The Engineer in me led to plots and graphs, but no pics of the speakers!!!

The bass driver is a classic Richard Allan unit, you can tell them a mile away by the red (sometimes blue and black) felt:

The midrange has a fair bit of the B110 about it's looks, though it is smaller and behaves quite differently. This thing is very much a product of it's era (1970's):

The surround on the midrange is stated as PVC in some literature I found. I kind of believe this, though it has been coated with something sticky. It is not sticky on the back.

The cabinets were in moderately good condition. There were some coffee stains on the top of one, and water stains on the side of the other. In the end I sanded and revarnished them.

The timber is a rich dark (mahogony or some similar) veneer. I think it came up pretty well.

I kept the cloth on the grilles - there is some room for cleaning here, but I kind of want to avoid completely stripping these down and redoing them.

All in all, these came up really quite well, and sound surprisingly good for their vintage.

Now I need to work out what to do with them, and I am floating in speakers!!!!!

    The tweeter is not a Celestion HF 2000, but ye olde Philips AD 160T8 or T4. Most certainly a replacement and not necessarily an improvement.
