Tailgate speakers ?

Morning all, I'm after a set of new tailgate speakers for my 98 Disco TDI. The ones I have are frayed at the edges and are basically knackered, what I'm after is replacing the actual cones for new ones. I've looked on CPC and there are an array of speakers to choose from, and I can't find any markings or details on the ones I have in my Disco. I believe they are woofers and are about six inches can anyone shed any light on this if any experiance replacing them or maybe a link to some new woofers ?

Cheers

They are just standard car loudspeakers that receive a bass frequency nothing special other than the magnet has a threaded hole for fixing so take one out and go and match it up at Halfords or an ICE shop.
The subject has been posted before a few times so do a search,

i bought a pair of speakers for the the rear door and they even had the threaded hold in the center that was exactly the same as the land rover ones, they even fitted exactly the same anorl ! i was dead chuffed cos they wanst expensive,

Great !! where did you get them from?
