no i just bought the E's their en route and i had this box awhile, i DO NOT wanna damage them, i take advice wisely. so playing high 20's and 30's in this crappy box should be avoided correct? i figure another week or so ill have about enough to get a design by ram and buy the supplies. $175 is enough to fab something to this extent right? I figure 5 cubes ish and about 29hz tuning although sundown reccomends 35hz probably cuz ths Fs of the woofer is 35.8. Can anyone shed light on Fs of woofer and box tuning. not breaking balls here just simple conversation ;-)
