@patq2 we really would like to/are trying to help you.
You're talking about this?
If so, this is a very specialized driver designed for reproduction of low frequencies, including a built in amplifier and crossover network to use it as a so-called subwoofer. The subwoofer system is incapable of much midrange reproduction at all, and even the driver, if removed from the subwoofer and repurposed, will have very poor frequency response extension.

If you want to build a useful two-way loudspeaker system with a 10 inch woofer and a tweeter, and if the SEAS "A26" I mentioned earlier is too pricey for you, take a look at the forum and projects on PartsExpress website.

You may find some good ideas based on some of Parts Express's own inexpensive drivers (e.g., the "Goldwood" line).

The Skar tweeter appears to be this one(?):

This "one inch" horn tweeter is sold under many different names, e.g., the Pyle PDBT28:

https://www.parts-express.com/Pyle-PDBT28-Titanium-Tweeter-272-115?quantity=1 (currently out of stock)

I couldn't find a frequency response curve for either of the above, but here is another very similar tweeter from Parts Express with very similar specs.

and here's the frequency response curve:

The nominal frequency response (per the website) is 2000 Hz to 20,000 Hz, but the response is only kind of flat from about 6 kHz up to about 16 kHz (rising on-axis response up to about 18 kHz).

Where the hell is that very specific 1970 Hz from anyway? I can’t find any references anywhere for it? What value cap is it?

This not that far off the thought process of high-end audio speaker designers that "tune by ear". "I like what this driver is doing and I like what driver is doing.. let's just combine them and it'll be awesome!"

What crossover point were you using again? Did you stuff both these drivers in one cabinet? How? Where? What?

And also, pictures or it didn't happen. :)

If I were Andrew Jones this is probably how I would do it. But I'm not.

I have so many questions. First one being, "why?"

That's not how that works for a multitude of reasons. That's more than two octaves different.
well I really like how 1970 hertz sounds on my 10 inch speaker so it must be working

I only have one 10 inch woofer so the sound is MONO up to 1970 Herts my tweeters is stereo

Looking at our Worst Measuring Speakers thread, "awesome" means designed by a 10 year-old.

Not really, for a variety of reasons. Sub drivers generally don't extend very high in response because the design requirements for lots of low frequency energy run pretty counter to extending up into the midrange much.

I, uh. What?

I suspect that I would find this arrangement to sound awful. It would also measure very badly. There must be something else doing midrange work, otherwise vocals would be very quiet.

My guess is that trolls lack midrange sensitivity:
