Would like to know more analog crossovers similar to Fostex EN3000 and EN3020


I would like to know more analog crossovers similar to this models from Fostex, EN3000 and EN3020, EN3000 appears regularly to sell in Japan, the more sophisticated one EN3020 it's much more hard to find...

Anyway, would like to know more units with similar characteristics like this ones, very straight forward 3 way, easy to use.

For those who not know this Fostex, here they are:

EN3000: https://www.hifido.co.jp/sold/14-84210-27250-00.html
EN3020: https://www.hifido.co.jp/sold/11-62786-28291-00.html?LNG=E

Thanks.

No DSP's recommendations please.

cosmicjazz is intended to DIY a pair of 3 way horn Fostex speakers using active crossover :

Look like the recommended passive crossover is 6dB/octave on high and 12dB/octave on low.
