This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:

Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.

Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.

Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).

45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.

If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*

* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty.

The Yamaha YSTF-SW050 is not like other subwoofers.

With its specially designed, low profile, cabinet, the YSTFSW050 has been designed to fit where other subs won't go. Mount it on a rack, alongside a mini system or under furniture, the YST-FSW050 will slide in with ease.

Using a down-firing woofer and Yamaha's award-winning YST active technology, the flat Yamaha subwoofer delivers a surprisingly powerful bass response. With its front-mounted Linear Port, the YST-FSW050 produces its bass smoothly and progressively, thus minimising distortion.

Perfect for use with a Soundbar, mini hi-fi system, or anywhere else where space is at a premium, the Yamaha YST-FSW050 is that very rare thing; a discreet subwoofer!

Rated 4.7 out of 5†by 42 reviewers.
Rated 5 out of 5†by Amazing sub Brought this to add a bit of depth to a set of ceiling speakers in my kitchen. Looks great and sits very nicely onto of the units very impressed with the sound. All in all over the moon with my purchase 30 September 2015
Rated 5 out of 5†by perfect marriage Bought this subwoofer to match my Yamaha YS101 Sound bar after 10 mins of reading sound bar manual it was up and balanced and working perfect bringing out sounds from films I didn't know were there When set on full it can be felt all around the room 16 September 2015
Rated 5 out of 5†by Perfect pairing to my Rx-v677 Purchased this after discovering my old passive sub was not compatible with my new AV receiver (the Yamaha Rxv677). I know....should've checked/realised this at the time of purchase. Anyway, ordered this online and it was delivered very quickly. Easy to plug in and set up. Also as I was pairing with a Yamaha Receiver I was able to use the trigger supply to operate the power on the sub automatically so no need to turn on/off separately. Bass is good considering the size of this unit and certainly picks up a lot more of the low tones than my previous Denon set up. Overall I'm very happy with how this sub performs. At this price point don't think I could've got more for my money....specially as I was pairing to a Yamaha receiver. 09 September 2015
Rated 5 out of 5†by Budget sub woofer that will fit in low places This is the only sub I could find that would fit in the space I have. Very basic but does the job well and looks pretty slick too. I would recommend this if you want a small cheap sub. It sounds better than the old one I had too. 08 September 2015
Rated 4 out of 5†by Yamaha SubWoofer Excellent value and nicely sized and powered for those not wanting dance floor booming bass. Works well with my Harman Kardon. 05 September 2015
Rated 5 out of 5†by Excellent looks and sound. It's a great looking SW that blends in nicely with my home cinema system. A perfect match for my Yamaha RX-V577 receiver and Yamaha CD-S300 CD player. 24 August 2015
Rated 5 out of 5†by Perfect replacement Bought this as a replacement for my old Pioneer sub (part of the £99 5.1 system on here) after it stopped working. Only about £20 more than getting the old one sent away for repair and a much lower profile made this an easy choice for me to make. Well worth the money if you're looking to upgrade your system. Also included is a cable that connects to your TV if it supports that function. I'm looking to upgrade my amp to a 4K 7.2 system so I'll get a relation (builds led's) to give the old sub the once over to see if it's just a case of a fuse / relay that needing replacing. Hopefully, this will saver the need to buy another sub when I get round to buying the new amp. 16 August 2015
Rated 5 out of 5†by Easy to use and don't take up lots of room The Yamaha subwoofer works great with my Denon CD receiver (which was another great purchase for Richer Sounds) it brings the sound to life with a lovely bass and brill when watching films on my Sony smart TV 04 July 2015
