    I built a sub around a shiva driver. its 100l and tuned to 21hz with a 4inch vent. I notice that when my friend plays his sub (energy 12" ported) it plays a lot louder. There seems to be alot more midbass and kick. I was just wondering if there is anyway to make my sub sound like that?

    His probably has a higher tuning frequency.

    Have you run test tones and compared measurements of the output? If not you should.

    Also are you comparing them located in the same place, in the same room, driven by the same amp? If not then you should

    I think what your friend has is a "boom box". If you can EQ yours, give it a big boost around 40-50Hz and you'll probably get the same result.

    The guys above are right on the money...for kicks though try plugging your port and see if that makes any difference...you can also try moving the sub around the room...chances are there is a spot that will produce the boom you're looking for...or just buy a BFD (there was one in the for sale area) and dial in some boost between 30 and 50hz)
