WHAT IS THE ADVANCED YST FEATURE IN YAMAHA’S SYSTEMS?

Yamaha is marked as one of the most reliable brands for audio gear. Their commitment to quality and innovation shines through in their systems. Musicians and music enthusiasts worldwide rely on them to provide gear worth having. And so with decades of experience behind them, Yamaha packs their equipment with a wide range of features to improve sound quality.

One of these features was brought to the marketplace in 1998 with speakers utilizing YST (Yamaha Active Servo Technology). If you’ve gotten any of their subwoofers since then, you’ve probably seen Advanced YST stamped onto the front panel or have noticed “YST” in the model number. But what exactly is YST? And why does it matter?

WHAT IS ADVANCED YST?

Advanced YST stands for Advanced Yamaha Active Servo Technology. It uses a direct connection between the amp and the speaker, allowing accurate signal transmission and more exact speaker control. It creates more resonant energy than the standard bass reflex method because of the resonance generated between the speaker cabinet volume and port.

So this technology is used to cancel out impedance for a perfectly linear motion, resulting in higher sound pressure levels and outstanding overall performance.

WHAT IS ADVANCED YST II?

But wait - Yamaha stepped it up! In systems like their YST-SW515 and YST-SW225, they use Advanced YST II. This more recently developed technology refined their Yamaha Active Servo Technology to allow for better control of the driving forces behind the amp and speakers. In Advanced YST II, an Advanced Negative Impedance Converter lets the speaker cone to be driven with even tighter control, which provides a more stable and accurate low range response. This results in less murky bass reproduction, higher sound pressure levels, and a more natural and energetic sound.

SO WHY DOES IT MATTER?

Now you know the technology behind it all. Great! But…why does it matter? What does this technology actually mean for us?

Well, it all comes down to the bass: because of the way it’s set up, Advanced YST gives a powerful, high-quality bass reproduction. This super-bass sound adds a more realistic, theater effect to your home stereo system. And who doesn’t want that?

This also means better bass from much smaller cabinets than what was previously possible. Most of Yamaha’s YST subwoofers are more compact than your typical sub. Rather than a big block of speaker taking up half your floor space, many are designed to sit horizontally or to be small enough to fit under a couch. 

AN EXEMPLARY EXAMPLE: YST-FSW050

If you’re still wondering what this technology looks like practically, then here’s an excellent example: the Yamaha YST-FSW050.

This system gives you the wonderful punch of bass you crave from any subwoofer. It’s a sleek, compact sub designed to take up less floor space than your standard sub: it can fit on a shelf, in a TV rack, or atop a table. You can even place the unit vertically! And its Advanced YST II technology means it has that theater-in-the-home effect we were talking about earlier.

SUMMARY

Advanced Yamaha Active Servo Technology (Advanced YST) is a unique system where the speaker and amplifier work together to cancel out impedance so the speaker unit has perfectly linear motion. This helps to ensure the highest levels of sound pressure and reduces bass distortion. But really, all of this just means that you get the home theater thrills you want from your stereo system.

Thanks for reading until the end! Have a fantastic day.
