Subwoofer for Keyboard instruments
Enrich bass to your keyboard's speaker
KS-SW100 is compatible with Yamaha keyboard instrument shown below.

New Twisted Flare Port Produces Clear and Tight Bass
The all-new Twisted Flare Port takes advantage of extensive subwoofer development experience. The flared, gently twisting shape diffuses the vortex of air generated around the edge of the port, creating a smooth flow of air. This reduces extraneous noise not present in the original input signal and provides clear, accurate low frequency reproduction. From special effect sounds in movies to the atmosphere of a live venue, you hear bass that is clear, tight and realistic.
Advanced YST II for Awesome Deep Bass
Developed by Yamaha, the Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant-current principles to drive the speaker cone with even tighter control than the previous version. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound quality.
Stylish Addition to Any Room
The gently rounded form with a slanted front surface presents a stylishly elegant appearance. Designed to be unobtrusive, It’s sure to look beautiful in a living room or home theatre room. Offered in black, walnut and white, so you can choose the model that best matches your other speakers.

Keysound reviews
Yamaha P145 Piano
Fantastic, help and advise from the staff and Steve, they went the extra mile.
Yamaha Genos 2XXL Keyboard
Excellent....above and beyond.
Yamaha Genos 2 Keyboard
From start to finish, my experience with Keysound was nothing short of exceptional. Delivery was easy, with my keyboard arriving as promised on time and in perfect condition. A good explanation of the Genos 2 was given to me on delivery and everything was setup ready to go. The USB they provided was helpful in exploring the capabilities of my new keyboard.
Any enquiries I had were met with prompt and friendly responses, and they went above and beyond to ensure that I had all the information I needed.
Overall, based on my experience, I would recommend Keysound for their combination of knowledge, reliability, and excellent customer service.
Korg EK50L Keyboard
Cannot find fault on service and prices. Will never use any other dealer.
Yamaha CSP295-PE Piano
Keysound are the most knowledgeable And helpful people ever I cannot rate them high enough. Our Piano was delivered on time and the guys told me at the time that the packaging was damaged when they unpacked the piano they found it to be damaged and told me before I even seen it. I had the choice to send it back then or keep it until the replacement was found. I kept it within two weeks. I’ve got a Piano. First rate service all around. I would highly recommend them

Roland Fantom 06 Keyboard
I have purchased several keyboards from Keysound , and you always get a good service. You get a more personal experience, and they are always willing to take time to find you the best keyboard which suits your needs. After sales is also good, as they will help you with your new keyboard should you get stuck on anything.
Yamaha Pre-Owned Genos XL Keyboard
Nothing too much trouble and great after sales support and assistance.
Korg PA5X61 Keyboard
Great personalised friendly service, extremely knowledgeable of the products. I would recommend Keysound, especially to those who require additional support or aftercare with the products they purchase.
Casio CTX5000 Keyboard
Keysound were excellent. Other music shops take a generic approach about what people want and they have limited experience across multiple types of instruments. Keysound were interested in me and exacty what I wanted. They interpreted that and gave me invaluable advice. It was friendly, focused and specific. I would definitely recommend them and buy from then again. I also really like their view that buying a keyboard from them is just the start of the journey. They are there for in-person and online/on phone advice and help. I am extremely pleased with my purchase - which is not what I thought I'd be buying when I entered their shop.
Kawai CN301-B Piano
Very knowledgeable and helpful to make sure we got the correct piano for us
Yamaha Genos 2XL Keyboard
Steve and his staff were excellent. They spent a lot of time explaining and demonstrating various digital pianos and keyboards. After a few days deliberating I chose a different option to what I had set out to buy. The knowledge and service was second to none and inspired me to become a better player. I am very pleased with my purchase and looking forward to many hours of keyboard playing. Thank you
Roland HP702-CH Piano
I am so pleased I chose to visit Keysound Hinckley and purchase my new piano from them!!
I went in store to browse as I haven't bought a new piano in about 15 years, and the person who helped me (Sorry, I didn't get his name!) was so so helpful and knowledgable. I purchased my piano and within a week got the call to arrange delivery the following weekend!
The piano is amazing, but unfortunately has an issue with one of the keys. And rather than sending someone over to fix it, the manager called me yesterday to say they'll arrange for the piano to be replaced with a new one!! He said he would be happy if a brand new piano already had an issue, so he'd rather I have a brand new one. Honestly, couldn't ask for better service and nicer people :) Thank you so so much.
Roland HP704-DR Piano
Good customer service from staff who knew their product. Plenty of time given for testing each instrument and making up mind.
Yamaha Pre-Owned P515-B Piano
Keysounds service was absolutely Fantastic, I can not rate them highly enough. The Piano I really wanted was unfortunately discontinued, they called me to explain in person and then managed not only find a preowned one that was in brand new condition but they found all the correct packaging so when I received it I thought it was actually brand new! That showed a level of care and customer service I haven’t seen for years! They also immediately refunded a portion of the cost which was a bonus as I could then buy the stool l wanted ( not from Keysounds )
If all companies delivered care & Service like Keysounds it would be a far better Country for everyone! Well done
Yamaha Genos2 Keyboard
