6 Pi Crossover Questions [message #70762]

The 6 Pi crossover specifies L2 with the Eminence Delta 10A and states in a footnote that the tweeter polarity should then be reversed. Is it correct that the B&C DE250 would then be wired in normal polarity (positive to red and negative to black)? Also, is there a way to calculate an additional 2 or 3 db of attenuation to the midrange and tweeter circuits? Because the crossover will be mounted in a separate enclosure it would be easy to add DPDT switches for flat and attenuated tweeter and midrange networks. Thanks for any assistance that you may be able to provide.

Reversing tweeter polarity will "double swap" if using a DE250, so yes, red to positive in that case.

You can increase the midhorn attenuation by ~2.5dB by changing the values of R4 and R5 to 5Ω each. The specified values of R4/R5 (4/8) are set to attenuate 6dB. By shifting values to (5/5), you'll increase attenuation to 8.5dB.

For tweeter values, see the following chart:
