New speakers for Mk1 - advice please!!!

All,
My Alpine speakers in the rear shelf of my MK1 have finally died - not bad for 15 years of use!

So in the market for new pair! Don't want to spend more than ?60-?70, and want to just replace - so looking for 17cm/6.5inch jobs. The old ones were 3-way, but only ones I can see in that range are Pioneer. Does anyone have any other recommendations?

They were mounted on a sound board - not in original speaker holes.

Cheers
Dave

Have a search of the site using speaker as key word . Remember seeing a few posts about them with links .
