Hello all, I am hoping for some knowledge on the subject of infinite baffle subs as I am considering trying IB for the first time when I rebuild my cars system next year.
it is my understanding that IB is more efficient in the sense that it takes way less power to reach a given amount of excursion compared to a sealed box setup. It is my understanding that SPL is largely a matter of cone area x stroke. am I correct so far?
what are the qualities that make a particular sub suited for IB use? I have been searching on google and I am struggling trying to sort the truth from myth.
Also i would like to point out that although I referenced SPL earlier in the post I am not looking for something that is simply loud. I am trying to figure out how to get the clearest deepest bass i can in my car.
for an idea of what kind of volume i normally listen at I am currently running a single 12 sealed on 300 watts and it is almost enough in the 40hz and up range but nowhere near what I would like in the bottom octave.
In theory I could buy a bigger amp and put more power on the sub I have now and than try and EQ out the upper end to even out the sound but 1. I would rather not buy a bigger amp unless I have no other choice and 2 I would like to get some usable trunk space back again by getting the monster box out of my trunk.
Another question, is there anything fundamentally bad about using shallow subs for IB? I understand that shallow subs tend to have way less stroke than standard type subs limiting how loud and low they can go but assuming one had enough cone area to achieve enough displacement within the limited available stroke would it work out?
Sorry for the long ramble, I am dog tired today.
