The BMS 4590 is a co-axial compression driver with two annular diaphragms.

On a non-beaming horn, it could have much wider HF dispersion.

If you consider that good dispersion, what does a bad dispersion look like ?
Hi Art, how are you doing?

OTOH, this horn has almost 90 degree dispersion at 15K. That is pretty good. To me its more that it loses its pattern control, not that it doesn't have enough HF dispersion.

Based on discussion here, I conclude that combing filtering won't be important for highs, so a Tweeter could be added later, if there is not easy solution with the horn implementation.

What I really dislike about designing this Horn, is that all the Mids (<1khz) are performed by the Woofer.
Wondering how big the horn has to be to cut lower.
I also have seen implementations with a Bruce Edgar Mid horn.

Do you think this affects mid (vocal) quality?
What are your thoughts?

Cheers!
Carlos

small tweeters does not match well with bigger mid horns

depends on the woofer type, and size ofcourse

you need a relatively big midhorn/waveguide with a cone driver
and a realtively big waveguide on top, with 1" driver

midhorn is best lifted off the floor (unless its very big and able to stand on its own)
a sub of whatever design could be convenient for that, but doesnt have to be

its really not be a matter of what might be the best
but much more about what you will be able to make work

its really pointless to suggest a design if you dont understand what it takes to make it work

someone is selling 4 beymas 12ml100 in chile, at USA prices.
This seems to be a 12 inch driver that can reach 40hz in bass reflex enclosure !!??

Should I replace my pair of Eminence Omega Pro 18 for a pair of Beymas 12ml100?
I would like to doit if I am getting more Finesse and subtleness in the midrange.
And of course, thinking in adding a Horn on top.

If it reaches 40hz solid, sounds a good deal to me...

subs are secondary add ons

you mean 12MI100 ?
no, its a big midrange only
not enough Xmax to play much bass, high Fs, very low Qts
a genuine midhorn driver

might work well in a big midhorn rolling off 100-150hz

Thanks. Data sheet said up to 40hz in bass reflex enclosure, then I thought it could be good to blend with a horn.
