Well absolve 2525, they look great.
Probably the best looking Interface D/Sentry VI is saw on the web.
Are they Interface D or Sentry VI as the ring on the VMR was only used on the Sentry VI, where Interface D had a black metal with silver trim. But that might not be an absolute rule.
The stand is something I saw before as the listening sweet spot of the Interface D is between the ST350 and VMR is a bit low.
It will influence LF response a bit I would guess as you will have less coupling to the floor but that might be a good thing is some rooms.
My latest design will solve the listening height. It is a bit less wide as my original idea and a bit taller.
See attached. the wood in this concept is ebony/makassar.

Thanks, guys! Mine are Interface D. The VMRs look identical to my pro versions. You were keen to discover the subtle VMR differences between them. In some instances, I had to reglue where the VMR surround attaches to the plastic housing. Apparently the glue didn't survive thirty plus years on that slick plastic. Pretty easy fix though. Your designs look gorgeous, Peter! :-D

Ive got hardwood floors and the bass is great with them lifted.I do it more to get the mids and tweeters at ear level in my main seating area.
DIY Interface D
If you'd share the box dimensions of your homemade IE's I'd really appreciate it. I have been to listening to my iteration of the D for weeks now and I am blown away. I searched for a suitable woofer and the CV 12 is perfect, but if I get the proper box dimension for the woofer, I'll pick up the 12 you're using to round it out. Thanks in advance. These are awesome.

Thought I would jump in and show my EV Sentry VI's, they do look just like the D's.

Haha, they do look the same! Those look awesome. What are you using for the bottom foam, Tim? I forgot about replacing that. I'll have to check on those numbers, Hunter.

Well Tim, bot sure if I mentioned this before but I have the original hand drawn design drawings (with great exploded view) and this drawing is called Interface D/Sentry VI. So they appear to be one design,
In base they are exactly the same. It seems that originally the Sentry was not shipped with EQ, my drawing makes no difference between the two.
I have a Swiss made Interface Delta, and in some details this enclosure is diffident. It does not have the rounded bottom side of the front lower panel and the VMR is not recessed although I am not sure the US version has a recessed VMR, but my drawing shows that.
Attached a picture I grabbed from the web (copyright to its owner) when I was gathering all information I could get. This picture always puzzled me as the port is a round hole with no depth, so the tuning is really different.

This is my latest design. Not completely finished but close.
Like mentioned before; it now is the least wide as i practically possible with a 12" woofer.
Quite tall and reasonably deep. The volume is a bit larger, 130 liter instead of 111 liter of the interface D. Because my port has a bigger volume the filter is inside and I will use a bit extra bracing I expect that the nett volume will decrease a bit more than with the "D".
I would be suprised if you will find the original woofers "turnitdown"
I have no hopes of finding the original woofers, sadly. The CVs are working well, yet, I'd like to put a JBL or other pedigree in there. Any suggestions?

1. If I understand you correctly, it's not an absolute rule. My D's look exactly like his. My VMR's have the black plastic trim around them.
2. Your design looks nice and I love LOVE the finish choice!!!

Mine does have the EQ and it is a Sentry one.
Also replacement foam is available, see a previous post from me, here:

If I didn't stumbled onto the Interface Delta when I just had the VMR's and ST350s I would have bought the Beyma 12B100R.
This is most likely a better woofer than the EV but it is less loud, so needs more tweaking in the filter. It would have a -3dB response at 32Hz in the Interface D 111 liter enclosure with half the port covered.
It also needs a 2.5R in series to obtain this response but no EQ is needed. the sensitivity is about 3 dB less and that needs to be corrected in mid/high section.
Thanks. That's why I went with the CV for the experimental phase. Very efficient (93 or so db) in a ported 2 cu. ft. box. The search goes on.

Just got my latest rebuildt amps on the EV D's tonight and I have to say ive never heard the D's sound as good as they do now.The d's seem to realy like mono tube amplification and they sound incredible on my Dynaco mk iv mono blocks,but I just inserted my newly refurbished 1954 Fisher 50A triode mono amps in place of the dynacos and its lifted the speaker to another level.
