I bought these a few years ago along with some spare drivers. T27’s and Coles super-tweeters weren’t going. But it was more than a speaker swap - the crossovers were shot. After a long delay both for delivery and installation the new Falcon crossovers are in and going well. I have one Coles open-circuit to fix or source a spare for, but in listening I can hardly tell the difference. A bit of false start with lack of left-right balance, but it turned out to be a source component.

Wonderful synergy with the A&R Cambridge A60 amp and the Arcam Alpha Plus CD player (TDA-1541a - and very well implemented) - so much power. The Technics SL-1100 is running an Audio-Technica AT30E MC cart (MC installed in A60). The Apple Airport Express is fed to the Parasound D/AC-1100 with its PCM63 chips - so reasonably contemporary. Next project is to assemble a Raspberry Pi Roon endpoint that will feed 24bit to the Pararsound (which has 24bit chips installed).

There’s a heap of non-connected stuff there as well in that pile, but essentially stuff with a “light on” is connected.

I do enjoy the transmission lines. Room is a bit small for them but the way I would say it is, “normal speakers push sound at you, and it can get tiring - with transmission lines the whole range of the sound is just “in the room” - you get good bass that flows in a fully integrated way with the full sound spectrum - its just sound in the room with you”

Anyway, a long delayed project now up and running, and again, the synergy between the R50’s the A60 and and the Arcam Alpha Plus CD player is just superb - enjoying CD’s again.

I recall the A60 and Alpha player making some very nice music back in the day. But not seen or heard those speakers.

V cool bit of cabinet & grille design, those R50s.

There's a set at my niece's house - you can see one in th background in pics in this thread:

Ha - you said you knew of one other pair in Auckland - they look mint. She has very good taste. Mine from 1974 - with the later plastic grills, and rated 50w rather than the original 25w. You asked me back in 2017 how the refurb was going ...... answer ..... 4 years! I bought these to replace B&W DM2a transmission lines, the only speakers I ever regret having sold. But now these are running properly, my transmission line "fix" is happily resolved.

Are those DM5s or DM4s sitting on top?

DM4's - excellent speakers - got them with the 5000x - go well together.

Finished this restoration today, partly in homage to Owen who was very helpful back as far as 2017 when I started the project (I think one of his extended family has a pair). Today I installed the final part - a replacement for one of the Coles 4001G super tweeters. When the crossovers were installed it was found that one of the Coles was open circuit. Last week I was donated an old pair of B&W DM4's - one speaker was intact - the other was without mid or woofer or crossover - but did have a working Coles. So today that Coles went into the Cambridge R50. I do love these speakers - even better than the DM4's. I opened up the dead Coles - for all the talk about having nice thick speaker cables the wire from the solder tabs on the back of the Coles into the body of the driver wasn't "wire" so much as a mere "whisker" - much thinner than an actual cat whisker or hair. The only wire I have seen that thin was inside a Dynavector cartridge. Anyway listening to Telemann: Recorder Sonatas and Fantasias with Pamela Thornby and appreciating the moment.
