This is interesting about the 2nd harmonic cancellations. Is the equal and oposite reaction limited to 2nd harmonics, and does it make the system less efficient.
With the drivers close together like this. Just how high can this system be used.
What kind of parameters do you use when calculating the rear chamber, and can you actually build the box so it would act like a low pass filter down to 80hz if needed.
thanks,
Bill
