Explore why Sound Machine uses graphene and titanium in their high-tech speakers for superior sound quality and performance.

## Key Takeaways

- Graphene is used in the low-frequency drivers for its advanced material properties.
- Titanium is chosen for the HF driver to improve sound clarity and durability.
- The system delivers a wide frequency range and very high sound pressure levels.
- Heavy and powerful amplifiers support the demanding speaker system.
- The design combines cutting-edge materials with traditional high-quality engineering.

## What the video covers

- Sound Machine speakers weigh 250 kg each and feature two 18-inch low-frequency drivers.
- The low-frequency drivers use graphene, a high-tech and expensive material, instead of carbon.
- The high-frequency (HF) driver is made of titanium, enhancing sound quality.
- Additional HF drivers include AMT tweeters and two mid-range drivers.
- The system covers a frequency range from 15 Hz to 40 kHz.
- Sound pressure output reaches 123 dB, indicating very powerful sound.
- Amplification includes multiple amplifiers with power ratings of 500W, 350W, 250W, 150W, 100W, and a total of 1,350W.
- The amplifiers themselves are heavy, with one weighing 150 kg.
- The speaker cables are notably thick and robust, described as resembling mini anaconda snakes.
- The system represents a blend of old-school craftsmanship and modern high-tech materials for total immersion.

Answers

## Questions about this video

Why does Sound Machine use graphene in their speakers?

Sound Machine uses graphene in their low-frequency drivers because it is an extremely high-tech and expensive material that likely enhances performance compared to traditional materials like carbon.

What role does titanium play in the Sound Machine speakers?

Titanium is used in the high-frequency driver to improve sound quality and durability, contributing to the overall clarity of the audio output.

What is the frequency range and sound pressure level of the Sound Machine system?

The system can play frequencies from 15 Hz up to 40 kHz and produces a sound pressure level of 123 dB, indicating powerful and wide-range audio performance.

These people are from Singapore, and they created this very sound machine system. 250 kg in weight per speaker, two insane eighteen-inch low-frequency drivers. And at first I thought it was carbon, but the chief engineer said, "It's graphene." An extremely high-tech

and very expensive material. But that's not all. The HF driver is made of titanium. And this is also HF, but AMT tweeters and two mid-range drivers. And they can play from 15 Hz, and go up to 40 kHz, and do you know what kind of

pressure they output? 123 dB. And all this is powered by a 500W amplifier, a 350W amplifier, 250, 150, 100, and 1,350 W. And here is the amplifier, 150 kg of pure weight, and the modest preamplifiers. And the cables, look at
