Guido,

No, you are right. But the ripoles that Rudolf designed for me have resonance at 300hz and i will cross around 200. Yeah, the filters will be steep and for sure in digital. If they can work well, your enclosure design could be my definitive one

Keep me posted about those and soon enough the first real panels should be ready...

As said in the other thread i ditched the Ripole option, but i'm still considering the 2x10" in a setup like the Diamonds.

I dont remember when i updated you on my Hemps, anyway, in the current baffles (20mm plywood, simulated trapezoid shape), they behave much better than my ears would tell me.
I did some measurements and more are to be done. So far, they are pretty smooth!
the aNoyance in the voice range must be only energy storage. i dont know exactly how this hapens but i know for sure now that is something that i hate.
Also i hate non linear distortions, in particular the ones that raise dramatically playing louder. My woofers are able to sustain way more power than the Hemps. I think this is a problem of most fullranges, esp. the ones with low Xmax.

Correct me if i'm wrong, but i think that the cause is the bicone, which is just paper and therefore limits the hemp benefits to <2k. Way too low. Anyway, they go really high. the rolloff starts at 17.5k and is smooth. figures, i reduced other 2db at 20k, which helps with my current source that is not state of the art.

Still thinking of replacements, not much in a hurry. Researching and planning. I know i'll stick with dipole and a widerange of some kind, with or without a (passive) tweeter on top. Heils are currently my favourites.

Anyway, I'm gathering experience. I need more and more auditions before finding "my way".

Cheers,
Guido
