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 out of 5áby This product is good value for the money Have come across better Subwoofers but this is fine if you don't want to spend a fortune 16 September 2016
Rated 5 out of 5áby Wow - What a difference First I must say that I didn't listen to any Subs before I brought this one and so my review isn't based on this model in comparison with anything else, its just my ears hearing the difference between my existing setup (Yamah Amp, B&W fronts and Cambridge Audio centre) and the addition of he Yamaha YSTFSW050 (what a great name!) However, Im a musician, a caring amateur sound engineer and a lover of films with exploding helicopters so I have a sense of what things could and shoud sound like. The size of the Yamaha rebasser (much better name I think) means it fits under our coffee table/tv stand and is the same size as my av amp. My amp has that great setup mic so all I had to do was plug it in, turn it half the way up and run the mac/audio setup. The sub fits perfectly in my setup. Both physically and audio-ly It has presence but doesn't dominate. The sound space is much larger but unless you turn it up to 11 it sits under everything else like a comfy sofa. 12 September 2016
Rated 5 out of 5áby Hear what you've been missing all these years I use studio monitor speakers for general listening. They're specified down to 35Hz but, of course, are designed to be used close to your ears and were never intended to deliver room-filling sound, especially at lower frequencies. As I tend to listen to pipe organ music, a good room-filling bass is really needed when the reeds on the pedal board are opened up. So I added one of these Yamaha subwoofers. I must admit being a bit sceptical because they also are specified down to 35Hz, the same as my main speakers, so wasn't sure if I'd get much advantage. Imagine my surprise! Quite honestly I'm hearing an extra octave, or more, at lower frequencies; and those notes from the organ reeds are growling their way into the entire room. I'm really hearing things I've not heard before from my CD collection. The floor of my living room is concrete but I can still feel it vibrate! I really couldn't be more pleased with the way this remarkably cheap unit has transformed my listening. 13 August 2016
Rated 5 out of 5áby Excellent low frequency response. Works well with my Yamaha amp I have had my living room wired for this sub woofer for some time and at last have got round to using it. Excellent results with a thumping bass which matches well with my surround sound set up. Perfect for cinema quality sound when watching films such as The Matrix. Easy to set up. Excellent value and service again from Richer Sounds. 12 August 2016

Rated 4 out of 5áby Great value for decent base I brought this unit as it was one of the cheaper units and compact. It has plenty of power and the base is really good, for films and music. It will take up half a shelve space on most TV cabinets. Would recommend it. 07 June 2016
