Hi,

I doubt it has much functionality in that particular application, it may slightly broaden the very high frequency dispersion (just look at the dimensions and the wavelength involved). Also, the low crossover point in the AML1 keeps the dispersion pretty even, if too wide IMHO for far field use.

The AML1 is really a nearfield monitor (and Simon uses it as one IIRC) and in the region of the crossover frequency has a pretty even (wide) directivity. I suspect the narrowing dispersion pattern higher up is not as much of an issue in nearfield applications anyway.

Ciao T
