Does anyone know this speaker?

Hi guys, does anyone recognise this speaker?

That implies you know what it is so why the hell are you asking?

I can tell you one thing though: It has a whizzer cone and therefore is the work of the devil. 😀

ok, let me explain: someone's offering me a pair of speakers (to buy), it seems to be a transmission line, the port is on the bottom - it seems to be a DIY build from Sweden. It is located about 100km from me. I am wondering if it is worth the efforts 🙂

The cheap piezo tweeter does not inspire confidence!

It would appear that any value would be in the enclosure and that would seriously need inspection.

Ask the seller to remove drivers and rear of enclosure (if applicable) and send more photos.
 
Well ... it might be Philips 9710 in ferrite magnet version - here is a link to compare picture: FS: 2 pairs of Philips 9710 full range , or this - Vintage Philips full range 21cm AD9710/M8 stereo pair very good condition | eBay ... by the way the pattern you see there on the cone is most likely from sun light + a screen (the colour is gone from UV exposure).
Other than that I don't know of any other full range speaker with a full cone (concave center, the cone is one piece, not cut at the juncture with coil former)
