how to replace woofers on a Linn akurate 242

I have a linn 242 front speakers and the bass drivers seem to be blow.
I have an old 225 that I could use to get the 2 woofers. I cannot figure out how to get to the woofers and have combed the internet to no avail .
I live hundreds of miles from a dealer any help would be much appreciated.
Thank you,
