Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Features

Advanced YST Technology II: The Advanced Yamaha Active Servo Technology is a unique system in which the speaker and amplifier work together to cancel out impedance so the speaker unit has a perfectly linear motion. By doing this, the YST-FSW150 ensures the highest levels of sound pressure and overall performance.

High Efficiency Amplifier: The 130 watt dynamic power amplifier used in the YST-FSW150 is capable of delivering large amounts of reserve power for accurate reproduction of high energy peaks needed for those extreme action movie moments that require a heavy dose of bass. This technology also emphasizes the dynamic qualities and provides a sharper sound image for music listening.

Driver: The YST-FSW150 uses a down-firing 6.3125" multi-range woofer to create tight and accurate bass. The 6.3125" woofer is also video shielded so you can place the unit close to your TV without harming the Television.

Linear Port Design: The YST-FSW150's bass reflex enclosure uses a front-firing linear port to minimize extraneous noise which helps offer distortion free bass notes.

Mounting: The Yamaha YST-FSW150 powered subwoofer's enclosure design is engineered to be mounted horizontally or vertically. The powered subwoofer features four attached feet which allows you to mount the unit horizontally for a low-profile installation. The YST-FSW150 also comes with a vertical stand and four self-adhesive non-skid pads that allow you to mount the unit vertically if preferred. The unit's subwoofer will be side-firing if mounted vertically.

Controls

Power: This control button powers on and off the YST-FSW150.

Volume Control: You can adjust the volume level (0-10) of the subwoofer to match the level of sound from the other speakers in your application.

Connections

Line Input: The subwoofer has a rear mounted mono-RCA Line Level input. This input is for use with receiver or amplifiers featuring a filtered subwoofer pre-out jack. You may need a "Y adapter" to connect the left and right outputs of your receiver or amplifier to the YST-FSW150 if your receiver or amplifier features a stereo subwoofer output..

System Connector: The YST-FSW150 features a 3.5mm minijack port for connecting the supplied system control cable. By connecting this cable between the YST-FSW150 and your Yamaha receiver (equipped with a system connector jack) the power of the YST-FSW150 can be controlled by the power button of your connected Yamaha receiver.

Gives new depth to bookshelf speakers

Written By Bill, Florida on Tuesday, March 25, 2014

Crutchfield Customer Review (What's this?)

This sub gives depth to our Polk Tsi 200 speakers. At first we were reluctant to try a sub because we didn't want the "boom, boom, boom" sound and vibrations. We just wanted to make our existing speakers sound even better. And that's what this Yamaha sub does. It fits on out bookshelves too. We did have some trouble setting the receiver to work with the sub, but the Crutchfield tech support helped us set thing up right as always.

Pros: well integrated bass, sub fits on a bookshelf,

Sub(s)

Written By SDC, Grafton, MA on Friday, January 17, 2014

Crutchfield Customer Review (What's this?)

I purchased a 150 a few years ago and found the base to be a little shallow until I set it on it's side with the speaker against the wall, which helped. My wife decided (for me) that in our new house the sub needs to be placed within our equipment credenza so that is where the sub went and so with it went the base depth. I purchased a second sub and placed it on the shelf right above. The look great and sound great also. The base is not as deep at my old velodyne UDL 12 but with no foot print and great looks, two 150s was a great choice.

Pros: Fits in equipment cabinet on a shelf, has great looks

Cons: Shallow base, I needed two to fill the room

Great product, as long as you aren't looking for huge bass

Written By Drew, Austin, TX on Thursday, August 08, 2013

Crutchfield Customer Review (What's this?)

The form factor is great for me and fits perfectly in the cabinets in my family room. Setup is ridiculously simple, just plug in power and the subwoofer cable and you are on your way. As you would expect with a small subwoofer, the bass is not overpowering. A nice addition if you are looking for subtle bass, but probably not if you are looking to crank up the latest hip hop album. It would be great to have remote control capability, it's a hassle to manually turn it on and off every time.

Pros: Unique form factor is great for adding to your entertainment center, looks great, easy to set up

Cons: Bass is not as strong as larger subwoofers, might not give you the punch you are looking for (especially for music)

Ok for Small Speakers

Written By Djdj, Salt Lake City on Tuesday, August 06, 2013

Crutchfield Customer Review (What's this?)

