Not with per say, but as, yes I have in the past. Easy to do and quite convincing so long as, like Carl mentioned, everything is on center. See the video below of my old arrangement. You can hear the dialogue clearly, even through headphones, as if there is a center channel and that it's all projecting from the TV screen (very pronounced as I rotate the camera away from the TV). The trick is to get your screen positioned where the sound is, ie parked evenly between the pair. It works exceptionally well for the interim, but a legitimate center speaker will yield clearer sound. Particularly when a movie sound track gets very busy.

Where streaming is concerned, I doubt that, based on the nature of its consumers which can be thought of analogous to radio listeners. Where in fact people that tune into FM have no involvement beyond the purchase, or benign use, of a radio receiver. Aside from a tuner, they pay nothing to listen, an the musicians receive nothing. The majority of that material was/is promotional. The whole thing is in reality a gravy train for advertising revenue. People that stream at least have to, at a minimum, burden the cost of the network/technology they're tapping into....yet still have to endure ads. Direct to market is where the real money is at for artist. Ronald Jenkees, Derek Smith (Pretty Lights), and Tipper among several others for example whose careers exploded due to likes of Sound Cloud and Band Camp which cut out almost everything in middle. Once again, so long as the technology is in place.

Congrats and welcome aboard!

Connecting dots that aren't there, really. MCACC software allows the owner to actually see what their system is doing, before and after. Has auto settings sure, but can also accommodate adjustment once the data has been analyzed. All, without requiring the use of a stand-alone computer. Make of it what you will. Some people can run with it. For others, the features gather dust. Anytime DSP is involved, the potential exists for the sound to fall to either extreme, good or bad. It's all in the hands of the operator.

410A here. Between $4-$8 / lb wholesale.

We haven't had A/C since the end of last month. 10 year old evaporator coils rotted out to the point of expelling nearly all the refrigerant for a 3 ton system. Amazing really. Top of the coil pack looks mint (no dust even) whereas the bottom inch looks like it was sitting in battery acid. A brief warm spell into the 90's last month and we noticed the compressor kicking offline due to a pressure fault. Oh well. Techs finally have the replacement part and will be in next week to perform the repair. Thankfully we can "handle" 82 in the house, but I don't like tempting fate with our pantry.

Interested party here. PM sent.

Start with the mechanical fixes (tune-up) first: 1. https://community.klipsch.com/index.php?/topic/143229-my-newold-pair-of-la-scala/&do=findComment&comment=1634397 then 2. https://community.klipsch.com/index.php?/topic/143229-my-newold-pair-of-la-scala/&do=findComment&comment=1634400 which dovetails into my write-up here: 3. https://community.klipsch.com/index.php?/topic/130970-is-it-the-al-3-or-the-squakers/& (suggest reading all my posts and watching the videos near the end)

Yes, I should have gone to bed. At first glance of the video, even the other half was thinking, "Where's this going?" Meanwhile, I'm gushing about the audio. If we can't lean on one another here, we might as well sell all our gear.

Listen. I know my ears can be tricked...like optical illusions of sort, but for the ears instead. Threshold shift, auditory masking, etc. etc. Well-funded research points to the fact that in certain instances our ears, and more notably our perception of sound, can down right deceive us. However..that does little to explain the mechanism of the memory of sound. I can remembers songs, voices, the sounds of animals. The sound of our very world, I'm locked in. All of it. Most I can't seem to forget. I can remember the sound. So here I sit on the fence, because I'm racking myself trying to figure how the hell I managed to establish this link. First I watched this relaxing somewhat clay-mation like video: https://vimeo.com/190063150 I mean, I really watched it....a couple times. Then it struck my ears. I've heard that sound in the background before. I couldn't put my finger directly on it, but I had confidence in the tones I was hearing. It sounded very similar to this familiar tune: https://www.youtube.com/watch?v=miZHa7ZC6Z0 I did a little more exploring, lead me to this clip which is the exact amount of time for the above video: https://www.youtube.com/watch?v=fNIfbdi41ho I haven't heard the startup sound in two decades, yet I was able to pick it out (stretched in-time by 23 fold) from out of no where. This happens all the time too. That's it in a nutshell. This is how my ears hear, and my mind thinks about it. I can't forget the pattern. Anyone else have these kind of experiences?

