when the frequency is ~1kHz. i.e. the crossover frequency.With AlNiCo Tannoys (up to HPD) the tweeter coil is 1/4 wavelength behind the woofer coil.
Well. Coaxial driver it's the right choice for this moment. I have a tight budget....And very little time available. So any corners that i cut are welcomed.
I don't want to make another thread so...let's focus on the available coaxial drivers.
I have seen this for o long time ago. I like the fact that the HF horn is large!(comparing it with other coaxial drivers)

Eminence is the first on the list...it's cheap and i can get it right away.

And that is where it matters most. But then why might it be different at say 500Hz or 3k?

several other brands now have those smaller PA coaxials
you have to face the fact that fore the midrange driver, when playing any kind of bass/lows the sensitivity goes down a lot
and if it really does have high sensitivity, its only capeable of midrange duty
these limitattions are 'generally speaking' more or less valid fore almost any kind of driver, to some extent
and maybe worth to remind that when you approach the limits of your drivers, everything gets more tricky, and difficult
used on geddes loudspeakers , should be around 60 Euros , 106db

I dont know what we are having this discussion at all , if Geddes says his speakers are the best just use the tweeter with the waveguide
The eminence is as shown in the spec a perfect performing driver very nice flat response, and what is remarkable good is the LF extension. I would not know a better one, despite it is very cheep.Well. Coaxial driver it's the right choice for this moment. I have a tight budget....And very little time available.

The eminence beta12cx would do nice with the bms4550 1" horn driver, bms specs 800Hz XO for that one. And is still affordable.
Curves
I think it is better to have 96 dB and bass extension down to 30-35hz with the beta. Then have a 98-99dB one that only does 50-60Hz.

I've used the DE250 down to 600Hz with a first order crossover. Goes loud, no distortion issues. The only issue I've noticed was horn colouration at the lower cutoff, but that's not the fault of the tweeter.
That's pushing the envelope
What horn type / size were you using?
