Tang Band 2145 in action

And her uncle Santa.  Where they use horns actually

Maybe put all 4 screws in to make sure you get a solid connection to your baffle.

 I actually played it thru my stereo to give it the best chance.
Not for me 
For that kind of money you can purchase a good sounding speaker from  Caintuck Audio or purchase the wild burro drivers yourself and be able to afford to use all the screws it takes to attach them to your baffle.

A much better speaker would be the KEF Ls50 which actually sounds good.

You got me.  I'm jealous of your passion and never say die  attitude. Your belief that your 40 years of some kind of involvement in audio trumps the at least 500 years of combined experience of the forum members both hobbyist and professional gives me hope . So don't give up!  If you say it  with enough conviction and repeat it enough times it will become the truth.
I don't like the sound of your speakers yet but I didn't like asparagus either but after a while my weird smelling pee made it worthwhile.

The Chinese Lil Audio drivers have gotten a lot of positive reviews.  The 15 inch is very efficient and has a very light cone so it's quite fast.  

I take it your from Flint

Let me try again.
There are poor everywhere not just in Asia. I find your categorization of a one of the most technologically advanced societies in the world really disheartening and insulting to the fundamentals' that America was based on. 

So you are trying to boost hits with your links.  It's a money scam.
Now I get it.

But guess what, I'm done preaching WBers,
ran out of things to say...  and yet you keep going

So what you're saying is:
can if you wish. just add any of your fav tweets, + with a simple 2.2 or 3.3 cap.
Adding the 4 inch has really exapnded the soundstage/presence.

That wide band single driver speakers work much better as a three way?

Here are some tidbits of the article linked below:

Full-Range Drivers are ubiquitous We all listen to full-range drivers everyday.  The smallest are in earphones, cellphones and other devices.

Their "one-driver is best" mantra can actually be agreed to even by those non-aligned. Who would not want a crossover-less driver that can do everything? But real conditions are not so simple.

Most DIY full-range setups are in some ways, if not woefully, inadequate, not to mention not at all full-range

Full range crossover speakers as a concept are very desirable and properly implemented quite good. The key is properly implemented.
