John from AE was very helpful in modeling the cab and slot port earlier in the thread. We slightly modified the original dimension numbers to use with 13" ply to make it easier to build. The idea was to use the size of the tower cab to the driver's advantage, and use it to create a highly capable full range tower. There are very few tower SEOS designs compared to the smaller kits, and I hope these become a template to build off of for anyone interested.
These should be able to take 750w if desired, and keep vent velocity at bay. The port being away from the driver shouldn't affect it as far as I know. If anything, its desired. It will be one of the first builds showing off those new sexy anodized aluminum phase plugs too. Once I gloss this cab up, the whole thing should look and sound extremely sexy. It will complement my SI 18's quite well.
I'm very interested in seeing in room response and excursion with the 32hz tune. I'm guessing I can hit somewhat similar output compared to my BIC F12 in my upstairs family room
