Well one does need to know more. First off the Theta does not come in the values needed for many locations in this speaker. One would be forced to buy many and begin paralleling to the point that the board would not fit. For example you would need 5 Theta caps in parallel just to hit the value needed for one cap! Cost would also become very high. Also as good as the Theta caps are, I use them in electronics, in crossovers the CSAs are better overall.
