B&W Speakers Series 80 Model 801

hello, i have a set of model 801 speakers and the woofer is blown on one of them. they are in great shape with covers and other extras intact. does anyone know if there are resources to find parts or have an opinion about whether or not they are worth getting repaired or trying to repair on my own? i'm handy but by no means an expert. they were passed down by a family friend along with a big yahama amp and pre-amp and have sentimental value, but they are starting to take up too much space. thanks for any input.
