(Does this mean I suffer a lot less from 'bias effect'....??? :-)

Hi Keith, I don't think it does, I think you are nearly (only nearly :-)) as
biased as the best of them, however, whenever we prefer one thing over
another I think we are demonstrating a bias toward what we prefer in many
instances. Our bias may be because of many reasons that are at variance with
the reasoning of others. So What! We all have biases in some area or
another.

I picked up a set of old home made speakers today without knowing what was
in them, but I could see through the cloth that they were fitted with a 12"
driver. The boxes are three feet wide and three feet high. When I got them
home and pulled them apart I find a Wharfedale Super 12/FS/AL 15 ohm driver
in each box. They were mated to an Atomix HTM-2 Japanese made tweeter (fair
bit of corrosion in the chrome finish). My eyes lit up a little until I
realised the drivers are not a perfectly matched pair. The cones, while they
appear original, differ in the number of concentric ridges in each cone.
Also, the foam surround on one is not in good condition at all. I would say
that one of the drivers is a later model then the other. Both cones have the
white writing (fairly faint) on the outer back edge that was evidently
placed there in the factory by QC.

I thought of you as one of the perfect people to build something to put them
into, however, they are unuseable as they are because of foam rot.

I have already put the tweeters on eBay here in Aussie (listed world wide so
you will find them in the UK). I haven't been able to find any info on the
tweeters on the net other then a few pictures on a japanese forum. It was an
interesting aquisition but one I really don't have any use for. I would have
much prefered the drivers to be from the later series AR3a's.
