edit: Haste + fading memory makes waste!
In retrospect + Googling, this appears to be the 'C' model drawing, so includes the ~full size cutout bottom 'baffle' + separate reflex tuning panel, with the original having the 825's two piece baffle boards and the 'B' as shown here: http://www.lansingheritage.org/images/altec/catalogs/1975-mi/page12.jpgGM

well no sure that glass dust is good for loudspeaker's membrane or coil. I will surely choose alternative even cheeseclotheIt's dangerous for humans, not speakers
Is there a "break in" period for NOS speakers ?
I prefer them over TMM with 500 Hz XO as well as dual 12"/800 Hz due to closer c-t-c, better pattern control and why they're still being used in some larger recording/mastering studios, though of course at some point off axis the XO BW does begin to have audible TD.
Unfortunately, the shape keeps the big ones from being an option in most HIFI/HT apps:

Yes the port is bigger according to what I have read in translated Japanese web page so it should sound better in the bass area I do not know because I have not heard them. Better in the bass area meant that acoustic music ex jazz sounded more natural, hmm.
I have the dimensions of external dimensions width 690 × height 1,018 × depth 485mm so it does not differ much but it is the baffle that differs, guessing what dimensions the port has can be so tricky enough.
I hope our Japanese members jump in and can help so I can start planning. That I want to build these is that I like the style I can build 620 but can I clone these from the beginning so I do not have to change 620 later.

My 620 cab clones are, external dim in cm w 67 x h 102,5 x d 47. The port is 28 x 6,5 depth 1,9 (19mm MDF).
The enclosure specified for the Altec 601-8D is the 614D
The enclosure specified for the Altec 601-8D is the 614D.
I have found an Altec brochure for the 614D. But I can't find plans for the 614D. I have, however, found plans for a 614 enclosure.
What is the difference between the 614 and 614D enclosures, if any? There is a good chance that the plans are in fact the 614D, but mislabeled. I have looked through some of the old enclosure brochures I have downloaded from the internet and especially on the Lansing Heritage site and can't seem to distinguish the two.
There is very little in the user forums that I can find about the 601-8D. I have been searching on the Lansing HeritageForum, here, and AudioKarma among others. I have a pair of 601-8D's and N3000E that appear to be NOS, or at least appear to have never been mounted. They have been in a box for years now. I have some time on my hands and plenty of good plywood in the garage and would enjoy knocking these out.
Any help or advise is welcome.

Thank you, that is where I found the spec for the enclosure when I started down this road.
And, I am open to other enclosure ideas. Some threads suggest that an equivalent Altec 12", the 414A, would be an avenue for me to explore. I know enough to know that there could be substantive differences between the woofer section of the 601-8D and the 414A. I have not been able to confirm how alike or different they are yet.

Doesn't look like EV to me.
Sure looks like it to me, but found nothing about it.
