I am experimenting with an extended bass shelf speaker idea. it will be a wide face and shallow depth box flat againts the wall (and surely i can fill it up with stuff to make it smaller). im going with a 12L box because some other drivers i am playing will fit this box well and i have some spare wood.
is 12L tuned to 45Hz to big and low? i am trying to exploit room gain and a large baffle and positioned near the wall to bring the shelf up 2dB.
i know this is not ideal, looking to build a fun not accurate speaker. or will going this far make the lower end less pronounced?
Green line Vb=12L Fb=45Hz F6=38hz
Pink line Vb=10L Fb=55hz F6=46Hz
normally i saw this driver in 7L boxes.
10L and 7L with Fb55hz have basically the same F6. so might aswell save on wood and use a 7L, but the 12L is still interesting with a flat bass shelf that plays -2dB less but almost 10Hz lower.
anyways, it is a wacky idea with cheap drivers. what are your predictions?
