Product Description

The Yamaha SUB 100 is designed to connect to select Yamaha MusicCast models, including 2018 model AV Receivers, the BAR 40 Soundbar & the MusicCast 20 & 50 Wireless speakers


Wireless subwoofers are gaining in popularity and the Yamaha SUB 100 offers a great wireless solution within the Yamaha MusicCast ecosystem.

Yamaha’s new MusicCast SUB 100 will connect wirelessly to the current crop of Yamaha AV Receivers to complete a surround set-up. It can also be paired with the MusicCast BAR 40 Soundbar. The subwoofer has an 8-inch driver and benefits from Yamaha’s Advanced (YST Yamaha Active Servo Technology) in a modern piano finish.

But it's not just for the movies. The SUB 100 can also operate with the MusicCast 20s in stereo or with the MusicCast 50, either one or a pair, to create a larger-sounding stereo system.

MusicCast SUB 100 Features

MusicCast CONTROLLER: If you install the dedicated “MusicCast CONTROLLER” app on your smartphone or tablet, you’ll be able to add this unit to a MusicCast network, allowing easy playback (link playback) of low-frequency sound between MusicCast Surround/ Stereo compatible devices and this unit.

Wireless connection allows flexible installation: You’ll be free to place the unit where you like, without the annoyance of making cable connections with external equipment.

Enjoy optimal ultra-low-frequency sound at all times: The low-frequency range (crossover frequency) and volume balance are automatically adjusted as appropriate for the MusicCast Surround/Stereo compatible device that you’re using, ensuring that the sound transitions naturally.

Linked operation for power and volume: The power and volume are linked between this unit and the MusicCast Surround/Stereo compatible units that are paired with it.

Advanced Yamaha Active Servo Technology II: In 1988, Yamaha brought to the marketplace speaker systems utilizing YST (Yamaha Active Servo Technology) to give powerful, high quality bass reproduction. This technique uses a direct connection between the amplifier and speaker, allowing accurate signal transmission and precise speaker control.

As this technology uses speaker units controlled by the negative impedance drive of the amplifier and resonance generated between the speaker cabinet volume and port, it creates more resonant energy (the “air woofer” concept) than the standard bass reflex method. This allows for bass reproduction from much smaller cabinets than was previously possible.

Yamaha’s newly developed Advanced YST II adds many refinements to Yamaha Active Servo Technology, allowing better control of the forces driving the amplifier and speaker. From the amplifier’s point of view, the speaker impedance changes depending on the sound frequency. Yamaha developed a new circuit design combining negative- impedance and constant-current drives, which provides a more stable performance and clear bass reproduction, without any murkiness.

Twisted Flare Port: Today’s bass reflex speakers use a Helmholtz resonator to improve their bass reproduction.

However when reproducing bass that is in the frequency region of this Helmholtz resonator, air moves violently in and out through the port between the interior and exterior of the speaker, sometimes producing noise due to the turbulent air flow at the end of the port.

The port and the cabinet resonate at a frequency that is determined by their dimensions and shape. On the other hand, turbulence in the air flow at the end of the port contains a broad range of frequency components that are not present in the input signal. This noise occurs because the broad range of frequency components includes components that match the resonant frequencies of the port and cabinet, causing strong resonance.

The Twisted Flare Port developed by Yamaha changes the way in which the port widens toward its end, and also adds a “twist” to suppress airflow turbulence at each end of the port and thus prevent noise from occurring.

This substantially reduces the “muddy sound” and “wind noise” that until now have been characteristic of bass reflex speakers, allowing bass to be reproduced clearly.
