I never knew people found that sound scary. To me it meant the beginning of a magical movie experience. We used to crank the surround when it came up. Whole house would shake, it was awesome!

I never knew George was so instrumental on modernizing sound systems! We don't give the guy enough credit.

7:05 this part was the reason why I am scared of THX Logos, he literally jumpscares you

I love the THX deep note sound. It was an attention grabber. The theatre could be bustling with noise then the sound hits as the lights dim and silence would fall and it was glorious.

The last time they were relevant was the THX reference in the movie "Over the Hedge" I love that movie

Lucas and his team were truly pioneers of modern cinema. The first sound update to theaters since the 1940’s. Crazy.

3:17 OMG the REVENGE of the Jedi shirts were a real thing!!!

The THX logo ironically never really "scared" me as a kid, but I was always caught off guard from how disproportionately loud it was compared to almost everything else on the VHS tapes and DVD's I'd see it on. It's because of this that I still LMAO at that one time Tiny Toon Adventures parodied THX with the "T.H.U.D" sound system, it's slogan being "The audience is now deaf". XD

George Lucas famously said: "Sound is 50% of the moviegoing experience". Sadly we no longer have THX in theaters.

The THX sound never scared me as a kid, in fact for me it got me pumped up to watch the movie! I just loved how epic and grand it sounded.

0:44 THX means thanks. You're welcome

I always loved the Parody of it on the Simpsons way back, where it sends a shockwave through the theatre and people's eyeglasses are shattering and stuff. Then afterwards everyone cheers and hollers like its the best thing they ever experienced lol

Fun fact: THX was known for refusing to certify the vast majority of LCD TVs on the market because the vast majority of LCD TVs of the era had issues with greyish blacks, poor viewing angles, and low contrast (masked by tons of "processing" that destroyed the details in the shadows and brights), despite the obvious market pressures to certify more LCD TVs. Which brings the question: Now that they are owned by Razer, are their standards for TVs still that high?

The Simpsons did the best representation of the THX note sound in theatres with the glasses breaking, teeth shattering, and a head exploding.

How can somebody find this sound scary, It was so badass. It never disappoints. Just like the playstation 1 intro

I don’t ever recall getting to hear the deep note in theatres, but I did get to hear it a lot on car trips when my siblings and I would watch movies to pass the time. An iconic sound
