My mid woofs cross at 165 and 2600. They are in a room that is 7.5 ft high and 12 x about 18. They cross to just one 12 inch high xmax woofer per side. Currently they are in very small 3 inch boxes but i plan to double that over the next year.

Even playing such things as Vic Wooten and Bach organ I really don't have the need for more woofers. If I need more woof, I turn the woofer power amp: UP!
