YAMAHA YST-SW011 SUB QD-BASS ACTIVE SUBWOOFER EXCELLENT SOUND!

NICE, SUPER CLEAN, SMOKE-FREE, WORKS AND SOUNDS LIKE NEW

This Yammy punches far above its weight/size ; I was very surprised; it is better than many well known sub brands priced $150-$200 used. The bass stays precise, non-boomy regardless of power output.

This Yamaha sub will be tested for a local Ottawa area buyer at the front door with a CD player.

Full audio enjoyment of advanced sound processing formats like Dolby Digital and DTS requires deep, clear bass response. That means you not only need a subwoofer, but a subwoofer capable of handling extremely low frequencies and high power levels. The YSTSW011 is designed to deliver powerful bass to your digital home theatre system.

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.

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.

************************************************************************************* Local buyer much preferred, cash on pickup; yes, I have change if needed; e-transfer is possible, but is unpredictable, it takes 1 min to 30 min waiting to go through; Pickup only on this (fairly large/heavy), no shipping, no deliveries.

I've been collecting vintage stereos for a long time, so trades for old receiver, amplifier, CD player, speakers, turntable in any condition will be considered; That's locals only for trades, Ottawa area; I test trades first.
