For about a year now I've had my shiva in a rather small 1.5cuft box due to space limitations. The sound is very tight, but does not go quite deep enough.
I've been thinking of seling this sub to a friend and building a new box utilizing the tempest.
I listen to mostly rock, so the sound has to be tight... but I really would like some deep extention.
I was thining of making a 155L box and slot porting it to 20-25Hz, and hope the tempest still provides enough punch when I need it.
The problem I ran into is with the slot ports. According to a few calculations, I would need a cross sectional area of 90sqin to avoid port noise; this would yield a port lengh of over 60inches. :frowning:
Would it be possible to cut down on the cross sectional area and avoid port noise?
BTW: Ive made a small excel spreadshee to help me out with the values, check it out if you wish.
