Seeing as I will be coating the entire interior surface of the speaker I picked up some acrylic floor wax. (The small bottles weren't going to cut it) A quick spray of polyurethane in a can... (the plaster rectangles might not take to kindly to being slathered in floor polish.) and we should be off to the races. This is the same stuff made by Johnson that the guys use on the model airplane forums. Click the image to open in full size.
Have started assembling...

Hey Bud,

Is this stuff the same as the micro gloss?

Honestly, I don't know Alex.

Many years ago ,when I contacted Micro Scale about buying quantities they indicated that the Gloss was an industrial strength acrylic floor wax, that they purchased in 55 gallon drums. I did not ask who made it at the time.

They are more closed mouth about it now. There has been a change in chemistry, about 10 years ago. I still have some of the earlier material and of course some of the current also. When I used a lot of the material, the earlier product sounded slightly better and seemed physically more flexible.

To find out, all you really need are a pair of silk dome tweeters, as cheap as possible.

Bud

Can you elaborate, Bud?

Silk dome tweeters are very susceptible to EnABL and Micro Gloss. A stiffer material will raise output and may introduce obvious FR peaks. A softer material does less damage.. So, if the material under question matches the Micro Scale Gloss in performance change, then it is for all intents the same material. Easier and cheaper than messing with wider range drivers.

Hi Bud and Alex, just to say that the cabs are up and running...

In a word, *very* articulate... lots of low level information on recordings that I have never picked up before.
I posted pics here:
Terry Cain's BIB -why does it work and does anyone have those Fostex Craft Handbooks?

But this gives you a general idea of what the cab looked like before being sealed up.

I will post listening impressions later.
Thank you for all of your sage advice.

Next on the list of things to do, enable the speaker and then the outer baffle.

Looking forward to what further tweaking will bring.

Andre,
Congratulations on being up and running! Wish I could hear them. Do you have a Zoom recorder to post mp3 clip of your speaker in action?
Btw, are you using stuffing inside or leaving it just with the Enable treatment? Seems like stuffing, it touching the treatment would render it useless.
Regards,
X

G'day andré,

Great work. Love the photo's!
The treatment on the outside will really bring it all together.
Looking forward to your listening impressions.

Cheers,

Alex

Unfortunately I don't have a zoom recorder, I could record it with my camera but the mic is nowhere near as good. Listening impressions are posted over in the regular thread here:Terry Cain's BIB -why does it work and does anyone have those Fostex Craft Handbooks?
