New two-way ALtec horn design, questions

[atilsley]

I thought GM was saying you could still use the 1200 xover with the 511 , but you might need to physically move the 511 a few inches forward into the listening room so to more align the voice coils of the woofer and HF driver again to maintain a closer phase alignment...?

Thanks...yes, I understood the point about moving the horn to get the optimum alignment. My q was more around the bass driver running up to 1200Hz...as GM had made a comment earlier that he wouldn't like that....hence my q to him about the Model 19, with the 1200Hz xover point.

Kind regards.
