FWIW, I just use the 'report post' [red triangle] to ask mods for whatever help and so far, it gets done PDQ.

I can’t download the shared plans as Google+ has ceased. Where else can I get them? Am interested in the Karlsonator 8. TIA.
The 0.53x Karlsonator with dual 3FE25-16 or dual TC9FD or single PA130-8 is a very nice speaker. You will enjoy it and it’s not too big. Can be used in a variety of places.
Hi X - - Karlsonator12 is tuned to ~37Hz, Karlsonator8, 41Hz, and Karlsonator6, ~60Hz IIRC.
What might be a good Karlsontoar for FE206EN to get good punch and low cone excursion? I'm asking as theres a query on what would be good K-wise for FE206EN (and that I don't have a Karlsonator8 to test). K12 tune ~63Hz and offer good punch for FE206EN.
Also, I'm interested in a Karlsonator "10" size and woujld be happy with a solid 60Hz output. Beta10cx might not have enough resolution - perhaps a different lowpass would help a bit.

If it is anything like FE203EN, then I did a sim a while back here:
Mini Karlsonator (0.53X) with Dual TC9FD's
Mini Karlsonator (0.53X) with Dual TC9FD's
FE206EN might not slump as much ? Concerning a K aperture starting gap, how wide would you set it in this case when using a 12" speaker?
This thing might help sort whether fudge modeling can pick a stub or not. I hope it somehow works with some 10
and 8".
A notched shelf vent XKi might be a good thing.

hey X - do you have recommendations for a mini Karlsonator for 3" -4" that is really tiny but still functional ?
Yes, the 0.40x scale in 3FE25 or TC9FD. I believe you have a pair already (I gave you a few years ago). How do they sound?
That’s already 3.5in - maybe a set with 2in SB65WBAC25-4 might sound ok. Low SPL sensitivity though.
I think wood sounds fine, in fact maybe better bass response from stiffer construction. A buddy at work has a set and I think they sounded fantastic.
Wood needs careful foam sound dampening or may sound echoey. With the foam pads, sounds great. I’m not sure if bass is better though - foam sometimes can be a re-radiator of bass.

X ---- wonder if a little K-cavity/lens could be used as a tweeter/helper tweeter. Look at the 120 degree dispersion I got with a cheap "phenolic-ring" tweeter.
The cavity was wedge shape - like a regular K

Hello everyone! I will build kardsonator 8 for fostex fe206en. The question arose: in the original cabinet there are cuts (pic 1), in kardsonator 8 there are no such slots, tell me if cuts are needed in kardssonator 8 with the fostex fe206en driver? How many slots and what sizes? thanks

Karlsonator is a different speaker alignment than original K15 style speaker. K15 from 1955 and its scaled variants are 8th order bandpass speakers with a K aperture acoustic lens.
The Karlsonator is a folded 1/4-wave mass loaded TL with a K aperture lens. It can be scaled and tuned much more effectively than the K15, which cannot be scaled below 12in relow. Smaller sizes have a much higher box tuning.
So Karlosnator does not have any slots, it has a TL vent at the top behind the K aperture.

Thank you so much for your answer. It's clear to me now. Can you give me some advice on how to dampen the hull? As well as for bg-20 (as shown in the photos on Facebook)?
