auto on and lows get down to 20 htz

not the best out there but not worst either

this is a decent sub for the price. and very good one for a midfi system. first of all where you put it is critical my best results came from putting it a corner and about two feet out. second i just found out what a big difference a cable can make i switched from monster to bettercables.com and now my sub sounds a lot tighter and less distorted. movies are much more enjoyable well good luck with yours

This is a wonderful earthquaker that also produces exact and harmonic HiFi.In combination with its low price ($400), it's a very good product!

HiFi: Correct adjusted it allmost dissappears, just leaving that magnificent deep tight beat that I really love.
May be a bit boomy in the higher base. Sounds best with the cut off freq. low.

Cinema: Perfect with its high power output. It shakes!
The location is important. Needs a corner for best performance.

Dual voltage (overseas model), adjustments(phase, volume, and crossover), RCA and speaker level inputs.

Power supply, easy to pinpoint sound, crossover is tricky, bass response in lower octave.

I bought this product because I just couldn't go another day without having a subwoofer, and I couldn't afford Velodyne or something comparable. I wish I would have waited. I used the YST-SW150 in my HT setup to compliment my overly bass-shy Infinity RS-525 main speakers. Getting the crossover frequency right for my speakers was a real chore. I ended up letting my Sony receiver handle the crossover frequency, which seemed to work better. Only then the YST-SW150 seemed to really call attention to itself instead of blending in. It could be that the receiver's crossover was too high (no adjustment). I was impressed at how fast the response was to kick drum and fast beats in rock music. It really does pump out some bass for dual 8" speakers. After running some tests with a VU meter and a test tone CD, I determined that the bass rolls off around 30Hz sharply. A 20Hz test tone was virtually inaudible at any volume level. The rumbling that I expected to feel in my chair during movie soundtracks was not there either. Any adjustments that I made to get deep bass seemed to make a huge spike in the 40-60 Hz range. I won't discount that this could have been partially the fault of my living room as well. Believe Crutchfield when they give the YST-SW150 a -6 dbl rating at 20Hz. I steer clear of "compact" subwoofers now. You simply cannot move the volume of air necessary to recreate low bass frequencies with small woofers. I shoved it in a corner for a while, which only made them boomier. Eventually, after about 2 years of use, the power supply died. I never could get the auto detect feature to work quite right, so I usually left them on most of the time. I imagine that's why the power supply failed. I wouldn't advise someone not to buy them, they are a good value for the price, but know what you are getting into. If possible, save up for a 10-12" downfiring subwooofer. The YST-SW150 is versatile; you can hook up satellite speakers to make a decent 3-piece system. Even after all my whining, I will probably get the power supply fixed and use it in a bedroom or other listening area. After all, it has been around the world and back with me!

Tight bass, quick response, great for music, nice features and controls, sleek design, plays very low

sleek yet too big for my room, terrible for HT, 150W RMS never heard or even felt for that matter, very hard to place and tweek

I really thought I was getting a good deal for the price and the power which was stated on the box. I placed it in many different positions in my room, and tried different volumes, setups, and crossovers. No matter what level input it was placed with it never sounded better. I have a Pioneer VSX-D509S receiver which I turned on: LOUDNESS,
SW +10 (subwoofer vol.) , and on Theater 2. A lil' louder , but not movie loud. I returned it and bought the SAW-M20 by Sony. The Sony kills the Yamaha, and is quite easy to place and setup. I plan on holding onto the sony until I can get the SAW-M40.

I purchased this product for a ridiculously low price (less than 250$ US), and wouldn't have minded paying more. Living in a small apartment with a low-to-mid quality theatre/ music setup, it fit the bill perfectly.
Mostly listening to music, I find it most pleasing on jazz/ fusion (e.g., Chick Corea, Hancock, Miles), Enya-type material, or any other accuracy-specific music (accuracy being a relative term - remember the "low-to-mid quality" setup). However, listening to older Slayer and Overkill records also brought the transparency of this sub.
I set it in a corner, crossover @ full CCW (40 hZ). Fills the room with ease. A recommendation for apartment owners or others in this price range who desire medium volume quality rather than sheetrock-cracking power. Only gets 4 stars because there is no such thing as a perfect transducer!

I wished I would got the Paradigm PDR-10 instead for about $10 less! This sub sounds good since it has 2 8" woofers in it. The quality is fine too. The only and pretty majoy problem I have is: when auto on/off is active, you have to turn your music volume all the way up in order to turn the sucker on. And when listening music at lower volume, the sub would turn itself off!
Don't get me wrong, it is a fine subwoofer, and the only problem I have with it is the auto on/off feature. If you don't live in an apartment, it'll be a good sub since you can always turn music loud, other wise, don't get it.

Last spring i bought this "subwoofer". it was BIG mistake. Luckyly, i don't have this crap any more. Bass was like there would be pot inside the cabinet. This "subwoofer" ruined totally sound of my hifi. No dynamic bass, no pressure, no nothing.. Don't buy this.

I bought this sub to go with my home theater I have Acoustic Research L.R. and center channels the two ar's have 2 8" woofers in them I set the sub in the corner of my apartmemt. With my Yamaha reciever I set it for having small left and right channels and the bass to sub only. The begining scene in 007 tommorrow never dies is simply incredible. It shakes my apartment and the one below me(their pictures fall off the walls!!) Needless to say I am buying a house and will definetly bump up the volume on that sub. Overall I am very happy with it. I had taken a look at models from Jbl, Cerwin Vega among others they all sounded terrible expecially when the volume was turned up. The cabinet they had even shook. I have never seen or heard this with mine and am very satisfied.

I bought my SW150 for $799 (AUS) for my average Yamaha surround system. Placing the subwoofer was very difficult in the lounge despite the phase setting. My lounge room isn't closed off it's open air so the bass doesn't rebound off any walls.
The problem i had with it was that the SW150 doesn't have a over-load protection circuit, so you can blow the drivers without even knowing it...and it doesn't handle bass that well at high volume levels. But keeping the music soft and turning the sub to max, the quality is quite good...
Also that 2 x 8" woofers doesn't move enough air for you to really feel the bass in movies, it's rather on the boomy side. Since the woofers are small, i blew my first SW150 without me knowing it...

But the SW150 will perform well in enclosed areas, you just have to be careful how hard you drive the woofers since there's no over-load protection and that ground-shaking bass can't be felt with 8 inch drivers...

I bought this sub to augment the low bass in my Sony mini-system. I have to say I was disappointed in this subwoofer. For its large size and servo feedback system, I was expecting a lot of smooth low bass. The output was rather dissapointing and at moderate to high levels it produced a lot of distortion. I have since heard bigger, better bass in a smaller subwoofer for lesser money. I had to take it apart to see the quality of the drivers, dont, you will also be dissapointed. My reccomendation, build your own home subwoofer.
