Can you get to 1200 Hz with a "budget" dome tweeter?Why bother with the membrane breakup of a compression driver then? Pretty much the only advantage those have over a dome tweeter in a waveguide is sensitivity and lower frequency extension.
Can you get to 1200 Hz with a "budget" dome tweeter?
SB Acoustics SB26ADC-C000-4 (~50€) in Somasonus (open source) 8" waveguide, frequency response / sensitivity @ 1 watt (2Vrms) on axis, and horizontal directivity:
I'd say that's a YES.
