How would this design work with the Eminence Sigma Pro 18-A2 8ohm driver. Its also hard to tell from the drawing exactly how the driver opening is put together. Is it completely open and the 2 small braces go across the opening, or is the opening only between the braces??

From the designer:

"The Sigma appears a bit limited to me: Its specs while not too bad are not optimal, its Xmax of 6.1mm is not enough and is going to limit output.
Therefore I do not recommend this driver for the MN-246."

Ok.. Would the Eminence Kilomax be a better choice? *Power handling: 1,250 watts RMS/2,500 watts max *VCdia: 4" *Le: 2.38 mH *Impedance: 8 ohms *Re: 5.84 ohms *Frequency range: 33-600 Hz *Magnet weight: 109 oz. *Fs: 33 Hz *SPL: 95.5 dB 1W/1m *Vas: 8.5 cu. ft. *Qms: 14.24 *Qes: 0.58 *Qts: 0.56 *Xmax: 9.8 mm *Dimensions: Overall Diameter: 18", Cutout Diameter: 16.56", Mounting Depth: 8.15".The XMAX spec seems to be more like the RCF driver.

In the couple years i have been putting cabs together and experimenting i have found that you cannot stray from the driver that a bandpass or bandpass horn box is designed for.