Ok so my setup is denon avr 1613, pair of polk tsi 400. Mostly music listening with a few movies. I purchased the Yamaha subwoofer to compliment my speakers....well I returned the sub....Crutchfield support is awesome also thanks for the. Tsi 400s they sound great

Pros: Slim

Cons: Not much "punch"

Great for tight spaces

Written By TM, SFBay, CA on Thursday, May 16, 2013

Crutchfield Customer Review (What's this?)

Requires a pre with bass filter capabilities, but you should know that going in. Does a good job at rendering low level details without shaking the whole house, and I really like the ability to power on/off and adjust volume from the front panel.

Pros: Great for utilizing rack space instead of floor space; reasonable price.

Cons: Lack of low/high pass filter may be a deal breaker for some.

Decent

Written By RD, OH on Monday, August 27, 2012

Crutchfield Customer Review (What's this?)

Gave me what I needed without overkill. The typical theater sound setups tend to lack good bass response without a Sub, and this filled that sufficiently filled that gap.

Pros: Good price, and doesn't take much space. Appears to have solid bass response.

Cons: None so far.

Great Space Saving Subwoofer

Written By Paul, West Lafayette, IN on Thursday, December 01, 2011

Crutchfield Customer Review (What's this?)

I was interested in this sub because of it's unique size. My wife didn't want a large sub sitting on the floor of the living room and she liked that I was able to place this one on a shelf below my components. I was skeptical at first that it wouldn't sound very good but once I plugged it in and tested some movies and music, I was pretty impressed with the sound. If you need a small, space-saving sub, this is a great solution.

Pros: Great size. Sounded better than I expected.

Not for everyone

Written By Phil D, Easton MD on Sunday, November 27, 2011

Crutchfield Customer Review (What's this?)

The size/form factor of this product was perfect for my application. However, the lack of a crossover frequency control is a big disadvantage. The out of the box crossover frequency (~154Hz) is too high for me and I'll bet most applications unless you have really small main speakers.

If you don't care about the warranty, it only takes 3 resistor changes to drop the crossover frequency.

So, now that I have voided my warranty and dropped the crossover frequency, I am pleased with my purchase.

Pros: Size/Form factor

Cons: No crossover frequency adjustment.

Great Sub and Small Footprint

Written By Dave, Covington Va on Wednesday, April 06, 2011

Just bought this speaker, but have been using it for a week.
Boy is it great!! Tight Bass, no booming, have it on its side so it takes up
even less room. I tried another sub from Infinity, and although this is a
little more expensive it has better sound and is smaller and lighter

Made for each other

Written By howard, Bellflower,CA on Sunday, January 25, 2009

Crutchfield Customer Review (What's this?)

This small subwoofer is connected to my Yamaha YSP-1000 in my living room, a small 15'X15' space, and truly makes the movies come alive on my SonyXBR. I have not used my Yamaha Receiver with it's surround six speaker system since adding this YST-FSW150 to my old Yamaha YSP-1000 sound bar. Wow, suddenly I realize I don't need all the extra sound equipment on my Bell'O entertainment stand. See, less IS sometimes BEST!

Good sound in a small package.

Written By Benjamin, Hampden, ME on Thursday, August 28, 2008

Crutchfield Customer Review (What's this?)

I got this subwoofer to place under a custom make stereo shelf and it fits perfectly. It produces a decent amount of bass for its small size, but don't expect it to hit like a 10" or 12" woofer. If you tune it to match the volume of the other speakers, you can crank up the music and it doesn't distort or bottom out. And one of the nice things is when it's powered on or off it doesn't make a harsh snapping or popping sound like some other models do.
Something to keep in mind is that it lacks a cross over dial to limit the high end frequencies, so it does reproduce a little more then it needs (Ex: 100+ Hz range). But this is not an issue if you can limit it from your receiver.
Over all, a well designed, good sounding woofer for those looking to round out a small stereo setup or space conscious surround sound package.

Great Solution

Written By matt, Memphis, TN on Saturday, July 19, 2008

Crutchfield Customer Review (What's this?)

The sub sounds even better than I expected. It is small enough to fit under a shelf and projects extremely well. If you need a small sub, this is a great solution.
