I'm having problems deciding on a design on the Exodus Shiva-x with the Oaudio 500w amp.I want the woofer to go down to about 20hz without much loss of sound pressure and i want to be able to use it's potential but i am restricted with size because i want the subwoofer to be movable(not too heavy) so i think about 120l would be the maximum i can construct
the other problem is that the 4" port is not enough and gives out at about 300w in the 120l box plus i can't spend more on a PR.I tried two 4" ports but the simulations displayed a bump in the 30-40hz region plus a very narrow fall after about 35hz.basically what i want is a woofer that can withstand 500w without chuffing from the port in a box no bigger than 120l
