Fast, fun, Inexpensive OB project

From the top of my head down the memory lane of this thread few times here and there were mentioned about the high end roll off of TC9 as is usually the case with many wide banders. This too has been my experience. I craved for that high end sharpness.

Then I came across a video of Danny Richie (GR Research) wherein he mentioned something in the line of additional tweeter if needed can be done so facing/pointing upwards. Then started my trials with the limited parts I have on hand.

I'm far from being a crossover expert. For all my crossover works all I did was go about trying and listening after going through Introduction to designing crossovers without measurement by @AllenB

I ended up with a Dayton ND25TA crossed very high using third order. Works for me! for now. The sharp sound of the cymbals which I love/crave for is coming through. I'm loving it!

Has anyone else tried this?

I have a friend who would like some garage speakers, so I think I'll gift him a pair. I don't like selling anything, so when I find someone who has an interest in DIY speakers, I'm pretty generous. (Actually, I really need to thin my overwhelming speaker building inventory 🙂 and gifting works much better than selling), I'm not a crossover design guy. Would you be willing to share the crossover for this project using the ND25?
Thanks,
Mike

Crossover design? me neither! 🙂. I probably should mention here that what led me to implementing this was wanting to make use of few leftover parts definitely fueled by the spirit of DIY, and NOT at all because I felt there's something majorly lacking in this OB.

And since this is in the super tweeter domain I'd say it's easier to test and experiment being crossed very high. And it was fun doing so I have to admit. Hence the premise.

The top end roll off of TC9 is not noticeable in all music/recordings but indeed in some others, as in the last bit of clarity in the top end. For example I don't miss it in vocals/acoustic based music. Hence one's music taste, the source, room, hearing etc are evidently at play here.

With other tweeters I would definitely try a first or second order but with the ND25 there were some issues hence went for third order. Don't ask me how I came about with the values. After going through the earlier mentioned guide I went about 'trying' with the parts I had on hand.

Being upward facing dust WILL eventually settle on the dome and here I prefer metal over the rather sticky soft dome. Also, I rather like the sharpness of titanium dome in the top end.

If you happen to have adjustable LPAD that will make life much more easier.
