Great product 5 stars 5 out of 5

Bought this woofer to replace one in a Whafedale 2.1 system subwoofer. Looks so much more substantial.
Needed to make an adaptor as the mounting holes where closer than the original for the same size cone - the discription doesn't show the hole centrers for the fixings

Delivery took longer than stated in the order confirmation
