7. Bandpass 6th-Order Series
The .png file in post #11 was incorrect

Pretty interesting result. A single vent delivers about three octaves of deep bass. Less complicated than the 3-chamber 8th-Order Bandpass.

Let's see what's happening with bandpass designs, when optimizing the group delay.

Such group delay optimization will enable delay compensated subtractive crossovers.

Let's compare the four bandpass designs :
- 4th-Order
- 6th-Order Parallel
- 6th-Order Series
- 8th-Order.
