So what accounts for this improvement ? I am putting it down as an improvement not a difference.
The little wooden cubes I had the four teeters in before were put together in a hurry out of rough scraps of chipboard. None of the edges were rounded over and they were just plonked on top of a piece of cardboard with the same footprint.
So I think the rounded over shape of the dice shaped pod is having an effect with regards to less diffraction. But the material the tweeter pod is made of has changed as well so I am clutching at straws but from what I know about speakers they seem to be the obvious reasons. The pod is in exactly the same place that it was before.
So is the foam having a good effect ? Don't know. All I know is the improvement it has made as a whole. It could be the foam transferring less vibration to the tweeters. Also the up firing mid bass might not be reflecting off it as much and some of the bass can travel through the foam of the tweeter pod. I was worried before doing this that the foam dice would not be rigid enough and that the tweeters would be able to move. I don't think that this is happening, there isn't any smearing. It has in fact tightened things up
I had cut the hole for the tweeters a while ago with a hole saw which was slightly too small in diameter. When I pushed the tweeters in they stayed where they were because the foam was gripping around them. I didn't even have to cut a notch out for the lead out terminals
They still haven't moved but I am thinking of some way of having hollow wooden connecting rods between the two opposing tweeters and screwing into them at both sides. The top and front tweeters would need either connecting rods to screw in to that connect to wooden discs on the opposing side or some way of attaching them to the rods that connect the two side firing tweeters.
I am very happy with the way things have worked out so far with these foam dice shaped tweeter pods. I kind of like the contrast between the black of the tweeter and the white of the dice. I will probably end up making it all black though as to not draw too much attention to it. then need to think of some way to stop little fingers pushing the fabric domes in
