    Actually, many consider that Emilar "Bowtie" horn superior to the Altec sectorals ( due to the Emilars heavier casting > making it less prone to ringing artifacts, etc ) .

    It's the same driver as the model 2203A.

    The 4315 ( 4-way ) used one or the other model.

    Recone parts are ( apparently ) no longer available ( so its very much an obsolete driver ).

    It's cool that you are finally enjoying these ( since you started this journey back in early 2918 ).

    You got that right!

    Those wanting a 12" version of 2216nd have only to modify the 2262H ( in the same way the 2265H was modified into a 2216nd ) .

    Do you have private intel that the 2216nd-1 has around 15-30 grams more MMS than the 2216nd ?

    If so, please share.
