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!

Low profile cabinet

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.

Linear Port
Using a down-firing woofer and Yamaha's award-winning YST active technology, the flat Yamaha subwoofer delivers surprisingly powerful bass. 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 4.8 out of 5 by 61 reviewers.
Rated 5 out of 5 brilliant product for the money A good add on to my 6.1 system. Just what I needed for good cinema at home experience. 24 January 2016
Rated 5 out of 5 by compact box that packs a nice punch Been after one of these for a while ever since I bought the YAS101 soundbar, and now the price drop thought an absolute bargain, and was not disappointed for such a neat little unit fits perfect behind the tv and sends out a glorious deep sound to enhance every bang, thunder clap and roar of an engine, not sure neighbours agree but hey ho. And connects to soundbar so no scrabbling around back of tv for on switch. 11 January 2016
Rated 4 out of 5 by Yamaha subwoofer This is a very good addition to my Canton sound base. 10 January 2016

Rated 5 out of 5 by Surprised I brought this to replace my aging eltax atomic A8, all I can say is wow!!. Fills my room with thumping base. Great for the price. Simple to set up. 07 January 2016
Rated 5 out of 5 Very pleased with this product Found the people that work in Richer Sounds very helpful and passionate about the products they sell. 05 January 2016
Rated 4 out of 5 by Amazing value subwoofer I replaced a JBL passive subwoofer which had failed. I read some reviews and went to the shop to have listen Compared sound with a different unit costing more than double, and decided this was good enough to complement my current 5.1 system (Bose & .JBL}. When I plugged it in on the floor behind the TV, I was staggered how good it was. I changed the crossover frequency to 110 Hz on my AV amp, and my sound system is just brilliant. Films now sound so much more exciting and the floor shakes, and much to my surprise I sense the air flow from the sub even though I sit 10 ft from it. I consider this an excellent buy. 27 December 2015
Rated 5 out of 5 by Excellent Excellent product, works perfectly, really good deep bass sound, linked to a Yamaha AV Receiver., 26 December 2015
