Hi,
I have been thinking of building a cardioid using a fullrange driver about 6" or 6.5". The goal is to have a constant directivity from high treble 13KHz to about 125 Hz. The lower side could be crossed using a steep crossover to save the fullrange from high excursion and power.
Can you please suggest FRs that have been known to have good polar response above 2KHz and atleast 4mm excursion.
Thanks and Regards,
WA

Good suggestion Stahl… do note that this is a 5.25” driver, but due to large excursion does not suffer in the bottom and has a nice smooth, what i call vintage top-end. The A10.3 provides similar bottom with a flatter more extended top. Sme find that it needs a bit of taming, it does require a lot of break in.
WA do you have an approximate size or cash budget for the project? What kind of amp will you drive it with.

You're going to need a really big horn to manage that. A full-range driver tends to have narrowing directivity (ie, not constant) as frequency rises.

well, mark audio drivers tend to have this less, they mostly have a good dispertion, and the 11MS would have the best one i hear (not first hand info).
BUt i know the 10.3 and the CHN 110 that i have, have very little losses off axis, much less than some of the multiway speakers i have and had in the past in my house. But it's true that most have a very narrow dispertion, especially bigger ones.
