RE: Adding a tweeter to MMG

Yes, the 12khz cavity resonance is present in the clones, appears to be worse than in the original, at least initially, later measurements posted at madisound did not appear as bad as the earlier clones.

You can fit a notch filter just as you would for a single Neo8. Personally, I quickly moved to a line array once I heard the individual drivers since I did not want the phase shift from the filter and was aiming for a line array and for a crossover below the midrange, which I knew cancels the resonance at the far field. I did not want to lose the imaging in the vertical dimension that the line source provides.
I ran them to 300hz initially, and used them up to where their dispersion falls off at 5khz. Then I started running them further up and finally stopped low passing them in favor of letting them run and adding in the ribbon as a supertweeter as Apogee and Eminent Tech did.
