The Yamaha NS-SW310 Produces Awesome Deep Bass


Natural sound
With more and more music and movie sources becoming high definition, such as digital broadcasting and Blu-ray Discs, your speakers have to keep pace. They have to be able to clearly reproduce the extra level of detail, clarity and depth that these sources provide. The NS-SW310 subwoofer uses new materials and precision- designed cabinets to ensure the best possible sound from HD sources. These subwoofers also include Advanced YST II for deep bass.

Advanced YST II for Awesome Deep Bass
Yamaha's newly developed Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant current principles to drive the speaker cone with even tighter control than before. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound pressure levels, for more natural and energetic bass reproduction.

PWM Digital Drive High Efficiency Amplifier
The NS-SW310 delivers high power outputs at deep bass levels, with excellent stability and low power consumption, even with its compact cabinet. This is made possible by a highly efficient power amplifier. The power amplifier achieves superior conversion efficiency by supplying maximum power (minimizing power loss) from the power transistors according to the output level. It delivers stable power output with high efficiency while minimizing power consumption and heat production. It does not require an output filter coil, resulting in extremely low noise and distortion. High speed transient response is also excellent.

Linear Port
Advanced YST II produces rich bass sound, and the addition of a Linear Port helps to ensure smooth bass response, while minimizing extraneous noise.

Color Name: Black Verified Purchase
I bought this subwoofer as part of a system to improve the sound of my Panasonic flat-screen plasma tv.I was not satisfied with the sound of the current batch of sound bars on the market.I matched it with a pair of Sony SS-B1000 small bookshelf speakers.I am very pleased with the resulting audio quality.This unit does a great job of reproducing the bottom end of the audio spectrum,and it is small enough to fit on the shelf of a tv stand when laid on its long side.Like the previous reviewer I too wish it had a better way of connecting the speaker leads but this was not a deal-breaker.If you have limited space that won't fit a conventional square sub You should check this one out.It might suit your needs.

Quality Yamaha product. Perfect for use behind furniture which is where I placed it. Fills the livingroom with powerful low end and is tuned to match room acoustics thanks to my Yamaha Aventage receiver with YPAO. Glad I bought it. Spacesaving, and worth it.

Sorry, but I got so carried away talking about the good stuff that I forgot to mention the one fault I have with the Yamaha NS-SW310 subwoofer, and that is the rather small and cheap spring loaded speaker terminals. This is the reason I gave this unit 4 stars instead of 5 for features. Both my receiver and my bookshelf speakers have proper binding posts and I think at $400 Yamaha could have done the same. All in all, though I still like this little sub a lot and would still recommend it.

This item found as USED, but $100 off list price. If you need a tall tower subwoofer , you can hide this is for you! I agree with another reviewer, yamaha could have used Banana plug hi-level speaker inputs, but ok as is. Never had issues with spring loaded before. The ease of auto-on, is a nice feature to be green!

So far sounds great. Have yet to hook up to surround sound, or use it for movies, to hear the booms!

You will not be disappointed with this product. Many features for flawless use in a surround system.
