ok, ive tested 40, 43, 45 and 50hz. 11.7 was the lowest impedence i got. 50hz was the highest, i think it was 15. could a box leak cause higher imp? or if the aero port's connectors arent sealed up well enough? other than that, the best thing i can think of is to put a bunch of 2x4's in the box to make it 4cuft instead of 5cuft. itll change my tuning to 43hz and will give me more port area per cuft. ive also considered plugging the second port for daily. itll bring my tuning down to 30.5hz. might sound a little better, give me my lows back. as long as it doesnt give me port noise. what do you guys think?
but hey, im doing 145db and my subs are only seeing 500w each. so i guess thats some good news.
