ok, i have an L7 in a 2.5 cubic foot box tuned at 35Hz. it really gets the lows really good. the highs are really really lacking. what would tuning to 38-40Hz do for the highs?

check your low pass filter maybe its down too low.

my question was vague. i meant higher notes in the bass line. i barely heard them. my filters are all set properly.

he is saying turn up the low pass filter to like 120Hz or something.

In terms of boxes, putting it in a smaller, sealed box will get you better response in the high notes.

i already tried that. nothing helps. how about my sub sonic filter? its only on/off. could that be a problem? what would i get if i threw it in the same sized box tuned higher?

about 2.75 at 39hz to keep it flat from 30 up. 44 in port area.

Without some eq'ing it's very hard to get the best of both worlds. I don't know a single sub that manages to cover the normal subwoofer spectrum with the same efficiency. Some do better on the low end, some do better up top. It's just a trade off thing. You have to find what works best for you and go with it. Until you get an EQ on that subwoofer at least.

well, i have a single cab truck. so what a huge truck box? 2.55 cubes @ 39Hz. but, the total port length is only 22.875. how will that effect me?would a long style truck box be ok?it would be really cool looking.

My IDQ is flat in room from 30 to 100hz. It's perfect for most music.


Your problem could be with your vehicle. my old 240sx just didn't allow any decent output from 60hz and up. No matter what sub or placement, it always lacked.
