Hello, I am new to DIY - recently got my feet wet with a Subwoofer build for my HT... This worked out well, and "I would like to take on the challenge of designing a speaker...
This idea is inspired by a 2 way build with the Beyma TPL-150h and Acoustic Elegance TD12m that I fell in love with, but sadly those drivers are a little too costly for me... Looking into lower cost alternatives led me to the AST30130 and Deltalite 2512.
I considered using the smaller 10" version for a better directivity match, but with drivers this large, I'm not sure it would make much of a difference.
My goal is to come up with a fairly efficient speaker that can handle HT abuse while having the unique sound of an AST Tweeter - in a budget friendly way as I plan on building 5 identical speakers!
I am open to any and all suggestions, including different driver pairings...
Like I said, I am new to this and may be way off base with the driver selection...
Thank you in advance for any assistance you may provide!

I use the Deltalite 2512 in a two way with a CD horn above 700 hz. If the AST (Heil AMT clone) can genuinely play that low, you have a good match.
I would recommend including a single capacitor in series with the AST, just as a precaution against DC on the HF driver.
I do not recommend crossing the 2512 much higher, as it starts to SHOUT when the beaming effect begins.
You'll need a BIG box to get the most from the 2512.
3.65 cubic feet, if vented.

FYI - I'm little more than a novice. I was recommended to carefully choose drivers that have smooth response and phase angles for better results with the simple crossover i can build.
I use active crossovers for subwoofers because the necessary parts are large and expensive.

It was chosen as I didn't know any better.... this is my first attempt at a speaker design...
I didn't think the low impedance would be a problem for me though, my amps are stable down through 2ohm...
Sadly, this has been scrapped - I cant get the directivity to work out without dropping in a smaller driver for a mid and that's not quite what I was hoping for...
Im working on a redesign...
Thanks for your input!
