Powered speakers show audiophiles are confused

@kota1 Maybe you can help me here about a question from the amazing sound system in the YouTube video. Wave guide high frequency, in my day was popular until they realized that near field deflection is another word for phase problems, how can such a high end room use a proven physics problem? Wave guide mid frequency speakers in that room are guilty of the same sin. A bass speaker like the one in the video make so much more sense than a huge horn that must deflect the wave at some point in the horn. Is near field reflections / deflections not a thing anymore?

There are home theater guys that do custom builds with the type of horn speakers they have in movie theaters and multiple monster subs of the type @phusis describes. The goal is not to "hear" it but to get kicked in the chest with SPL’s when watching or listening at reference levels. In terms of reflections/deflections I am not familiar with the Trinnov optimizer. When the guy was reviewing the Dante related gear in the rack a lot of it was DSP related. The Trinnov guy said how his team had to create a new set of filters to optimize the bass in that room as even the microphones needed had to be customized because they could not handle that level of bass. The room treatments are hidden behind the acoustically transparent covering on the walls.

When they talked about playing the Metallica concert at 120DB with no distortion I had to smile. I have that same disc in my collection in both versions, including the 3D. I can’t imagine 120DB levels for that entire show. But now that I saw that sub I have already started planning on getting two more to bring my system up to four. This is from a review of my Sunfire sub:

 But the main thing - the manufacturer claims that at such a scale that kid on the coveted 20 Hz provides a sound pressure level of 110 dB, which looks absolutely fantastic. Surprising as indicators and power - 2.7 kW (!) output peak and 600 watts continuous power consumption of the network.

If I can get up to 110DB in my much smaller room it will be good enough for me.

I use the same approach they used for the front channels, mirroring the front 3 channels above and below the screen (they used 5 instead of 3 because of the width of the screen). Having a top center channel just locks dialog in the center of the screen during a movie and anchors music mixes/upmixes as well.

That's not the question @donavabdear asked.
