What do you think about these old Loewe-Opta alnico Fullrange?

[Peters8]

Hi my friends!
Please could you give me your opinion about these two alnico fullrange Loewe-Opta from the '50 ?
I 'm searching for high efficiency and good sound full-range speakers with a decent bass response (at least 80 hZ)...the high frequency is not a problem 'cause I can add a pair small tweeters.
In your opinion does the sound quality of these Loewe Opta speakers could be similar to the famous Saba Green cones?
Thank you so much in advance for your precious help and for your kindness.
Best regards from Italy!

They certainly look interesting. In terms of sound quality, it's difficult to say. I've heard the Saba green cones, and thought they were okay at best - modern drivers are far superior IMO.

My recommendation would be simply to give them a try. If they make you happy, that's fine by me.

Thank you very much, Chris.

I tried a Lorenz-Blaupunkt 1939 field coil as mid once. If I've had two of them they would still be in my system!
Try them!

Thank you!
But is it possible these old fullrange from the '50 can handle just 2 or 3 watt ?confused:
Regards

Yeah, they'll be fine. Probably okay up to 10w. Music is peaky anyway, so the amplifiers only hit maximum output for very short time periods - like on the snare drum.

Use a cap to protect them from deep bass.

Given the modest tube output power a radios of those days had, those speakers (also including Saba greencones and the like) were designed to be as loud as possible, not to be as linear as possible. In terms of speaker R&D we're generations ahead of them today. I'd toss them if you don't own the related radio.
Best regards!
