I'm getting ready to try building my first pair of wooden horns to use with my Theater 4's replacing the Eminence H290. I'm probably going to use one of Yuichi's designs but I was wondering what the best size would be with the Eminence PSD 2002? I assume the H290 has a fc of 290hz. Is this optimal for the Theater 4's. Yuichi has a 290hz, 300hz and 480hz designs. I assume I could probably also modify these to come up with still more responses. So, what should I build? and don't say a salad bowl, 'cause I can't turn for beans!

Thanks!
