I saw some older posts regarding the Stage Four Pi 18. Seems like a 4 PI 18 could work with the Emminence Magnum, Omega or Sigma 18" drivers? I saw a reference to the Omega used in the Stage 4 Pi 18"; similar volume to the Theater 4's. I did not see in the forums where it was either sold or discontinued. Did you sell it at one time? Are there any problems with it? Do you still have the plans for it? I would like to get SET style efficient bass slam in an under 10 ft3 two-way speaker without corner loading, horns, bi-amping, active crossovers, or powered subs. I am willing to go to 500hz crossover to get there. I have not figured out the Pi align software yet, but some of the other box calculators I tried showed some reasonable sizes with the Emminence 18" drivers. Possible, good idea, bad idea? I am assuming a Stage four Pi 18 would have considerable bass slam?
Thanks
