I can see it now. A cat get offended in some way, backs up to one of those sonos panels and lets fly. Horrible on so many levels.
Buddy had a cat 45 or 50 years ago who did that to a light socket. When the smoke and stink dissipated, cat was down the road.
Of course, being stubborn and stupid? A repeat the next day iced the cake...
march mentions '10,000$', but I'm thinking if it was over about 1000$, I'm out......

Wow, Paul!
Just look around. How many Non-Informational.....Informational web sites ARE there? All selling the sizzle, not reality.
And while the internet has great POTENTIAL, it is largely unrealized due to profit making and outright scams..
I'm not anti-profit. But am Very Pro Value.
I saw a video I was interested in which made some kind of promise of what I thought would be good information.
They Talked AROUND the point for 15 minutes (of what I later saw was an 80 minute video) before my eyes crossed and I went
somewhere else.
Site starts with a provocative (usually of a sexy nature) photo. ALL are clickbait. Ignore.
If you look at news sites? As you cross from one end of the political spectrum to the other? You can't even tell if they are
talking about the same stuff. The usual suspects rule.
You get the picture.......

My new idea....(not really mine or new) is that we are living in a elaborate computer simulation for the amusement of some really advanced alien species......
After watching Lie after Lie, coming from all directions and heading who knows where? I've come to the conclusion that 'news' no longer exists. It all
serves some opinion pole....to be published.

After watching Lie after Lie, coming from all directions and heading who knows where? I've come to the conclusion that 'news' no longer exists. It all serves some opinion pole....to be published. Yeah my version takes the String Theory (M-Theory) path, relying on the fundamental "Theory of Everything" to solve the puzzle vs some intermediary aliens with computers ... 1 - If the fundamental irreducible entity is the one-dimensional string, which has no mass and takes no space, then an infinite number of them exist at a point (not "in space", just a point) and that is the entire Universe. 2 - What happens then is the strings interact in ways that emulate what we observe as subatomic particles, then atoms, molecules and so on. But there is not ACTUALLY a physical reality because all those entities that we see as physical, are projections of the strings which are NOT physical. 3 - The virtual physical reality is a consequence of infinite random interactions of these virtual entities such that every possible outcome of every interaction - and indeed every timeline, with time itself being virtual - exists simultaneously. 4 - Our virtual existence is on any number of these simultaneous timelines. Nothing is real. Strawberry Fields forever  |

How do you TEST a non-reality....reality?
Is it possible to 'timeline hop'?
The closer timelines are to one another, I'd expect them to be Very Very similar. Differeneces may come down to punctuation or maybe a slightly different alphabet....
Or, as in the case of one SciFi story I read with this as a 'theme', an artist known in both timelines issued a different album. When the character from 'line-A' brought
the album into 'line-B' he was promptly arrested....
A proper theory should make verifieable predictions.....

Let's get things back on topic please. I created this thread to be helpful to those seeking knowledge about subwoofers.
Everyone is welcome to create a thread to discuss other topics they wish.

With all due respect, I know all about subwoofers…… And far more than anything I’ve been reading on this thread to date. Finally, there is some spice here to make it interesting?! (you sure you don’t wanna keep it going just the way it is?) |

I think this is the right place to move this topic since it has migrated from "Latest Purchase" to "Installed and down the rabbit hole". I just put together an LCR 2-Way active crossover with boards and power supply from XKitz. $240 for the electronics including shipping, plus a few bucks for the case, power switch, etc. www.xkitz.com/collections/active-crossovers-and-bi-amplifiers-1/products/linkwitz-riley-2-way-active-crossover-fully-balanced-xover-2bI installed it yesterday and it's basically working. I just have to fine tune the levels of the outputs, then rerun a Dirac calibration.  So what's the point of all this? It's simpler than it looks: - Cross the Fronts to the subs at 50Hz outside of Processor Bass Management, so that the Fronts remain configured as Large, and are used in the system for Bass Management (Center Sub=LFE).
- Cross the CCR Center speaker to two DWMs(Dynamic Woofer Modules) at 200Hz, bi-amping the Center channel. Center is configured Small, and crosses to Bass Management (i.e. Large Fronts) at 40-60Hz (TBD)
- The schematic also shows the Front L/R Hi outputs split to a miniDSP to drive two DWMs which fill in bass cancellations.
- Note that each DWM has two voice coils, so the L/R Hi outputs go to one voice coil in each L/R DWM; and the Lo output of the Center channel goes to the other two voice coils wired in series. DWMs are located next to the Front L/R speakers and slightly forward of the CCR Center which is above the TV.
 I immediately see in the measurements that I seem to have achieved another goal which is to reduce bass distortion by high-passing the Fronts at 50Hz. Although they play down to nearly 30Hz, they don't respond well to dynamic content that low. This configuration protects them and the DWMs from very low frequency transients. The XKitz modules are well-made and the hardest part of assembly was cutting holes in the box. But it's all together and working. I'm not expecting to use the Baffle Step Compensation feature as it's intended for bi-amping drivers in a box, but I will try turning the pots just to see if there is any effect. Otherwise, adjustment is confined to tweaking the separate Hi and Lo output levels with individual 20-turn pots. And here's a measurement of LCR (blue, green, pink) with no overall PEQ or Dirac. All I did was pull the sub 40Hz down in the miniDSP, and did some All Pass filters on the two DWMs for the L/R to eliminate some dips.  |

And the center crosses to Bass Management at 100 (Fronts) and it's way high! I have no clue what's going on. This is just from a single measurement in Dirac to see if it was in the ballpark. I even reinstalled 3.9.7 and used the single measurement again. I'm stumped ... I did everything as we always have ... I need a nap! |

Is there a Level adjustment on the Active XO modules? If so, may need to play with that a bit, trying higher and then lower settings. But first, try just a single mic point run with Dirac first to see if you get a duplicate result which would indicate that you could do some quick Diracs trying various things. |
