That is an option, but then you can see the glue true the grill..

That's not a problem if the foam is in front of the grill, but it is a problem if it's behind the grill...

Any tips or tricks?

I haven't tried this but I've seen recommendations on other fora to spray the glue on the foam first (not the grille), wait a minute or two so the glue is less liquid, then press it onto the grille.

Around 250,-  (for 2) including taxes and shipping. 
Main thing is that they have to be drawn in a CAD program of some sort (which just cost time).

So had some contect with the company that all bass tipped me, and gave them al the measurements.
It is definately not cheap, but it is a must for me LOL.

I'm thinking of mounting the grill on the top woth some strong magnets or something. 
Any thoughts?

Did a gig last month with two TH18 + the mid/highs, and it sounded pretty good (but not good enough LOL). Response was pretty flat, except <100 Hz, because I like some extra low. Output of the overall system was nice!

The drivers in the TH18 will be replaced with the 4 Ohm 18sw115, because now I have a PL380.
Also bought a PL340 for the 12NW76, I only need a 1he amp for the DE800's.

I know that one of the goals for the TH-18 was to reach 100 Hz, but at full output, my own mid/highs lack a bit of low. Just the 80 to 100 Hz punch isn't there (att the max of the system). 

I also need a smaller cab for the smaller gigs, sure I can build a random cabinet, but it would be nice if the hole system could be used together. 
Just a single 15" reflex is still an option, tuned at 40 ish Hz or so.

" don't even know where the Cubo comment comes from?"

The Cubo designs all have much worse peaks near the upper end of the passband, yet no one complains about them.

They are similar to the topic box.

Do you not own an EQ?

I don't even know where the Cubo comment comes from? Nothing wrong with Cubos - I even helped draw up the Cubo Sub plans...
When I designed the TH18 I was trying to aim for an extended mid response, to make it easier to match different mid top cabinets.
Regardless not many builders seen to run them above 100hz anyway, which means that some mid tops are struggling to match them. Smitske said he was trying to design some cabs to fit on top of the TH18 boxes and maybe only for the mid highs - Depending on the bandwidth he wanted, I don't see the sense in designing a cab that would have a peak in the top of the passband it was being used in and having to EQ it back out.

Do I own an EQ?
Well I have an well sorted Ecler Sclat 100 for DJ use.
A Soundcraft UI 24R is my current live sound mixer, and a I run a tweaked DCX2496 on my PA.  Is that enough EQ for you?
