I priced the parts needed to upgrade the tweeter crossover in the 3 Pi Theater using Northcreek parts. They don't have the exact cap values needed, so it will be necessary to "cascade" values (e.g. use a 6.0uF and a 2.0uF to get 8uF), but that's what they recommend anyway. Total cost to upgrade all the caps, including pricey $14.70 Crescendo caps for the .47uF L-pad bypass, upgrading the 25 ohm L Pad series resistor to two parallel 50 ohm Northcreeks, and rewiring everything with their TefFlex teflon insulated wire, will be $124.90 for both speakers. That may seem like a lot of money for a tweeter crossove upgrade, but the 3 Pi sound quality is up there with my Eros MKII's and Selah Audio line arrays, so I belive it's justified. I'll report on the results when the changes have been made and given time to settle in.
