It took me about an hour to rebuild both speakers in my 30 year old Yamaha sub. The directions were easy to follow and the results sounded quite good. I should be good for another 30 years.
Great product. Easier to install than I was expecting thanks to the printed guide and youtube tutorial video.
Also, having the product description include the Yahama speaker model number helped me find this product and know it would be suitable.
Had my Yamaha Subwoofer for almost 20 years and this $40 repair kit was so simple to install. Ordered from the USA and delivered to Australia and got here a week earlier than anticipated.
This has made them sound amazing again.
