'[EE] (UK) Sources for smallish high-impedance spea'

Hi guys,
  Does anyone happen to know of a supplier (ideally UK-based) of small
(3-inch), round, high-impedance (25 ohms) loudspeakers?

  The speaker in my Eton E5 shortwave receiver has blown (proven by
careful application of an oscilloscope to the speaker leads) and
naturally nobody seems to stock a suitable replacement...

  For reference, I need:
    - Round profile, no mounting lugs, 77mm / 3-inch diameter
    - Ideally 25 ohms, or as close to that as possible. I'm not above
airwiring resistors over (or in line with) speakers! :)
    - 1W or so power handling capacity
    - About an inch deep

The existing speaker is a paper-coned cheapie thing, 77mm diameter,
round profile, 1W, 25-ohm impedance. The important thing (to me) is that
it has similar electrical specs to the original, and that it fits the
casing. Admittedly the latter is more important to me -- I don't want to
have to hack up the rather nice looking E5 casing to make a different
speaker fit.

Thanks,
--
Phil.

The nearest I can think of is a 100 ohm speaker used in model railways locos
for sound.

See http://www.esu.eu/en/products/accessories/loudspeaker/ for
possibilities.

The (official) UK distributor is Southwest Digital
http://www.southwestdigital.co.uk/ and they should be able to get you any of
these.

Would this be suitable? 16 ohm rather than 25, but about the right
diameter and has mounting holes built in.

Apparently my E5 (the radio I'm repairing) is based on an earlier design
(the Degen DE1103) which used a 16-ohm speaker and the same output
circuitry, so a 16R would probably be a good replacement.

It's just that the existing speaker was round, and those triangular
mounting ears are going to mean I have to either get the Dremel out, or
butcher the case.

Ideally I want something the same size and shape as the existing speaker...

I've found an 8-ohm 3-inch round paper-cone speaker at a surplus
supplier (Bowood Electronics) that has a larger magnet but is still
about the same depth and I'm thinking about buying a couple to play
with... not least of all because they're selling a few other neat things
I want :)

Just I'd rather have the exact replacement.. I'm probably not going to
find one, though.

Cheers,
