ALTEC HORN + JBL + LOWTHER>

IM also lover of this kind of speaker...really great.
but  u should know before playing it.
1) Size,  all those old speaker...need a lot of space ...at least 12" woofer or better 15" woofer. except lowther.

2) Ohm - those speaker ,,always in 16ohms,,,thise need ur amp to match
with it.   (this why also using tube amp is better. due to  matching transformer )

first solve this two problem,,, then enter the gate having fun.
