Telefunken RB46's, anyone familiar with?

[TJet54]

In excellent (cosmetic, so far) condition, I just acquired these mid-century modern Telefunken RB 46 speakers.
I believe these speakers were paired with Telefunken's Opus 5550 MC and Opus Studio 5650 MX radios, possibly more.
Does anyone know the impedance and power rating for these beauties? Thank you, Steve

So far I can't find any specs on those. Even Radiomusuem doesn't have anything useful.

If I can find anything I'll post here.

Cheers,

You can determine the impedance very easily - just put a meter across the terminals and measure the resistance, than add about 30% to get a nominal impedance figure.

As for power, does it really matter? As long as you don't crank them up to daft SPLs they'll probably cope just fine.

One clue is that the RB40, 41, 65 66 and RB70 are all 4 ohm. I can at least find a bit of data on them, all '60s production. Most German speakers are 4 ohm.

Those are all 2-way, 2 driver speakers. The RB40, 41 and 65 are rated at 15w, the RB66 and 70 @ 25w.
