Hi Guys. I've been laying low for a while now but ready to start experimenting again. I got these four mid/woofs and two tweekers plus their crossovers the other day and looking to put them in something. The mid/woofs are 3" and the tweets are 1". I was thinking about a scaled down Karlson but don't know how to size it. I assumed the tweet would go right above the slot. Any thoughts?

No X, right around that time, personal matters popped up that are just now settled. I haven't sat and listened to my big system since then either. THis project will mark my return!!! These drivers and xovers are from a Visio Sound Bar. I was supprised at the quality actually. I'll get them measured up Sunday and post the results. Do I need to find the Vas as well???
Yes, the Vas is needed - use the added weight (modeling clay or coins of known weight) trick.
So that is what is inside a $100 Vizio sound bar? Those things sound good, I am amazed when listening to them at Costco. What is even cooler is they have a built in amp and SPDIF input. Sometimes I wonder why we don't use these as MP3 player "Boomsticks"?

Hi X, got the little buggers all measure up. Here is the WT3 screenshot. Impressive little guys but I hope they will be right for the Karlson. I have a pair of Paradigm MK 3s for my computer system. These Ks will replace those, so that is my target sound to beat.

I think that using these as dual drivers (series for 8 ohms) can work well. Just add the stock tweeter at the top above the narrow slot area. Use the supplied XO and you should be golden. There is quite a bit of bass gain so BSC should not be an issue. The sim assumes they are 12 in away from a back wall and sitting on floor. The scaled size is 0.47x tall & deep, 0.35x wide. Make the K-aperture come to a slot as usual (not a cusp). I hope you will build them, they look like they should sound good.

That all looks great X. Sorry for my ignorance, but .47x of what? I looked through this whole thread because I remember reading and seeing the stock dimensions that the scaling is based on, but I can't find it.
We have a SMAC (southeast michigan audio club) meeting at the end of the month and I'd like to get them done by then so they can be auditioned by the group.

The scaling is relative to GregB's original Karlsonator 12. You can find that posted somewhere in this forum by GregB - in Karlsonator thread proper.
Here is plan for Karlaonator.

Here is the Karlsonator thread.
The last link in the first post is the drawing for the original (12") Karlsonator.

You sure those aren't from Transylvania?? 😉
I think of this style of enclosure as a folded open baffle, if that makes sense.

the color scheme is dead-on😀 - did you see what I bumped into from a 2007 Ru thread? Carl might like this if it had a curved

also, they ain't chicken to do other good stuff

An externally hosted image should be here but it was not working when we last tested it.

They look stunning but also photoshopped. I can't see what is on top. Is that where the driver goes and a port underneath it or a tweeter?
That K-aperture goes up way too high - the effective length of that TL is essentially maybe 60% of the length, so not much bass to speak of. It is more as GregB said more like an OB. I like the Count Dracula cape look though.
hey X - what do you think of this one?
It's kind of like GregB's Karlsonator but with a shorter stub cavity above the driver. No way to tell unless I modeled the geometry - which, is kind of a pain. Unless you intend to build one and need me to check with a sim first, I will say it is probably close to K'nator... and call it a day. 🙂
