WHAT DO YOU GUYS MEAN WHEN SAYING, "TUNING AN ENCLOSURE TO SAY 30HZ?" HOW DO YOU EXACTLY DO IT? BY JUST DETERMINING BOX SIZE? OR I STILL HAVE TO COMPUTE FOR A LOT MORE STUFF?

WHAT MID&HI DRIVERS ARE YOU PLANNING TO USE? AND SORRY BUT HOW DO WE CONVERT A CU. FT TO LITERS?

ARE PRO HORN DRIVERS ROLLED OFF AT THE VERY TOP END AT AROUND 12KHZ? WILL I LOSE SOME SPARKLE AND CLARITY IN MY MUSIC? MANY PRO SET UP USE EQ TO COMPENSATE, WILL I STILL HAVE TO USE EQ? DO I ABSOLUTLEY NEED TWEETERS OF ULTRA-HIGH FREQ. SUCH AS THE 2404H TO HAVE SOME SPARK IN MY MUSIC?

HERE NOW IS MY REVISED PLAN FOR DRIVER SET-UP FROM JBL, CAN YOU COMMENT IF THIS IS ALREADY A RIGHT SET-UP?
18" 2242H FROM 25HZ-100HZ VIA SOLIDSTATE AMP

2" 2246H FROM 1.2KHZ-12KHZ VIA 22-WATT SET AMP
