The Yamaha YST-SW1500 12-inch subwoofer is powered by an extremely efficient built-in 1,000-watt amplifier, and, with its advanced YST Active Servo Technology for expanded base response, it delivers the bottom-heavy tones music fans expect. YST is a complementary amplifier/speaker system that utilizes negative impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass tones.Built-in 1,000-watt amplifier delivers efficient power

  • QD-Bass (Quatre Dispersion Bass) technology
  • Advanced YST (Yamaha Active Servo Technology)
  • Remote control unit
  • Extremely efficient amplifier with 1,000 Watt power and highly efficient power supply technology
  • 30cm (12”) extra-long stroke driver with Dual-Bias System
  • 6Hz ultra low frequency reproduction
  • BASS (Bass Action Selection System)
  • LFE (Low Frequency Effect) input
  • HPF (High Pass Filter) output
  • Low (1W) standby power consumption

The subwoofer is A/V ready and features magnetic shielding, which lets you place the speaker on a TV or video monitor without degrading the picture. Other features include a 16 to 200 Hz frequency response, line level and speaker level connections, an auto power on/off, a high pass output for music listening, an LFE input, a high cut slope (-24 dB/octave), a volume control, a phase normal/reverse switch, and a BASS (Bass Action Selector Switch). The subwoofer contains a 12-inch long stroke with dual bias cone driver, and is housed in a 1-inch-thick real wood cabinet.

The YST-SW1500 uses Yamaha’s Advanced YST as well as brand new technologies such as QD-Bass to deliver exceptionally crisp, clean, powerful bass all the way down to 16Hz. The YST-SW1500 has an extremely efficient, high-power amplifier built in, and uses an extra-long stroke, drivers that provide  outstanding power with low distortion. The YST-SW1500 also introduces a Dual-Bias system with a 100mm (4") diameter voice coil for the ultimate in power and performance.

Subwoofers for the Digital Era

Now that audio and video have largely moved to digital formats, the demands on speaker systems are greater than ever. The latest home theater systems, in particular, not only use high-performance DVD players, but also exploit the merits of advanced sound processing formats like Dolby Digital and DTS Digital Surround.  full audio enjoyment of these digital sources requires deep, clear bass response. This is especially true with 5.1 (6.1)-channel sound, because the sixth channel is dedicated to the bass frequencies. That means you not only need a subwoofer, but a subwoofer capable of handling extremely low frequencies and high power  levels, as well as accurately reproducing the high quality digital sound.

QD-Bass Technology

QD-Bass (Quatre Dispersion Bass) technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates (not used in competitors’ down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance  between sound waves reflected from the floor and the unit. Also, most other systems use circular cones, but by radiating in four directions to avoid the legs of the cabinet, QD-Bass reduces turbulence caused by reflection from the legs. Changing the height of the square pyramid varies the acoustic load, permitting  relatively simple high-cut adjustment and improved bandpass properties.

The QD-Bass system provides extraordinary power and smooth frequency response from an extremely compact unit. It also allows greater freedom of placement, since the sound radiates with equal effectiveness in all directions.

Advanced YST

Yamaha’s patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. Advanced YST is the ideal method of combining amplifiers and speakers for maximum performance. This system’s advanced negative impedance converters intelligently adjust the negative impedance generation as the speaker moves, creating a hard, rigid cone that prevents deep resonant waves from leaking out of the speaker cone. This means the full power of the waves is forced out through the air port, resulting in clear, powerful bass.

Yamaha Factory Refurbished

Buying a Yamaha Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with original accessories included. When you consider that a factory-renewed Yamaha product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Yamaha repair center (you can look-up locations online here or call 714-522-9888)

Yamaha, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Yamaha certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Yamaha Factory Refurbished" product.

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
