I have a line array per side of 17 3 inch wide ranges, and 32 Dayton Neo tweeters. it goes great down to about 100hz but not much below that even with all those little mids.I use two 12 inch Goldsound(not Goldwood) 12 inch xmax woofers. They are in a vented 12 inch x 7 feet 6 inch sonotube woofer. The foot print is small, and the difference between a vented design and a sealed design at those low levels is negligible in sound, but much deeper in the bass. They kick! The volume size of each woofer is over 9 cu feet. There is no substitute for volume in the box......NONE!
