Waves???
Hi again!
No waves for us out here - just helicopters between platforms on Ekofisk/Eldfisk field. Maintenance and keeping up old telecom-system. But 4 week off at home is a fairly good deal - gives one time to keep some good sounding speakers up to date.
FullRange is perfect(and Alp10.2 is nr1 - and FR125Sr a little juvel)
Greatings All!

Now - The pics!!
Hi John!
Home from platform and playing some music. Roger Waters - Amused to Death!!
The soundscape is so transparent and at times I must turn down the volume because I`m afraid the bass is too much(it`s not - the 10.2 is fairly well broken in now!) - but if after a long silent spacey tune - and the bass turns HEAVY! Then it gets spooky! And just more so on Three Wishes!!
But to the point: the picture is of the plate over the sticks and I think it is about 120 mm long, but I made an additional 25 mm long plate so the lenght is about 145 mm + the hole in the front which is 18 mm= 163 mm! This is not exact, but I`m gonna make some arrangement inside my speakers 1 day next week so I can give you a more exact number then!
Best to all!!

Alp10 Gen1???
Hi John!
I`m not sure if my 17 liter box will fit the Generation 10.1 exactly - I really doubt it will do fit. The ports will mostly fit - but the internal volume i think will be too big!
I would rather go (with Alp10.1) for an internal volume around 13-14 liter. The parameters and what Mark(MarkAudio) and Dave (Planet10)has proposed is more around these results.
But you decide for yourself - and the result can be satisfiying! My own trying both on Fonken with FR125SR and my last build teached me that the fun is in the process/searching and the result is ALWAYS a teaching for good or for (sometime) not so good. BUT I was VERY lucky with my buildings, and we as humans are not always this happy with our findings in life!!
Good luck with your project.

The Mar-Ken10 for the Gen 1 A10 is free. p10 hifi | Box Library / Mark Audio. These could be adapted for over-under vents.
I think that my (mistaken) thinking that A10.2 would not be happy in this large a box, came from sims for the A10.1

last fix
Hi all!
Had a(I think)last inside fix on my 10.2 to see - if there was something more that could be done to strighten bass or other things with the sound.
The sound is so good already - so wasn`t expecting much to be honest!!
Started with glueing some more felt on a couple places where there was some open holes, and got some more permanent screws to the back plate!
The I sat down with the Stereophile TestCD : And started listening first to the Phase and some more before I turned to the basstest-section: And it all went well - first 100Hz, then 63, then 50, then 40, then 31,5(weak-but still), AND then 25(like a whisper).
So I tuned it to somewhere around 35-40Hz - and it gives output down to low 30 Hz. So making the backplate airtight really helps the bass in this PERFECT driver in this small box
So all this in a 17liter Ported Homemade Speaker: 30 Hz to over 20000 Hz and with a soundscape that is startling!
Greatings to all.

Some more...
Hi!
The following is a post that I made on the Class D:
Hi there all!
This is my first go in the amp-building appartment! A SDS254Kit. It is just running its first go with some music this week - and 1 impression is - that it is just as good as my 2 year old HK980 - if not even more revealing. A little weak in the bass, but will change the electrolytic caps to some better/bigger later - in a box that is more accepting for this! A very good soundstage with my Alpair10.2 when I use the pre-amp in the Harman. Even straight from the Touch with some 24/96 music from BowersWilkins Music Club is very good(need some better DA-converter than my old DagMagic to fully unlock this possibility.
Next step - build a Nelson B1 Passive Buffer(some additional tricks from some of you guy out there as help for this build?).
And after some time with the Alpair the impression is: the Soundscape is tremendous and it fills my big living room. When I listen to Herbie Hancock in his translation of Don`t Give Up(Peter Gabriel cover) on the Imagine Project it is like the piano is in the room. And even if I don`t like jazz(this album deserves a place in our hobby with it`s genre-crossing world/rock/jazz/blues sound) - it really gives me pleasure to listen to it: And Hancock has some Tetra 606 Open Baffle speakers in his home - so the groundwork should be exellent - tetra 606
And after that a F4-F5 amp - maybe? And maybe an Alpair12.2 MAOP? If time and Spirit allows!!
Building has never been so fun since I build an Hafler Pre-amp and a Sentec Power-amp in the 80s!
