hi all,

hi gm, hi earl:

think 411's - still new to altec
- didn't eyeball them - should
be at least 4 of them.

fellow may have other woofers - has
a big library of drivers from the last
50 years or so...

will still pursue 909/515 for now but
good to know other drivers 'to hand'
for further experiment.

thanks for following,

a

ps - gm - thanks for help with little
coral driver calc at diyaudio the other
year - had to pass on the drivers to
another enthusiast though....
