Thanks so much fore the link! and the more common name of round under bit.
I may have to get a bigger collar for my router if I can't find a 1/4" one when I pull these apart again for the new bases.
Danny, 2 questions.
I just noticed that the woofers are marked M14 & M13. Does it matter which goes where?
Now that the Voce is all gone, is there a OB center you recommend to go with these for HT? Could I build a voce or something similar?
Thanks, Mike
