher frequencies were allowed to "beam" more (as they'd be inclined to do otherwise). If a driver is not made in such a way as to compensate for that itself then "exterior" means must be employed. If done passively (as being discussed) then one or more combination of further elements are employed to "equalize" (bleed off unwanted spectrum energy) the signal going to the driver. This will be a block of specific-value L/C/R components separate from those of the "crossover filter elements." I see none of that in any of the schematics above based on a cursory glance scrolling up the page.
  6. Caps don't really have "break points." What they have is a decreasing reactance (impedance) as frequency rises. They all follow a curve starting at "infinity" (or thereabouts) at 0 Hz (DC). What one might call the "break point" is the place in the curve for any value of capacitance where the impedance of the cap matches that of the driver itself or as seen through a transformer if there is one (or any other resistance between the cap and driver), thus each consuming half the signal (the cap and whatever makes up the load as seen after the cap).
  7. Of course solid-core doors perform that function rather better than hollow-cores.
  8. A Pentium 100 MHz computer would sit idle 90% of the time serving files. I'd recommend encoding in FLAC instead. (You'll want a computer a bit more current for that particular task.)
  9. I still haven't taken the time to perform critical experimentation. Very little, if any, jumped out at me at first. It'll be interesting to play with but I'll likely leave the extra wire in use just because it's a pain in the *** getting to and snaking them. I won't forget to report any findings but y'all might forget in the mean time.
  10. I'm sure things sound different with them removed. It's got to be a good 25% reduction in "flowable" area with the screens in. Aside from anything else going on (like developed compression) it seems as though at the least the output level of the driver would change, and possibly not evenly so throughout its range. I don't believe it's something I'd mess with.
  11. I'm guessing it will will work as intended, but not exactly so. As the horn kicks in going upwards there'll be less "usable" downward extension than you'd have with a direct radiator so back-loaded.
  12. I lived out in the Rockies for some years after growing up in WI. The scenery is majestic and terrain obviously more or less greater in 3D qualities out there.. I ended up back (slightly different part of midwest) where it doesn't matter what the horizon looks like because it can't be seen for the Hardwood Trees. The eastern mountains are better for their non-high-altitude-desert qualities but there's too many other folks everywhere. The story is that used to be when white man got here a squirrel could start out on the east coast and make it to the Mississippi without ever touching the ground if it so wanted. I've seen in writing that Indiana was 85% forested back then, but the white man handily reversed that figure by the early 1900s. No stereos or such but it must've been great to have seen and lived in its "original" state.
  13. If you had decent connectivity... I'd say try burning an Ubuntu image to a thumb drive and boot the laptop into GNU/Linux off of it. Sure sounds like a driver/O.S. problem to me, and a completely different operating environment would rule it in or out. Either that or some crud in the output Jack is preventing a good "common" connection. And/or for whatever other reason your plug isn't seating fully?
  14. Looked up the Echo Link Amp. Sounded a little promising until I read https://www.wired.co.uk/article/amazon-echo-link-vs-echo-link-amp-review. My NAD C338 works well with the next bigger brother to the Heresy.
  15. You could start with the cabinet stuff and work your way up to the crossovers then maybe any drivers. Take note that any screws into the MDF have a finite number of re-uses. Even taking great care they get looser every time. Just saying that I wouldn't be taking them apart often to work on them, unless the screws I'd be removing were machine threads into t-nuts. I don't know what you're going to find in that respect. The other side of the coin is that if you do everything at once you won't know what to tweak or back off so easily if you find something happened that doesn't suit you. Using increments combined with familiarization will immediately identify the cause of an offending result, if there is one. Nice sentences, by the way 8^)
  16. Just use a little discretion and you should be fine. There shouldn't be any frequency content beyond anything typical to any other source. Where you need to exercise discretion is the volume level.
  17. Boosters for the TV stand legs, looks like.
  18. Isn't it wound, or winding, up already?
  19. Should've said that first, not last. :^)
  20. Admitting you have a problem is the first step to remedying it. Crack open a bottle or can and fix the problem!
  21. The clue is that the extra magnet is outside the magnetic circuit which includes the voice coil.
