2 DR250 build - Europe Materials

And on it goes, backsides glued with a million screws per inch to have it sealed :)

Hf horn in place, a bit messy with the glue but i'll scrape that off later.

Now again waiting time

Slooowly but steady :)

One question to the hf mounts:
When rotated (right) there is no space left for the screwheads.
When straight (left) only two can be screwed.

I could drill the horn away a bit for the screwhead, but will it work when just 2 screws holt the cd in place?
The cd is the lavoce, gasket tape is directly around the 1 inch exit.
Which way to go?

Edit: This is what the CD looks like:

The HF mount question derives from the point that the other options are just with two screwholes, as the asd1001 for example:

Sure the plan says it is sufficient with two screws; but is this valid for the CD with four screws as well?
Don't want to have anything rattle or come loose..the weight and dimensions seem to be very close to each other (0,9 kg each), so i assume the 2 point mounting should be okay?
Would it be worth it to replace the gasket ring with a full covering of the area? Or just put it on there as is?

I think your intuition on this is going to be better than anything we can offer, being as you have it in front of you. Seems the only two reasonable options are to either use two bolts to secure the driver or put the adapter on at 45° and create bolthead clearance by carving away a bit of the sheath. You got this. I'll be curious to see what you choose to do. For what it's worth, you can lift a car engine with two bolts of that size, it should be sufficient to hold the driver in place and create a sufficient seal. If the adapter were a less robust plastic, I might suggest four bolts to minimize adapter warping causing a leak. But, it should be plenty okay into half inch ply at that distance between fasteners.

My NSD2005 CDs are attached with two bolts. Never a problem. I would use lock washers, though.

[Marflinger]

Good idea with the washer; not sure if i find a matching screw, but i will look for it.

Intuition yeah, not sure about that in this case, as i have no experience on what matters or what fails first. Done (crappy) subwoofers before, thats it.
But then i think i will go for 2 screws, as the plate is not wobbly plastic (which would be a pretty good reason for four screws) it will work i think.

Maybe the weekend lets me get stuff done further, components for xo arrived as well.
Thought about the handles, will update to this as soon as i can show my thoughts on pictures.

But thanks again for the replys!
