A new member of the family realized... the uMar-Ken6.2. This works with either A6.2p or A6.2m with no changes. These have the 6.2p.
These are the surrounds for a friends 5.1 system. The front row are the same, rotated sideways in a bar that fits under the TV.
They are pretty small. Even in reference to the mMar-Ken6.2 and the Frugel-Horns the pictures don't give the scale.

Fonken 125wk Build
A bit of a long story here, I went out on my own building 125wk boxes, actually built 7 boxes, not counting the pair in the pic. I tried different sizes and tuning frequencies.
The 1st pair was too small, sounded thin, jumped up a couple of liters and picked up some bass, but still not right.
I threw in the towel and contacted david@planet10-hifi.com and he had designed a Fonken for this driver (pic).
In a word Wow! Much better than anything that I came up with, a lot better; crystal clear sound, warm and throaty bass. The P10 plans were excellent, easy to follow; I did enlarge the plans full scale on a copier (recommend).
For comparison, I do have two pairs of 120FXs in different boxes; I cannot listen to all the songs on a CD, some will sound off-wall-fantastic, but others are a little sour. I do think a tube amp would help (using a sansui 7070).
This last pair is unbelievable: not an expensive build, easy to follow plans, sound fantastic - without being selective and using a transistor amp [Rotel, RB 980BX].

My Personal µFonken SET
"cooper/dusty orange" FF85wKeN installed. Beautiful, and pretty good sounding.
Bespoke, unique solid wood art builds similar to these and Bernie's Locust pair are going to be offered to those willing to pay a premium for a functional art-piece.
Bernie is working on the woofTs to match this pair, using 2 4" Peerless in a Woden designed ML-TL. They will be the same footprint and act as 32" tall stands. Will relieve the FF85 from the heavy lifting and should extend LF down to where a subwoofer(s) can be added for a truly full-range system

Hi. I just thought I'd post some pics of my finished miniOnken build.
Alpair 6P in the micro Onken enclosure (uMarKen). Sounds incredibly good, have not heard anything before this that was as controlled and finessed, even in the bass department.
Spray painting the enclosure was a PITA. My next builds will use veneer instead.

It sounds pretty much like a Mar-Kel70. Maybe not capable of quite the dissappearing act as the primes or the trapezoid stand mounts. But easier to build, high WAF (Bernie took the pictured set to his brothers on the way to their owner, and wife said, we need 2 pair, 1 pr each up & downstairs).
Chris is thinking thru flat-paks on these.

My set of floor standers is coming along. One side is ready to line with felt, braces and put the baffle on. Was any stuffing needed to stop unwanted resonances? I am a bit hesitant to seal them up without knowing. I'll try and have a listen with them clamped on first.

Hello,
Just got one side of my floor standing Mar-Kel70s together. The sound is right along Dave's description of sounding like book shelf version. I am very pleased. The baffle will remain unsealed until the second side is built so I can properly assess the stuffing.

Another pair of uFonkenSET. This time with the matching woofT.
Chris built out of plywood, with a VERY well done veneer job (each speaker is 2 pieces). This work really well with a simple PLLXO, and i am detailing a passive XO -- good at these point but i think it can be improved. Given the size of the parts if you have a spare amp, biamping will be the way to go cost wise.
