MK Pluvia or WB BetsyK

[cygnus x1]

Hi All,
I'm building a living room spk, 1cuft, vented and am considering the Pluvia or Betsy K? I think the posted response for the Betsy K is smoothed? I like MK ( I have 10p in my main system) and would jump on the Pluvia if it was not a metal cone. I never been able to get past what metal cones do to string instruments ( especially cello). So looking for recommendations. Anyone have a real Betsy K response graph? Any other "cheap" driver I should consider. Had Fostex FE167e at one time...liked them but no longer made (maybe FE166nv).

Why not Alpair CHP-90?
Or Alpair 10.2Maop?

2 very different drivers. Have had both, would not chose either. Don’t know about the WB but 2 litrs is too large for a reflex for the P11.

+1 for chp90

Which Pluvia in particular are you referring to?

 

[cygnus x1]

Pluvia 11 (Dave, you say ported 1cuft to large?). The CHP90 looks good on specs? Recommended port size for 1cuft box? I have the box built, Has removable front and rear baffles, so I can change as required? I have a duotone 7" in it now, but no base to speak of.

We put it in 9 litre. Larger the alignments start getting worse & worse.

If you want a big encosure FHXL or Pensil.

I have not looked at the CHP-90 yet.

Last question. Anyone try the SB Acoustics SB20FRPC30-8? They would fit the cutout I already have and they list a ported 1cuft box alignment (Madisound). I'm using an old photocopied graph from a Weem's article. Not sure if the port data is correct.
