Thanks Ian, will probably need to get what can be handled in the shortest time. Subs need to be completed before the end of the month.

2K dries very fast, but can not be brushed.  You will need to spray it.

Definitely spraying yes. Will the paint/hardware stores stock that matting paste?

You will not be able to get 2K at a hardware store, or you run of the mill paint store.  You will need to go to a specialist automotive paint place, and they will have the matting paste.  If you have difficulty finding it, let me know - I have 5l of the stuff here.  Can always scoop some out for you.

Thanks will try to find some first. If I use satin black enamel will it be easier to get the finish I want? I imagine using the matting paste with 2K would require some trial and error to get the ratios right.

Just hope I can find something on Saturday morning.

I would not say so.  The problem with enamel is that it takes hours to dry.  During that time all manner of insects, dust, grass, etc will stick to your nice paint job.

2K is easy with the matting paste.  1:1 ratio for dead flat.  For satin, I would go with 100:50 ratio.

Not likely to find any auto paint places open on a Sat morning tho - they mainly do business with companies, so not much need for them to be open over the weekends.

Is your paint prep 100% done?  Perfectly smooth, primer applied, etc?

This project was dormant for many months but I did resume it again in the December holidays and finally completed the subs today.


I sanded the wood then applied pink wood primer. Then sanded the primer. Here are the pieces after grey automotive primer was applied.
          



Then a coat of satin black 2K ( this my dad sprayed for me).
     


I'm really glad someone started the thread about think-pink vs isotherm. After that discussion I went and bought Ecotherm. Here the top section of the tubes have been lined and I'm just about to insert the top endcaps.
    


And this is why I'm so happy about the think-pink discussion! I had to crawl through the tubes to seal the top caps with silicone. If it had been lined with think-pink that would have been terrible.



Here the 160mm OD, 1 meter long ports have been installed with the internal brace providing support (and flares) to the port tubes.
     


Anton (NoSnipeLimit) applied epoxy to the t-nuts while I was gluing in the insulation in the above image. There is a gap between the port flares and the damping material to allow the ports to breath freely.

Bottom end-cap installed



View of top-cap with port tubes installed



Speakon connector installed



Driver bolted in


Base attached with 4 long bolts made from threaded rod with grippy rubber feet glued on.



The leg posts where provided verniet by Oradba69  :)



Some shots of the completed subs at Anton's place.
         


Response measurement at Anton's:

Really smooth and a natural house curve without any EQ at all. (Includes speakers, xo @ 80Hz)

The subs sound great and have plenty of power. I'm very pleased with the end results  ;D



I would like to thank everyone who assisted me with this build!
