Product Research



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.


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.


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.

I`m sorry but Crutchfield should help. I bought two separate sub`s & had bad luck with both. I think trouble is in my Yamaha amp, how ever Crutchfield was very helpful in both case`s, sorry Bill. [ WILLIAM C  Jan 25, 2018 ]
I can't imagine this wouldn't work, but can't say for sure. You still have level control on the sub. I love mine. Sounds great. [ George  Jan 25, 2018 ]
Yes. Our on off configuration controls both the main projection and sub woofer [ HERBERT  Aug 18, 2017 ]
Call Crutchfield, they'll know. [ David  Aug 15, 2017 ]
The on/off works just fine foe my unit. Means 1 less remote to have next to me. [ Henry  Aug 15, 2017 ]
I do not believe so as it does not work with my Sony receiver. I usually leave them on as it does t bother anything. They do sound good to. [ FRED  Aug 14, 2017 ]
It should. I have an older Yamaha receiver and it works for mine. [ Julius  Aug 14, 2017 ]
The Yamaha YST-FSW150 can connect to the NAD D 3020 via the subwoofer output on the NAD. The Yamaha would complement the NAD D 3020 nicely in a desktop stereo system. I hope that helps! My Bio: [ Larry  Aug 22, 2016 ]  Staff
The Yamaha YST-FSW150 has a rear mounted mono-RCA Line Level input for use with any receiver, amplifier or powered soundbar system featuring a subwoofer pre-out jack. It also features a 3.5mm minijack port for connecting the supplied system control cable between the YST-FSW150 and your Yamaha receiver (equipped with a system connector jack). This makes it so the power of the subwoofer can be controlled by the power button of your connected Yamaha receiver. So it can be paired with any other receiver or speaker system, but only offers system control compatibility with select Yamaha components. My Bio: [ Larry  Feb 04, 2016 ]  Staff
It should work because the "system control port" send power to trigger the subwoofer and the Yamaha RX-A750 has a 12V trigger output. [ Paul  Nov 30, 2015 ]  Staff
I've been a Crutchfield customer for nearly 30 years and keep coming back for the great products and outstanding customer support. Ask a tech at Crutchfield for compatibility with any specific system. They are great. As for the Yamaha YST-FSW150 compact subwoofer I purchased, I connected it to a vintage Yamaha Natural Sound CD Receiver CRX TS10. . .with spectacular results. Good luck in your search. [ Raymond  Jan 06, 2015 ]
Matthew, You will have no problem with compatibility using a mono RCA cable. I have a Yamaha subwoofer connected to my Visio soundbar through a RCA cable in our living room, and the sound is excellent. You will have to balance the amount of bass required from your subwoofer with your soundbar to get the optimum overall sound. Regards, Tobias [ Mr.  Jan 02, 2015 ]
yes it will work and should be a nice addition to your system [ DAVID  Dec 08, 2014 ]
I have two of these speakers there great it should work with any receiver. [ EDWARD P  Dec 08, 2014 ]
I had Onkyo and used HSU sub but I now have a yamaha amp and use this because the HSU was too big for my space. I can't see why this wouldn't work very well with the Onkyo. [ ARTHUR  Dec 08, 2014 ]
I have one on it's side yes you can [ EDWARD P  Dec 08, 2014 ]
I would assume you could place the unit on its side. I believe the bass is enhanced by the downfire into the shelf it rests on. It would definitely look better in its designed orientation, but if that isn't an issue for you I would think you will be ok. Perhaps placing it on its side with the feet as close to a side wall as possible would be an option. The reason I purchased this particular unit was because of my entertainment center design. I would have preferred a more typical upright subwoofer as I believe the design allows for better bass response. [ Edward  Dec 01, 2014 ]
Absolutely, it can be oriented vertically with no issues. I actually have mine in that exact setup, as I wanted to hide it behind my one couch, and it works awesome, great sound from such a compact unit! Also, the round (silver) feet you see in the picture are also easily removable! (one simple wood screw in each). I absolutely love this sub, it's perfect for where I have mine (main family room) where I want to hear it but not see it! [ MICHAEL  Dec 01, 2014 ]
