Hi Ed & all,

I bought a pair of Lii F15 drivers last year, my idea being to place them into a Karlson enclosure....crazy I know, but I have done it.
I first built rapidly a pair of OB and tried different sizes, OK, fine, but not what I was after.
So just before the lockdown, I bought for 150€ of wood (purposely shitty osb), glue and so forth.
Then as usual, I started to build big Karlsonator boxes on my kitchen table with my own drawings as there was no Karlsonator of this size I know of.
Tonight is my first listening. God sake, nothing much to change, I may try different small modifications but as it is now....big sound at low level with plenty details just as expected.
As to being able to modify, I do not even close the boxes, I hold the panels with tape and it sound so good.
The placement is never critical with the Ks.
I run them with a FirstWatt F5 and a Shiit Sys.
Ed, remember I sent you all about these speakers you really should look into it.

Here are some pictures.
It is far from being finished, I leave the top and back unsealed to make eventual modification.
This type of material is the worse to work with, the planks were not flat because of bad storage and give a lot of sealing problems.
But it is cheap, and nearly the only thing available here if I can say because for that 2.2cm thickness I waited 2 months, but the most important it is heterogeneous which is very important to avoiding internal standing waves.
I hate damping which muffle the sound, here there is none.
All this is made on my kitchen table for the happyness of my wife.

Tooppy that’s one of my favorite mockup materials too. Please keep posting about the Ks.

I keep listening ....
After few trials of inside partitions etc...I have a pretty good idea of where things matter.
A single driver, so no crossover, no damping, for 150€ of wood, glue, screws + the drivers I have a fantastic pair of speakers.
I am going to spend a bit more on plexi and nice bolts to make them look nice.
For speakers, my quest for the Graal is over.
A friend of mine has spent big bucks on a system, I pity him !
Now I should look into the source of my system.
Anyone here have use a Bugle 3 phono preamp ?
