Crazy MTM ?
You think the FR’s would reach?

I havent done too much with horns. If they don’t seem to want to play nice then maybe the boring 2.5way.

Another bent frame. It will straighten
How far away do you sit? I'd personally go for the "boring" 2.5way.
Not really sitting. 20-80ft listening distance indoors.
If the spec sheet on the 15" is accurate, it's better off-axis than I would have guessed. Where are you planning on crossing these?
If anyone can do it, you're the guy. Punch conventional wisdom right in the face!!
At that distance, the narrow polar lobe from the large C-C distance of 15" woofers will be much less of an issue. Go for the MTM if that's what you want to do!
If my assumption about intended typical install location is correct, the MTM should work really well at helping minimize reflections from the ceilings. That is actually a benefit of the narrow vertical listening axis. I believe that is exactly what D'Apolito stated was a design goal of the MTM alignment. Go for it. Maybe I'll stop by and give it a listen when you get the prototype finished.
After some very quick measurements this morning I’m gonna try it. Distortion low in the tweeter and high in the 15 is going to be close to a no no tho, like every other design I’ve done in the last few years.
Pretty cool, looks like the tweeter will just have enough efficiency once the response is smoothed out.
Wish it didn’t die after 10k. But it is what it is. I aint
buying a different one.
No, turning back now.!
What diameter bit is typically used in a CNC router? Looks nice and small.
A CNC router is just a router after all, so you can load it up with whatever bit you want really, but people usually use 1/4" because the math is easy and it makes for not a huge amount of waste material.
Yes. 1/4” Up spiral
That is sweet. Wish I had one and knew how to make it go.
Lol. Me not too smart and fingered it out.
Progress!!
ok, I'm sold on your CNC build
can you provide a link to your machine- thx

IS this renamed "CNC Router Parts"? Website and CNC models looks very similar
I believe it’s the same company one just bought out the other
Brad, the specs show this cnc weighing in at 420lbs!! (484lbs with optional leg kit). That is one mean machine!!
It’s built well.
Should be taking measurements tomorrow sometime.
Getting there! I’ve done no off axis measurements yet, this might be a little time consuming.
Those should ROCK!
Hell yeah!
I've seen bar bands with smaller PA mains than that.
