Planet's recommended connectors are the ones I ordered from PE without knowing they were a favorite for the uFonken. When I saw them the other night, they just made sense. Direct wiring a uFonken sounds like common sense, but I will take these speakers to other places, and because wire runs are not always the same I rather have connectors.

For those of you interested in good quality binding posts for larger speaker projects, PE has a buyout sale of Mirage speakers cups with three different post options. One has isolated binding posts, the other has nickel plated posts, and the other has gold coated posts. I have had lots of experience with elector nickel plated (ENP) actuators, and they are very non-corrosive.

Note that Xmax is only 0.5 mm. It is not able to move much air...

The micro Onken design I have is well suited for near field desktop use as it is fairly compact. the dimensions are 5 in wide x 8 in deep x 10 in tall box (6.5 liters) with qnty 6 vents that are 0.1875 in wide x 1.5 in tall x 5.6 in long. The 3/16 in (0.1875 in) vent width is chosen for thickness of foam core. Note that this produces a box with a vent cross sectional area of only about 33% of the driver Sd vs typical 90% Sd used in Onken design. Had to do that to get a reasonable length for the ports. The calculated f3 is 55 Hz - as good as what I get with a 30 in long MLTL using this driver. What do you think? Worth trying?
Planet10,
When you designed the uFonken, were you able to follow the Onken design guideline of trying to maintain vent csa of 90% of Sd? Or is that not really necessary? I am just unable to get anything like that when using the Onken calculator even with FF85WK. Anyhow let me know if my TC9FD Onken design seems reasonable.
Thanks

They're not Onkens. They just look like them. In reality, the alignment is heading in almost the reverse direction to the traditional BR / Jensen Ultraflex / Onken where the object is to use the massive vent system to provide maximum efficiency at Fb. Dave is using the friction of high aspect ratio vents to provide a near-aperiodic alignment.

I sort of guessed this was what was going on as I get similar results when plugging same volume and vent dimensions into WinISD. Does the high aspect ratio vent provide a smoother response into the upper-bass and midrange? I guess this could be modeled in MJK to see closer approximation of response vs what is shown in WinISD.
