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 5áby 37 reviewers.
Rated 5 out of 5áby 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 5áby Perfect replacement Bought this as a replacement for my old Pioneer sub (part of the ú99 5.1 system on here) after it stopped working. Only about ú20 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 5áby 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
Rated 5 out of 5áby Great product, great size Fantastic service most of all by Simon, store Manager at Kingston Branch, bought a set of KEF 180 for ceiling in loft, but sounded a little "tinny" so Simon helped to sort out. Flexible, great attitude, and allowed me to change products until got the correct one that worked well. Yamaha sounded great, solidly built, but had to change because even this too big to fit in my niche space, so upgraded to CA Minx - Simon was great at facilitating exchange. highly recommend service! They will get it right for you. 21 June 2015
Rated 5 out of 5áby Does what a Subwoofer should! Combined this with a pair of Cambridge Audio Minx MIN 11's for a bedroom system. They seem to go together perfectly - the sub is small enough to tuck away unobtrusively, and reinforces the sound without being overpowering - very "musical", but still plenty of oomph when playing Call Of Duty in bed (sorry Wifey!). Thanks to Kieran at Reading for sending it over so quickly - excellent service! 22 May 2015
Rated 5 out of 5áby Brought my old Yamaha M330 to life What a massive improvement this subwoofer made to my old but effective Yamaha M330 which I needed to work in a larger room but did not want to spend vast sums on a new larger system when all I needed was DAB and iPod. Coupled with Cambridge Audio 500 cable, the setup could not be easier. 22 May 2015
Rated 5 out of 5áby Yamaha subwoofer This sub has made a massive difference to my viewing experience, it's running alongside my jbl soundbar, music and films sound so much better with a rich deep sound of bass which this sub delivers, I'd recommend this sub to anyone who wants to better there sound quality and get that cinema feeling. 10 May 2015
Rated 5 out of 5áby Great value Easy to set up only had to Google the site of control lead to Yamaha amp. Great sound. Good value. 09 May 2015