For 2-Channel: 25x40x(≥15 for point source, 8 for arrays and planars) speakers at ~8 feet out from the 40 foot wall. For multi channel: 40x60x ≥15 center channel at least 8 feet out and 3 feet off center of the 40 foot wall. All dimensions expressed in feet. Poured concrete floor (Spancrete if lofted), filled cinder block or ICF at least 8 feet up, plush carpeting. Heavy drapes at least 8 feet up. Hung acoustic panels.

I've got experience using Growlers, but not the Captivators. Two different animals I know. Build quality was top notch, but haven't seen what any of their custom finishes look like.

Silicone: Silicon:

This is where measurement comes into play. My numbers are of course my speakers + my room + using my geometry. Yours will certainly vary. Sounds like 60 Hz was working well, but neither of us still knows why that really was. I can make educated guesses all day, but in the end they're just that. Note that dialing in 30Hz on the low pass, cuts the sub roughly -12 dB SPL up near 100 Hz, so make sure to go back and dial the gain knob on the sub amp +12 dB from normal. Otherwise, it'll sound rather muted. And I realize some of the 2-ch folks are going to cringe at this, but at some point it takes at least a voltmeter, test tones, and an SPL meter to get a subwoofer to play nice. It's essentially the process of grafting another "speaker" onto your stereo. At a minimum one needs to "see" where the sub and mains are rolling off, how the filters / room affect that, and finally to lock in the phase at crossover. One tell-tale that things are in the ball park is that the system will get very sensitive to any further adjustment. When dialed in correctly, a flip of polarity will equate to a big hole in the bass, or just a little tweak of the gain or freq knob on the sub will push things around a lot.

Yes.

Close. It ends up being 90 Hz. So with filters set at 30Hz and 200 Hz on paper it reads like there'd be a gaping hole. In practice though, it yields nearly flat response employing little to no EQ (very important for preserving transient quality) with the addition of roughly 6dB or more of headroom at unity gain from 40 Hz-125Hz. For SWL, it might help to keep in mind that signal response and cabinet freq response are two separate concepts. They work in tandem, but are fundamentally discrete. The filters condition the signal, which then drives the speakers, etc. etc.

Nope. Analog filters are continuous and infinite. Regardless of slope and cutoff, signal passes until it's buried below the noise floor of the system. The sub is +12 dB SPL from ~30 Hz at 100Hz. The filter is about -12 dB V. It's not exact but the two balance in large part, until the subwoofer rolls off. FWIW - My mains are high passed at 200 Hz. Take a guess where the actual crossover is.

Watched the video. Also checked out the rest of your YT channel. Good stuff! You say the room has horrible acoustics and reference the 18' ceiling. That's not the problem here from what I gather. In fact, the 18' ceiling is the best thing going so far for your bass response. What's the layout of the rest of the room? Technicalities aside, all I hear is the lack of toe-in required in order to maintain tonality. Unless the front wall is wider than 30 feet, firing any of the Klipsch Heritage product straight into an untreated room is going to end up sounding excessively honky.

Setting my low pass to 30 Hz.

This can happen in a couple ways: Mechanical -There was an air leak either inside the cab or at the baffle and the woofer unloaded at some point. -Their performance was "de-rated" by using low frequency EQ or the like. Sliding in +10 dB of signal at say 35 Hz knocks 10 dBW off the overall power handling. A boosted cab that could normally handle 32V broad band will then take only 10V before the woofer self destructs. Thermal The woofers were simply driven at excessive voltage for too long. Sucks, but it happens...much more common in pro sound. K33 or K43 replacements / equivalents are available through Klipsch, Crites, and some other outlets.

Direct radiators (ported or sealed) will always produce higher order content regardless of filter set points. PPLS minimizes that, but can't solve the power response differences. SWL - setting 60 HZ shelves the rising response of the THT. IOW, now you're hearing what a true (acoustic) ~90 Hz crossover sounds like.
