Thanks Andrew
This actually I think completes the picture of the blown bass drivers of the IMF speakers.
The seller mention that when he plugged in an amp it went bang/pop etc.
The speakers came with some very dodgy cable which I threw out. Just retrieved them to take a pic and as can be seen the covering was brittle exposing the wires. Likely that when he plugged the amp in he disturbed the wire, creating a short, blowing the rh amp channel and then the bass drivers.
He had the speakers for 18 years and one lapsed moment destroyed his pride and joy.
Thanks for the tip on measuring a solid state amp output.
On RCA outputs, to test say unknown items, what would I be looking for?

that speaker cable is one hell of a lapse

I'm Alex.
I have original Dalines 3 unit version, KEF B110, KEF T15, Coles 4001G, and yes, even with the small B110 they go down really low, I would say lower than 30HZ. However, one can't have disco levels!
The two unit version was B110 and T27.

I was just thinking of how to check for correct operation and possibly have a source playing through it. So, for example, an old cassette player or CD player.
As mentioned earlier I normally use a sacrificial amp or speaker to test things but easier just to use a multimeter.

As there were questions about amplifier failure, I thought this might clear things up: https://www.analogbros.com/tech/articles/goodgobad.html
So after a bit of a lul I've managed to source some correct drivers for this project from the USA (thanks Grant) and today plugged them in. Mind you a bit of a faff bringing stuff in from abroad what with import duties and Parcelfarce seemingly having a monopoly on imports. But no damage thankfully.
Immediately obvious that these speakers are something special. Full coherent sound across the range with great definition and punch. Played my usual array of test tracks and the IMF comes up trumps. No wilting around the edges and running away.
As the speakers have the active lines to boost the bass I played tones through it. And yes they do go low. Good tight sound at 30hz and improves from there. Obviously not bass that rocks the walls (and anyway only two 6 inch drivers) but nice bass. On the other extreme I could get to circa 15khz but nothing beyond that. But I assume that is more a factor of my hearing and/or the aged caps.
So now will ponder if I do a recap and wood restore. I think a recap will enhance the definition and open the sound up in a worthwhile way.
Although the baffles have screws it looks like they are solidly glued down as well so may be an issue of getting to the crossovers easily. The crossovers can be seen from the bottom bass driver but can't be retrieved without removing the baffle.
