No, it's a crossover effect of two-way speakers with wavguide/horn, where woofer and waveguide pattern sum. This will leave a small dent in DI and PR, but you cannot hear it, it is a problem on graphs.As it's been measured by Harman this speaker seems to have some BBC dip, expect that it's at a perceptually wrong range.
Maybe it should have been designed a 3-way.
a phenomenon of the LR4 XO - the crossover has a 3db dip in sound power at the XO frequency resulting in the rise/wiggle in the DI jsut after the XO frequencyThe crossover is at 700Hz, so what is going on at 1000Hz? Why does the directivity index dip like that? Baffle diffraction?
Yes, its the passive sibling of the M2.Oh wow, this is the big one with the 15" woofer.
The M2 has more cancelations and dips While the 4367 has a high frequency boost that is offset by the listening window. I would Hardly say the M2 has better measurements all around. SPECIALLY for an active design.The M2 has better measurements all around IMO
I'm talking about off-axis measurements. It goes without saying that if you are using an active crossover you will be using EQ to fix any frequency response anomalies. The M2 has constant directivity from 700Hz on up while the 4367 has wonky directivity up to like 1800Hz apparently because of the passive crossover.The M2 has more cancelations and dips While the 4367 has a high frequency boost that is offset by the listening window.
