Altec Best, Zilch,

Yes, I am using this with a so and so Altec 19 clone. System is 416-8B, 802D, 612C cabs, and switchable 811/511 horns using tip of the horn/baffle mount of the LF driver acoustical alignment( about 2 1/2 " from edge of the top of the cabinet) from Altec Lansing Application Notes AN-9.

Thanks again.

Abe
