Yamaha YST-SW012 Design

The producers used heavy-duty wood-fiber panels in the device’s design. Inside, surfaces are covered with the high-density material for avoiding the resonance. This feature lowers substantially the noise level and distortions. The sub gives the pure, compact bass and the high power of sounding as a result.

There are special braces inside the Yamaha YST-SW012, that’s why the increased structural strength is provided. In general, the sub is compact and not heavy. It has got the classic design in black, silver or brown with the matte finish. The switch and the adjustment are behind it. That’s not very convenient but not a deal breaker, though. The device is a cube of 11 inches that allows moving it with zero effort.

Yamaha YST-SW012 Features

If you want to receive a deep, powerful bass, not spending a lot of money, pay attention to studying of performances of the very promising model – a front-firing active subwoofer. I hope this Yamaha YST-SW012 review will help deal with the question.

After unpacking the box, you can see a set of 4 non-skid pads for preventing the device from moving by vibrations. It takes a minute to put them at the four subwoofer’s corners. The thing that jumps out at you first is that the driver’s diameter is 7.8 inches. It is quite enough for producing a good tone in anywhere in the room. Then, go with the other YST-SW012 specs.

  • The power of 50 VT is enough to give the bass of a high quality. Low frequencies rend the air, filling sound waves by natural musical force.
  • It operates with the receivers and speakers of the most well-known brands.
  • The dynamic power is a bit low – just 100 VT, so I think it doesn’t fit large spaces.
  • Too limited bandwidth is not a flaw because it is recommended to choose the frequency from 30 Hz to 60 Hz for better sounding.
  • There is no remote control in it that may be a problem for those who used to control technique at a range.
  • The cable in the set is very long (16.4 ft) and can be pulled to any angle of the room.
  • The separate electric power is from the common wall receptacle. There is the button ON\OFF on it.
  • There is no the crossover frequency option, so the decent sound is available only in the vapor with the receiver or sound card, where it is possible to set up this frequency of for the subwoofer.

The sub gives the pure, compact bass and the high power of sounding. Besides, The Standby mode supplies a minimum power consumption and allows decreasing of operating expenses. The high-quality inner components provide the long-term smooth operating of the device.

Yamaha YST-SW012 Performance & Sound quality

The device operates very well in small spaces. The bass is soft and unobtrusive. The nature of its sounding doesn’t flush the sub’s location out. You can feel the bass no matter where you are sitting. The device is easy to control. As opposed to the most low-budgets it does not require modification (insert and enjoy). It’s not futzing out while the downtime at all, so you can keep it switched on.

The company used the Advanced YST tech that allows interacting of dynamics and amplifier for suppressing impedance. As a result, the dynamics get an ideal linear specification. This technology provides the developing of the high-level sound pressure, increasing the common system returning.

The QD-Bass tech rigs a reflective effect from the floor surface and lowers the body resonance that often appears due to such reflections. It is better to place it in the corner. It sounds bad if to locate it in the center of the room or on a short wall.

The problem can appear that the sound level is too low. In this case, you should just replace the sub or locate some large interior subjects like shelves, on the wall surface. Sometimes it is necessary to play a sound source with more bass frequencies.

Polk PSW505 Setup

The YST-SW012 setup starts with connecting the YST’s cable to its input jack to the amplifier’s output one. Then the other audio or/and video components are plugged into the AC outlet.

Before switching the device on you should low the Volume control to 0. Then you can activate the Power (it is one button for all components). The green indicator shows it is done. Connect the Input with the source of the sound and then make the volume as loud as you need. The most rational is to choose the middle position – it is more than enough for one room.

It is important to increase or to low the volume gradually in order to feel and to hear the ideal balance between the sub and other speakers. Regulating the amplifiers’ volume control helps adjust the sound of the whole system.

It is better to set the crossover frequency on the maximum level of 60 Hz, of course, if the receiver allows doing it. It is perfect for watching movies and listening to the concert disk as well. If to put more, walls and the ceiling start jingling. In addition, don’t set the full operational capacity – the device starts “choking”.


The device is indispensable for adding some help in the bass for your existing system. Good bass for the home cinema for the reasonable price is exactly what is required to the wide customer. It is the brightest representative of its price category. It is also the optimum combination of price and quality.

Yamaha YST-SW012 settings are simple, the price is low, and the features are solid – that’s why the device is the perfect variant for small rooms and for everyday use. Before ordering the product, check your existing system – the lack of YST’s inputs could hamper their connection.
