Looking for BG RD75 substitute

[ABJensen]

No why should I ?. I have provided a link showing their simple construction. And I claim that my diy ribbon sound better than the BG 50.

I’m not sure if this is still relevant but, I’ve seen B&G type planners on Alibaba.com, recently.
Hope this helps someone.

Did you look at the measurements?

The response is all over the place and the 2nd harmonic has peaks of up to 5%, even the 5th has a peak close to 1% and this at a level of 85dBSPL (I assume at 1m).

looks indeed like an error, even then 2e order is not that interesting still there are peaks of 2% in the third to..... not to great
