Much better to use closed boxes for tops.
Only thing is if you're going to feed them several hundreds of watts continously (certainly not me) it's nice to have some cooling.

Yes. I plan to use them for PA/parties/outdoor also that's why I came up with the idea to go ported because of cooling. On the other hand SQ will suffer. Crossed over at 120Hz they should survive quite a bit on continous high power (250W) hopefully.
its a reaonalby tough driver and IIRC would take around 15V at 20Hz in free air without hitting the back plate. I might put it back into a Karlsonator12 (fb ~37Hz) and see how much upper bass peaking really occurs.
What`s the deal with the Karlson enclosures? I saw a lot of projects on this site. Google brings up a lot of mixed reviews.
Regarding the Fane I measured and EQ'd it flat which was kind of boring, then suit to taste which was very nice although kind of boring also.
Then I switched the EQ off and now it is far from linear or ideal but somehow I like it better.
So after 3 days of heavy EQing I went back to no EQ at all. Sounds more "natural" to me.

Yes, I agree.
Heavy eq sounds "lifeless" somehow, no eq sounds really dynamic and "live".
I am still experimenting to try and find the best median, a little bit of padding down goes a long way, but you still miss some of the transient response on snare/unfiltered kick/high tom/707 or 808 with hard kick (where the first part of the sound is a completely vertical spike).

Most of Karlson's original claims were obviously bogus, but when you look at it from a BP6/8 angle (which most K's are), it's design becomes more obvious and something quite usable can be made for generally low-Qt drivers. The one thing that separates it from normal bandpass enclosures, mostly in how it's used, is that the front radiation of the driver is used above the enclosure gain bandwidth, into the midrange and sometimes fullrange. This is where it mostly can go wrong sonically.
Karlson fans used to have their own forum, as well as the old Fullrangedriver.com site, but most have moved here, in addition to renewed interest with XRK971's Akabak model and smaller format modern designs derived thereof.
I agree with the above recommendations to keep the 12-250TC in closed enclosures, it's Qt is a bit on the high side for vented of any sort IMO.

Thanks for the explanation.
I use BP6 for subs only.
From the design I figured the Karlson might be something like a "wide-band port" kind of "thing".
Yes. SQ will suffer substantially. I am aware of that.

thist hread has been awfully quiet recently.....
I saw someone asking in the ENabl thread if anyone has tried enabling 12-250tcs, and thought, why not ask here.... 😀

Where was that phase plug measurement again? So certain I've seen either the Fane or Eminence 12" with/without plug graphs somewhere!
Considering cutting up my 15", just want to have some slight bit of information about it first.

Is that for the 12-250TC driver or? This thread has kind of gone all over the place talking about differing drivers other than the main topic driver is why I ask? Thanks

Please post pictures of your phase plug. I`m using a 15 inch Fane and would like to see what you have done.

Finished some 78L sealed cabs today for my set of 12-250-TCs. At the moment, they are just bare ply; I'll veneer them further down the line:
They sound great.
These Fanes really are super full-rangers.

OK, a few early observations.
The rising response as seen on the published FR plot, is of no consequence in a real room situation. Angling the speakers to fire straight ahead in combination with half space placement deals with it nicely.
In hi-fi terms, coloration is low; remarkably low for a full-range driver, the presentation is nice and smooth overall and bass is quick, agile and even, though ultimate extension is lacking. They might go a bit lower as the suspension breaks in; other full-rangers develop more bottom end as they run in, so I don't expect this one to be any different.
Vocals are very very good, as are saxes, strings, brass, electric guitar and Hammond organ. A relaxing listen, free from wince inducing moments.
But......it's at the top end where these drivers show their fabulousness. How the hell do they get so high and so clean?
