That's why a WO for 18's won't work right. A WO for 15's is pushing it a little too far, but can be done. With the 19.O's the horn will get too long and lower the tuning to the point where you will lose output. IMHO, the best bang for your buck with a WO is to build it with 10's. 12's will work good too, but from what I've done and seen not 50% better than 10's like the cone area would seem to dictate. If you want something radical that will probably work, try building a Imperial with the 18's. Otherwise and simple ported box will get crazy.
