Hi Scott, Dave & anyone else who reads this.
I haven't been online here in diyaudio.com for quite awhile. I had a good almost 13 year run with the Sachiko cabinets you guys suggested and since selling them I've actually been pretty content with my Beauhorn Virtuosos. However, I just picked up a pair of these exact Diatone P610 clones with Alnico magnets as seen here:
pair 2pcs HiEND 6.5inch fullrange speakerDIATONE P610 CL0N (2019 big Alnico ) | eBay
The trouble is I have no idea what cabinets I want or should put them into. I had one man I met who was really a great guy and he suggested putting them in the Mark Audio Super Pensil 12P.P cabinets, but I have absolutely no idea if that's what I should do or if there isn't an even better enclosure one of you guys knows about that would be even better to use. What I do know is when I decided to make my first journey into the world of single wide-range drivers so many years ago now. Both you Scott and you Dave were a world of help to me by suggesting I use Sachiko cabinets for the Fostex FE206E and FE206ES-R drivers I had at that time.
I cannot help but believe you two can be the same type of help to me now. I received these drivers today and I think they're absolutely gorgeous. At the link to eBay up above, you'll see their Thiele-small parameters as well as their frequency response. I'm hoping this time instead of two separate horns whose mouths open on the front just above and below the driver. Perhaps one of you two can think of an enclosure with a single horn that opens on the rear of the cabinet. But that being said, you two are the authorities, so far be it from me to tell you what to do, I'm just expressing preferences if they can be met. Scott would these work in your Avebury cabinets?
In any event, I deeply appreciate whatever help that either you Dave or you Scott or anyone else that wishes to contribute for that matter, is willing to provide. I have a good feeling about these drivers. I just hope I'm not wrong...

Well, if the published spec. is correct, they're not particularly well-suited to the superPensil 12P design; the alignment wouldn't be great, and will have further issues if used with a high output impedance amplifier.
I haven't done anything for the various Diatone clones myself, largely because I'm never sure whether these units sold via eBay are going to be around for long, but again assuming the published data is correct, they're leaning in the direction of sealed / resistive vent loading as far as straightforward boxes go, or a relatively large TL. Mass corner is down around 150Hz with a voltage source & depending on how much loop resistance is in circuit. A large horn is technically an option, but I probably wouldn't be inclined to go to that kind of size & effort.

So Dave, what kind of sonic results were achieve with this enclosure? You know what I mean, what was their frequency response in this cabinet etc.?
Thanks, Thetubeguy1954 (Tom)
I did this in 2014:

Tom,
I have no idea how they sound. I did them for a client.
This particular Diatone (they built a ton of stuff), has long been revered. The ribbed cone & thickening of the cone material as you approach the voice coil are both intended to improve the HF dispersion. People who have them like them.
The Japanese did a test of a number of FRs, including the original Diatone 810 and the 1st Alpair 7. The A7 certainly measured better.
As you can see by the Dia-Ken, this small driver wants to be in a (relatively) big box. I will happily see if the design works for the AlNiCo version, and how it would be modified to suit. Also since this one was done, we have come up with the slightly better trapezoid versions of the miniOnkens.

Dave, I deeply appreciate your help with finding the "best" possible enclosure to use with these alnico-version of the Diatone P610 drivers. I especially like the idea of seeing what those slightly better trapezoid versions of the miniOnkens enclosures you spoke about, will look like! When you consider no matter what enclosures I end up using with the P610 drivers, they will be set-up in the same exact location as the Sachiko enclosures were set-up in, and I'm sure in comparison to those Sachiko cabinets loaded with their 8" Fostex FE206ES-R drivers, the size of these enclosures with their 6" P610 drivers will essentially be a non-issue for me. That said, I'm starting to get the feeling that these P610 drivers in the enclosures you select are going to sound very, very good indeed...
For those who care to know, my audio system:

Scott, first let me inform you I'm totally lost! I have no idea what you mean by "Mass corner is down around 150Hz" however since you mentioned possible problems if these drivers are to be used with if used with a high output impedance amplifier. I will let you know I'll be using them with my 40W/ch, Italian, Mastersound Reference 845, integrated, Parallel-SET amp.
Maybe you could provide me with a link to an example of the plans of an enclosure with resistive vent loading that you would work with these Diatone P610 clones so I could have a better understanding of what you're talking about? I don't know the differences from a bass-reflex enclosure as opposed to those that use either a circular pipe or rectangular extension from the outside hole that goes into the cabinet or resistive vent loading, hence my asking for help. In the long run, I'm looking for your suggestions/help in what I should do with these drivers...

You'll find it on the 'mail us' link on Dave's website planet_10 hifi It's at the bottom of the menu on the left.
For -3dB mass corner frequency take 2Fs/[effective]Qts once any series R in the circuit or amplifier output impedance is added in. Above that (the mass-controlled BW) the response is nominally flat, at least until resonance takes over and the driver departs from conventional oscillatory / piston motion. Notwithstanding step-loss etc., the driver only needs assistance up to the mass-corner frequency from the enclosure. Being a higher Q unit, this Diatone clone (according to the published spec., which I am a little cautious about) has a relatively low mass corner frequency.
Resistive vent loading? The box Dave shows above will provide roughly that. What is often [incorrectly] described as aperiodic, or near-aperiodic -Dave is using the friction of the high aspect ratio vents to provide resistance rather than damping material. Should work well with a driver of this type.

The difference netween a miniOnken and a typical BR is that they purposely have higher resistance vents. Taking it to extremes one gets a highly tapered TL fully stuffed to the point that the box becomes aperiodic.

probably your mail browser. We have exchanged many emails. You can also pick it off my p10-hihi website.

Dave, I tried to email you but something's wrong with my laptop because when I try to select mail us on Planet 10's website, Outlook opens which I don't use and because I don't have an account it won't show me your email address... email me @yahoo.com
