HD.

I found a 1970's Philips car extension speaker which, when connected to my own 9R59DS, performed as well as the speaker supplied by Trio.

However the external finish is poor including rusting of the mounting bracket. It would have been FOC, but I don't think your spending £2.90 on having it posted to you would have been good value for money. Sorry.

Unless you plan on spending a fortune I think you'd do best buying a driver unit as suggested in post #12 and making your own enclosure. I have to confess that the speaker used with my JRC NRD-525 is just a bare driver unit stuck to the side of a filing cabinet using its own magnet.

You could also try FreeCycle or even look for a scrap domestic radio from which you could use the speaker and cabinet.

Incidentally the mains hum from the speaker was at a very low level even though my own set still has its original smoothing capacitors and the mains transformer hasn't been repositioned.
