I am going to make a pair of 2Pi's for my tube amps to go in a different room. If you could please send box dimensions and port dimension that would be great.

would a Beta, or any other driver for that matter, be a better choice than the Alpha?

I have some Motorola KSN 1016. the specs look similar to KSN 1038.
1038 is the one, or no difference?

is the spl of 97 for this speaker, a plus 3db of the two 94 driver?
+3 for two of the same?

Thanks!

Bill
