I am rebuilding a 110 cab, and need an inexpensive tweeter option. Anyone have a guess as to the specs on a tweeter and crossover from a MarkBass CMD121p?? Found the parts available, and may want to use them. The speaker will likely be an Eminence BP102. It's a Workingman's 10 cab, so I could also use a stock SWR (LeSon?) peizo, but may want a high pass to go with that. Ideas?
