last night i spent few hours trying to tune the sub.
i notice 4 screws holding sub in so figure just taje those 4 hours and try putting polyfill in..
but i took out 1st screw theb notice 2nd screw was
not tighten all the way so tighten all 4 screws and tried that... i actually did not like it and loosened the screws hopefully close to how it was.
my thinking was on my old box w kicker sub i notice that my bass got loose and less and notice my screws were loose, so tightening them restores my bass in my older situation. but that did not help this case, i fact i kinda think too tight was not good..
ok so that i grabbed 2-3 towels and padded the outer showing edge of pladtic box w the towels. under it and partially covering the sub.
i felt like i heard i drastic improvement with my 1st towel. i added a 2nd, felt like it improved. and added a 3rd towel and felt like it maybe got a little too muffled. so i am using 2 1/2 towels in front of the sub.
ill know more later today when i drive it to hopefully see if it still sounds good to me. i know i was getting happy w it last night.
but i think the sound if i had to describe it, and btw havent put polyfill in it yet.. it sounds more like a ported box bass . where i rather have non-ported box bass, but i at least felt i got a better bass response out of it.
im thinking maybe adding polyfill will make it sound more like a non-ported
bass, so who knows may venture into trying combinations of both.
i think the 1st towel helps alot as that plastic box vibrated alot, so it kinda insulates it.
i just thought id share. who knows i my drive it this afternoon and find what i did did not improve it at all.
